Today my husband purchased a Kymko Agility 50 for our son. We got a great deal on a 2009 with 942 miles! It had not had the 300 mile oil change, however, and had been sitting up for two years in a garage and would start but not stay on. We took it a kymko dealer who inspected, did the oil change and service, replaced the carb. and made sure all else was good. They did say that at 900 miles the engine wasn't really broken in yet and it would take until 1,200 - 1,500 to be broken in. We were so elated to have gotten such a great deal and can't wait to take it to our son in college. However, when my husband rode it back he could only reach a top speed of 30 mph. He is 6'8" and weighs 290 so I thought perhaps he was on the high end of the weight limit. However, looking in the manual it says max weight is 500 plus pounds. My question is whether the scooter not reaching 40-45 mph is due to my husband's weight or perhaps the motor isn't fully broken in yet...or other reason???? I am concerned that in traffic our son will need to reach 40-45 to keep from getting run over even in the city. Our son weighs about 190 pounds. Should I be concerned there is another problem? Please share your insights. Thanks.

Hello,
On a standard Kymco Agility 50cc scooter the top speed you will reach is 30mph. This is due to the restrictions that don't allow it too go any faster. However you can take these off so too speak.
There are many tutorials online, however before you do anything make sure you know what you are doing. This involves cutting the CDI, replacing the drive boss to a smooth lip and going up a jet size. I made the mistake of fiddling when I didn't know exactly what too do and damaged the bike. Also take care in knowing that insurance policy can be breached if you de restrict the bike.
Once the restrictions are taken off it will be able too reach 45 - 48mph.
Hope I helped!

This is a thread on this forum that explains exactly what needs to be done. I did mine myself. Really wasn't difficult at all. If your husband has any mechanical knowledge he will be able to do it. My 2009 A50 goes around 45-47. I ride it to work everyday in the summer and have no problem with being run off the road.
If you keep searching this forum you can find more threads on cutting the CDI. Here is the video I used to cut mine. Cutting Kymco Agility 50cc CDI (http://www.youtube.com/watch?v=ZJtxkMgRYbw#)
I could not see the wire when I cut it but I tried to cut it exactly like the video. Once I put it back in I could tell it had worked.
Hope this helps.

^^^ as stated derestrict and should be steadily getting around 40 mph with no other modifications.
If yours is like mine it may indicate approx 45mph on the speedometer, but mine is about 5 mph off as well as others. Just derestricted I average 38-41 when riding. not super fast but enough that I don't get ran over on the street with a 45mph speed limit.
If you upgrade variator and possibly weights then could easily get 45+. most decent variators are less than $100.
-
Hello, I doubt very seriously that the figure of "500 pounds" in the manual represents the rider weight.
I'm pretty certain what you are reading is the total weight of scooter and rider.
Nevertheless, your 290 husband and 190 son are likely within the weigth limits of this scooter.
As stated very well, here - make certain you know how to derestrict this scooter. Your dealer would be a good source for info on safely doing this procedure. (he'll do it, or likely recommend someone who has experience doing it) The idea being to improve this scooter's cruising speed - without making it nearly useless.

he could only reach a top speed of 30 mph
30mph is just about all you can get out of an unrestricted Kymco 4-stroke. Maybe 35mph with a tailwind and a small, light rider! But 45mph on a stock 4-stroke Kymco 50cc? Not in this lifetime!
-
The only mention of 45mph was with derestricted engines. An indicated 45mph would actually be 40mph which is pretty usual for any 50cc machine without restrictions.
-
40mph which is pretty usual for any 50cc machine without restrictions.
A 2-stroke 50cc Kymco might get to 40mph, but a stock Kymco 50cc 4-stroke won't get anything like 40mph. A showroom-stock restricted 50cc 4-stroke can barely make it to 25mph!
-
JJJoseph sorry but you are incorrect. My agility when it is running is only derestricted by changing the boss and cutting the original cdi. and I was hitting 40MPH GPS indicated (Speedo said 45ish). everything stock, variator, roller weight, belt. etc. just normal derestriction.
Many have fitted just a new variator and have gotten 45mph on these scooters. MIne is a 4-stroke and I weigh in at 230lbs.
-

