Title: Gear Change Project
Post by: agilebda on December 27, 2013, 07:12:51 AM
Hello guys and Happy Holidays to you all.

I was pondering about installing the Downtown gears in my GTI being that it's a slightly different ratio. Hopefully will gain more speeds. After all, The Downtown is overall a few mph faster that it's sister bike the GTI due to the gear ratio.

What are your thoughts on this?

  I would be interested in seeing the results. One other thing to consider. The DT rear tire is a smaller diameter than the GT, so it might not be just the gear ratio that impacts the speed. I believe there is a slight difference in the motor also. I think I would experiment with the cvt first. I put lighter sliders in mine and improved acceleration which is what I wanted. I can still cruise at 70-75 which is fine for me.

with wind resistance,  wt., of scooter your wt., and power available, you wont see much change,. try bigger tire at the rear, if you can find one, remove wind shield, lay down on scoot, and try for top speed , I did it once and just hit 90 mph, on my down town,. I now can brag it will do 90,. but now it has every thing on and will barely do 85 mph, regular riding I hardly ever go over 65 mph. riding in the country side , 50 to 60 mph,.easy riding is more fun,  and I want to enjoy it till I hit ninety years,. 9 years and three months to go, happy trails to all,  and a happy new year

Hello Mike. No difference in the motor at all. I asked a local Kymco Mechanic and all is the same except for the transmission ratio. The smaller wheel requires slightly bigger gears. Just slightly.
Lighten up on the rollers, and you should have awesome top end.

Also I just found out that Malossi produces a 400cc kit for the Downtown and the GTI. I was waiting for this to happen.
