Purchased a 2019 UVX 700i LE Hunter model. Not that I hunt! It was used by the Kymco center in South Carolina. It was never sold but had 741 miles on it. The dealer made it worth to me to drive a few hours and purchase it. Has a lot of neat extras, power steering, bed extender, roof, windshield, 14" alloys, 26" tires, Warne winch installed and some funky plates mounted in the bed for gun boots. I took them out, didn't want my German Shephard bumping into them on rides. Put 40 some miles on it in the week I have owned it. Nice ride, pretty good power and my German Shephard loves it! Still have my MXU 450I and have no plans of letting it go anytime soon. Just thought I would share!

Like the title asks. Wondering who has the most miles and hours on a 450 with nothing but normal maintenance? Asking you UTV guys because there seems to be 10 times as many of you as the ATV owners.

Last Friday my clutches came back from AirDam. Had the day off so I pulled the clutches off. I tapped the weights out of the rollers and drilled a 1/8" hole all the way through each weight. Deburred the holes and tapped back into their sleeve. This should raises the engagement of the CVT by a couple of hundred rpm. Raising torque on take off. Plus it's free, lol! My feelings on the AirDam clutch work, well worth the money. I am so sorry my Samsung Galaxy took a crap so I have no test data to losing the phone and app for this last mod, my clutch system. I had already installed my 25" Carlise radials so data would be skewed anyways. My feelings after putting several hard miles on my Kymco this morning, pulling the clutches, and putting several more hard miles on it after lunch!!! It seems ever so slightly lower geared than the 2MM shim mod made it. If I was to guess it is like starting off with 2.25-2.5mm of shims. But, a big but, I gained all my top speed back. With the 2mm of shims my top speed dropped from 56mph to 48mph. It is back, and that is with 1" taller tires so my speedometer is probably reading several mph lower than I am actually going. !

I decided to do a little back to back acceleration testing on my MXU450i against my wife's 450 Grizzly. They are both similar sized and weight machines. Her 2010 isn't too long in the tooth and I just adjusted valves late last summer. Truthfully I already felt the Kymco was faster and a pair of unbiased people stated it was, oldest daughter and her boy friend. I remembered I had down loaded an app to my phone last year to check the accuracy of my Subaru Brat speedometer because I run tires 1.75" taller than were stock. Looking at the app yesterday I noticed it had 0-60 and 0-100 times. Took me a little to figure out but I was able to change it to kilometers per hour and checked it in my truck to see how it worked. Very good!!

On to the test, my wife's Grizzly has a winch, Kymco doesn't. So to balance it out I filled the tank on the Kymco to the top. Her Yamaha had 1/4 tank. I set all air pressures on 5 lbs. even. I started all runs at the road end of my driveway in the gravel, it is fairly hard backed. That allowed me distance into the yard if I needed it for braking. After launching one I set the other beside the tracks to have a similar hard pack surface to be totally fair. Without any further ado here or my results!!!

Kymco MXU450i = 0-60KPH in 6.33 seconds.
Yamaha Grizzly = 0-60KPH in 7.47 seconds.

To be honest with everybody I would have never thought the Kymco was that much faster. Riding them back to back the Kymco accelerates very hard out of the hole and has a very strong midrange. Even wanted try and fish tail a little!! With the Grizzly I was becoming glad at the end I had headed toward the yard. I slide to a stop 2 feet from the landscape timbers at the end of my driveway stopping. The kymco easily tripped the 60 kph timer and stopped easily with many feet left over and easy braking.

Some may wonder the point of my post. Well this year I intend to do a touch of modding to both. Now I have a decent idea of what they will do. Can retest and then mod and test again to see what gains. I posted this just for entertainment of our Kymco crowd!!!