I've never seen speeds like that - I'll give you maybe 40mph downhill in good weather, but 30mph is more like it on a stock Kymco. I'm a little suspicious because the variator has no effect on top speed.
-
Any 50cc unrestricted will hit 40mph, even chinese duds. If they didnt then no-one would buy them world wide. Honda 50's etc were capable of 40mph fifty years ago. If you check out the horse power of the machine you will see that 40 is realistic. My a50 hits a gps checked 41mph on level ground with no wind and I weigh 254 pounds.
The variator has an effect on top speed due to its profile. One variator profile might be such that the belt is carried higher up the pulleys therefore a higher gear effect is produced. Another variator with a profile biased towards acceleration would have a profile that favours the belt into a tighter smaller configuration so lowering the gearing. By the way nearly all so-called peformance variators come supplied with a new variator boss that is reduced in length so allowing the variator faces to be closer together and raising the overall gearing.
In my time I have owned Honda c50,c70,c90,s50,ss50, Suzuki a50, ap50, Yamaha fs1e, townmate, Rd50, Mobylette 50, Raliegh 50, Puchmaxi, Piaggio zip50, Velo Solex. I have spent a lot of time on 50's doing a genuine 40MPH!!
If your unrestricted 50 cannot achieve 40mph then there is something wrong with it.
-
Completely agree with reg. When I derestricted my A50 by changing to a smooth drive boss and unrestricted CDI I was reaching about 39-40mph. Then i went to a performance variator that came with a slightly shorter drive boss and I have been reaching about 43 mph GPS verified. And that is on flat ground without much wind. I'm sorry JJJoseph, you are wrong.
-

LOL! If those 50-year old scoots are your experience, then you're seriously behind the times! A new CARB/EPA certified 50cc "moped" will top out at 25mph. That's all you get. And the variator, usually limited by the size of the case, won't make a bit of difference. But if your 250lb self can get 40mph on one of these, you've experienced a modern miracle! Properly unrestricted, you can maybe get near 40mph, but I don't believe you'll ever get more than 40mph, even down hill with a tailwind because they're still RPM-limited by the CDI. If you're getting more than 40mph, you've done something else that you're not telling us about.
-
Well Joey you have brought something new to this forum after all. Childish arrogance and an obvious insecurity.
I notice you show yourself as having a Kymco Sento, so why all the jealous postings on the Agility forum?
I think your constant whinging about Agility top speed betrays a good degree of self pity and self annoyance cos you wish that you had got an Agility instead of your sento.
What happened ? are you regularly overtaken by a local guy on an Agility? is this the source of your anger and envy?
Chill out, let it go and just enjoy going to the local store to pick up your mommas shopping on your toy town trainer scoot.
I am just looking back through the threads to see if you listed the first day that you rode it without stabiliser wheels on the back.
-
Kudos to reg.
JJ move along since you obviously know nothing about the capabilites of the Agility or pretty much any 50cc.
You continue to deny facts after many have advised otherwise.
The only fact that you seem to have stated is the cdi is RPM limited. However we have all stated our scooters have been derestricted (unrestricted as you say). This includes removing the RPM limiter of the cdi.
But me and my fellow Agility riders will ride our secretly modified modern miracles everyday.
To the original poster. I apologize this thread has been threadjacked by stupidity. Please listen to the people who ride these scooters daily and know their abilities. Your scooter can easily hit 40 MPH on a flat surface when properly derestricted.
-
GET HIM!!!!! Lol!!!! Ive seen some of joeys replies here and there, he seems constipated? Id suggest he ride slower. All those bumps take their toll.
-
The agility 50 is a pretty quick and powerful one if fully derestricted.
With the CDI cut, a malossi multivar (with smooth boss), a malossi x-kevlar belt (2% longer than stock), a free-flow air filter and #84 jet i could hit a stable top speed of 72 km/h (little over 44 mph) @ 9000 rpm, where the limit are after the CDI cut. I will have to mention that i was only 55 kg (120 lb) at the time and i was not using mirrors or having a top-box and that this was with all new parts in the CVT on an engine that had only gone 8000 km (5000 miles). :)
With worn CVT parts, higher weight and more wind resistance i have only been able to hit 65 km/h (40 mph).
All speeds are gps verified.
-
Baddi is your Agility a 4 stroke or 2 stroke? Just curious as I am trying to 40mph on the flat out of my 4 stroke 2015 Super 8 50R
Thanks

All GPS-verified, same straight road, both way average speed measuring technique, same fuel and oil, carb always tuned speeds:
Derestricted: Variator boss, airbox/intake manifold, cdi cut, different roller weights (5,5gr).
A50 derestricted stock: 63 km/h
A50 derestricted Malossi multivar and #80 jet: 67 km/h
A50, Malossi multivar, drilled open airbox, #84 jet: 73 km/h and hit rev limiter (only capable of reaching this speed when tucked in)
A80, 72cc big bore kit, malossi multivar, drilled open airbox, #90 jet, camshaft stock: 73 km/h (need to tuck in slightly to reach top speed)
A80, 72cc big bore kit, malossi multivar, drilled open airbox, #90 jet, camshaft A9: 73 km/h (Basically almost reach this speed unless headwind is strong-ish)
All done on the same 2007 Kymco agility under the same circumstances.

