Hello everyone,
So I just picked up a 2001 Yup 50 for $100...... Starts right up every time and runs great. The only thing is missing a few body parts (bottom skirts on both sides and under seat cover). So I figured being 49cc and me @ 220lbs that I would be lucky to break 40mph....... To my suprise though I can hit 47/48mph with no problem. So is this little 2 stroke this fast or has someone tuned/de-restricted it? How to tell without tearing apart?
Thanks and happy to find this forum (Although there's no "YUP" section.... What's up with that?)
-
BTW: Speedo is correct as I used my GPS to confirm speed. Also, It isn't over powerful taking off, But as stated I can hit right near 50mph after a few blocks.
Any knowledge here would be appreciated ;)
-
Most air cooler 50cc scooters will do at least 40mph, even the 4 stroke scoots with
just 2-3hp so it's not surprise yours will do more. 2 stroke air cooled 50cc scoots
are usually in the 3,x to 4hp category.
Water cooled 50cc 2 stroke scoots are in the 4-6hp bracket and do anywhere from
45 to 55mph indicated.
Some have less accurate speedos then others, though.
And your weight won't do much for the top speed, however it will do a lot with
your acceleration.

Okay, Thanks for the info Cortez. Now to find these missing body parts..... I don't think will be easy though!

Hello sir,
Where did you find your horsepower figures? I recently got a dyno, and those numbers are pretty much what I'm seeing. Many 50cc 4T scooters in the 2ish HP range, and my People 50 comes in at about 4.5 HP. A buddies SYM Jet Euro with a Malossi sport shows 6.45...
-
Um, yeah, it's from my head, sorry. ;D
I've been working with scoots since 2004, few different brands since then
(peugeot, kymco, sym, some chinese crap etc), then worked at a newspaper
where I wrote for the car/bike section, and from last December I'm again in
the bike industry so.. these figures tend to remain in my head.
No dyno stuff, just manufacturer rated power.
Some of the most powerful 2 stroke 50cc STOCK bikes were based on the piaggio engine
used in Gilera Runner, Piaggio NRG and Aprilia SR50. Yamaha Aerox was up there too, and
later on, the Peugeot Jetforce C-TECH.
All of these could hit almost 55mph stock and had suspension and brakes to match.
But I digress..
-
Digress away...
-
So....... Everyone agrees!!??
-
With what? That your scoot is Too good? Ok!
I think it is a given your scoot is de restricted.
-
LOL.... Yeah, I must have a better revision or a "Limited Edition" model ;)
-
Zombie.... I'll post some after pics as soon as I'm finished painting this weekend
Attached a Before..
-
Speedo...
-
That is actually a Very cool looking scoot! I would trash the mud flap, and the front fender but with some new color, and maybe some "race" stickers... That would be cool as sh**! Kinda looks like a People/ZX hybrid.
Where is it from? That is the first Yup I've seen besides the Factory picts.
-
TampaBay area.... I see your in FL as well?
-
I thought it looked more like the Sting than a People..... The title just says "Kymco"..... so I actually thought it was a sting when I bought it...... SUPER CHEAP too! Will pay for itself in fuel costs vs the V8 @ 17mpg <-----Ouch
-
I'm up in Carrabelle. I haven't had a car/truck/motorcycle on the road in years. Fl is truly the year round scooter capitol.
-
Agreed.... Perfect year round weather. Well, Barring the short afternoon showers. I have to admit, I'm really lovin riding this around. I have some turn signal mirrors on the way and I want to buy one of those little MP3 amp/speaker/alarm kits. Anyways, Almost finished with my $18.74 back yard paint job..... and I removed the rear tire guard as you suggested. I also think it looks better with the front fender off... what do you think? Also, Too blue?
-
Front
-
Rear
-
With fender
-
Completely my opinion but I love the blue. It looks so much more updated. The Airbox is a bit much. Perhaps doing the cover to match the silver/grey would be more "classy". I'd smash that fender into bits too. Just so I wasn't tempted to use it.
IMHO... It looks like a completely modern "cool" scoot. The kind that get girls at the beach to follow you. (in the commercial anyway).
Graet job for 20 bucks.
-
With new turn signal mirrors, painted to match..... And of course the blue intake cover revised....You we're right Zombie ;)
Scoot @ $100
Paint @ $22 (Total for complete scoot @ primer/base/clear)
New Mirrors @ $10
Total invested $132 .... Already damn close to paying for itself in fuel costs ;)
Tires, Trunk and audio coming next week:
2x 130/70/12 Pirelli's
240watt Amp/X-over/Capacitor/Marine speakers @ 2x 2" tweeters - 2x 4" mids - 2x 5.25" 3 way controlled with a mounted 4gb waterproof MP3 player
If anything, I havin a great time doin this!
-
From side

Your scoot looks great!
Where did you get the signal mirrors for $10?
-
Ebay..... They were originally burnt orange and I got em for $10 plus free shipping. The shipping cost the seller $17!!! I thought he would back out of the sale, but here they are. Wish all Ebayer's were as trustworthy
-
In 1,217 ebay buys I've only had 2 poor sellers, and they are no longer selling... Paypal takes GREAT care of buyers. (Just NEVER list/link your bank account) I use ONLY debit cards for ebay. Pay 10 bucks for an item, and add ten bucks to the card.