I can see you are having fun !
Excellent !
I did not see where you mentioned your pipe. A tuned pipe can be night and day for a 2 stroke and a small bonus for a 4 stroke.
If your carb is easily accessible, and you are having fun with jetting, Perhaps you could try sloshing so RC nitro fuel at it ?
There's quite a number of factors to consider, so it will be necessary and very precise.
An error can easily bring a burned piston, or worse.
Best to have a second carb to set up for running alcohol/nitro fuel.
Take notes of air temp and humidity each time you run.
Try running a search for an 1/8th mile timing light... an app, or perhaps DIY diagrams ??
Always do your time trial early in the morning... better air !
I suppose next step in the game is to give nitrous a try.
Or you could try this Budd Fabb link for inspiration !

I`m definitely having fun with my scooter indeed! ;D
I`ve ran the stock pipe and a free-flowing Leovince pipe with no difference in the means of performance between them two with the 50cc.
With the 72cc the stock muffler gave slower acceleration (logic, as it`s really blocking the exhaust flow.) but the same top speed.
Indeed, it makes a huge difference on a two stroke. On four strokes it can potentially give some extra performance (5%-ish) but that`s only really happening with bigger engines (We`re talking real motorcycles, 300cc+).
I will perhaps try experimenting with a free-flow open filter. Nitrous is too dangerous for the engine and since this is my main means of transport being a teenager, I`d rather keep her in one piece ;)

My 2015 Super 8 based on the Agility platform (but a few pounds heavier) would do 28mph restricted. I live on very flat land and the highest speed limit in my town in 35 mph. After clipping the CDI red/purple wire I get to 33 mph pretty easily and 35 mph if I wind it out over a longer distance. 35 mph is about the max I want to do. My understanding is a restricted Kymco OEM CDI caps RPMs at 7500 but 'unrestricted' still caps RPMs at 9000. The furtherest 35 mph stretch I have to ride is ~ 2 miles and don't drive it but once or twice a week. Also, I now have Mobil 1 synthetic engine oil and Mobil 1 75W-90 gear oil on board and I know that delivers significantly greater protection then any conventional oil. I'd be more concerned about the unrestricted CDI if I was driving down long steep hills, but on flat land I don't see me burning anything up... and no posts anywhere on the web with a Kymco owner that has had such a failure, yet plenty derestrict their CDIs.
After researching the pros/cons of switching to a smooth variator boss, I'm sticking with the OEM one with the shoulder. Based on all I've learned how things function the only downside of staying OEM is limited top speed (and I'm going as fast as I want to go already)and the motor will work harder with higher RPMs more often... but these engines are bullet proof and I have high confidence in synthetic engine oil.
The downside of switching to a smooth variator boss is that while the top end is increased and the engine does not work as hard, the top end becomes weak and you really need increased jets to maximize impact. Related, I've also read posts that some have degraded the smooth acceleration potential once they put in a smooth boss.. i.e., other issues surfaced for whatever reason. Not to mention in a town with 35 mph max speed limits I create more legal risk potential.
In summary, while I know some are adamant that you MUST put in a smooth variator boss if you derestrict the CDI, I've found no proof anywhere on the web to prove the risk, particularly with a Kymco. I do understand the conceptual risk.

What exactly does it mean open air box ????
-
Take it literally. I drilled my stock airbox open. All the existing holes are now wider and I`ve drilled about 10 5mm diameter holes in the side for better airflow. Removed all rough edges and restrictions in the tube going to the carb. All airflow optimised.
-
Is the following true? "Also take care in knowing that insurance policy can be breached if you de restrict the bike."
-
It`s true.
A modified vehicle doesn`t comply with the factory specs and isn`t technically legal. They won`t care about, for example, different headlights (if they function normally) but if you get involved in a more than stock-speed accident they can choose not to pay.
That`s the case in the Netherlands, I`d guess it would be about the same everywhere else.
For legal advice please look through your countries/states laws and your insurance companies` rules.
-
Sounds reasonable. Thank you.
-
I'll put my Agility on a dyno in a few days. Aiming for 6-ish horsepower ^^
-
4,4hp it is. Bummer. The torque is there though with a whopping 17,9Nm 8). Kind-of doubting about the accuracy, but the HP seems legit (top speed of 73km/h requires about that amount of hp) so the torque must be legit too. (https://ibb.co/fnz5dQ)

I was dealing with my machine these days, I changed 2 sets of rolls after I discovered that the original 6.5 grams were pretty worn in places. I first put 5.5 g but I did not like something, then I put 6.0 g and opened the filter box. There is a better take-off at low revs and a good start but I think too early on top gear and dying on the slopes.In the morning I could not pull it out of the garage, where it had a steep slope of 20 meters, died in the middle. Now I can not decide which rolls to leave, rather tend to 5.5 grams. Separately the variator may be quite worn out and may need a new one. There are a lot of dug in the grooves on the rollers, which is not normal for me.
-
How many grams of rolls is best to drive Malossi Multivar ?? I think I buy one, but I do not know which rolls to mount it, it comes with 6.5g, and I have 6.0 and 5.5g.
-
5,5 grams is definetly the way to go, both in terms of acceleration and in top speed.
-

If you're sure 100% I'll trust you, because I'm tired of taking this variator. Still, I am 110 kg and the bike has 16 inches of wheels. The set comes with a white central spring.
-
Totally frustrated by Malossi Multivar, a complete joke. I installed it yesterday with the white spring, the scooter died totally at the start, barely moved to 10 km / h, then left slightly but was worse than the original variator. Slowly moving to 30 km / h,during that time he moves on pushing as if something stops him and runs afterwards,then things get better. Interestingly, something depends on the temperature of the engine when it is cold is totally dead, in the morning I had to push him down the hill from the garage and the first 2 km. Could not lift more than 10 km / h, I had to pick it up and force it several times to go normally bad. All of this is with 5.5 grams of rolls, today I put the original 6 grams of Malossi, to see what happens. Is not it a problem that I do not know what a jet is installed ??? The original variator is worn out and rolls along the rollers. Before I climbed the hills at 30 km / h, now I'm doing it at 20 km / h. What to do, I'm really disappointed for those 60 euros.
-
Mury, I haven't been on in well over a year but today is your lucky day I guess.
The issue is not likely the Malossi Multivar. I too have that with 6g rollers and the white spring installed. Your issue sounds more like an engine issue. The Malossi is an improvement over the original variator in nearly every way. The 6 g rollers should give better acceleration as well, and the white contra spring will provide an rpm increase as you hit hills/slopes. This should increase your climbing speed.
From the sounds of it, trying to understand what you're saying, the engine seems bogged down. This is not related to the variator. I have had many issues with stale/bad gas where the scooter just does not want to run hard and bogs down continuously. There could also be an issue with your carburetor being clogged up or dirty that would cause this. Another issue could be your valves are out of spec (not likely) or your spark plug is shot.
Your scooter will always lack power when not warmed up. It will be even worse in cold, wet, humid conditions.
You must be sure to let your scooter warm up for 2 minutes or so before you ride it. You should do this every time whether its cold out or warm out. If you start the scooter and ride it hard immediately you can hurt you piston/cylinder and lose engine power over time. On a cold engine the piston is smaller than the cylinder and there is little oil on the cylinder walls. This can cause blow-back which will gunk up the walls or worse you could score the walls due to lack of oil lubrication. This wont happen right away but over a period of time of not letting the engine warm up these issues can occur.
First I'd start by letting the scoot warm up before driving. Next I'd add some fuel stabilizer and carb cleaner to your gas. You can find some products that do both in one bottle. If that doesn't solve it then dig into the other things i discussed.
Hope this help.

The problem was in the air, after the box that had been drilled. Apparently, with the new variator, we did not get the fuel, after we blocked the box, the scooter flipped. Now I fly like a bird, and with my 110 kg. Raises 60 on flat and 75 downhill.I'm very happy

The only way any Agility could ever do 40mph is when tossed off the top of a 10 storey building. Most likely you guys are reading the "Km" on the speedometer! The red mark on the speedo at "45" is tops for a 50cc factory Kymco of any model, and this is in kilometers. A lot of people who just fell off the back of the potato truck think that this is "mph" - but it isn't. In miles-per-hour this is just under 30mph, which is the legal limit in most of Europe and the USA. In Germany, the traffic cops will impound your 50cc scoot if you're going over 45kph, and the same in many states. In other words, it's AGAINST THE LAW to sell a 50cc that will do more than 28mph (45kph). Kymco has to stay within the law and makes it really difficult to modify your 50cc scoot to go over 30mph, and dealers won't even talk about de-restricting. Anybody who says their stock 50cc Kymco will do 40mph out-of-the-box is talking nonsense. Now, on the other hand, you CAN modify a 50cc Kymco to do 50mph, but it's expensive and its life will be much shorter.
-
You really know way less than you think... My agility I put a smooth boss in it and that's it and now it does 38mph on flat... I ordered more parts and should do about 45 on flat. stop trying to be a smartass and pretending that you know everything because you clearly don't. If you think an a50 de-restricted won't do 45 flat then you really must have a sh** agility if you even have one. stop complaining and saying bullsh** and move on.
