Why spend your money? Scooter in stock form just fine----want more performance=get different/bigger bike or scooter....probably cheaper in the long run and maybe more reliable.
Thanks for sharing this same sentiment every time someone asks about performance parts.
Personally, I know a lot of people who have used the J Costa variator on a lot of different bikes. The best review I heard, from a friend who has done a lot of engines and scooter builds over the years is that it's great until it isn't. When he first put it in a Vespa S150, he told me it was the best variator ever made. When it came apart and ate the teeth on the crankshaft, he didn't like it anymore. This seems to be a common sentiment among J Costa users.
The "I installed the part and rode it around the block and it's great," reviews on the internet are not the best determination of how well something really does.
If only there was a company that made performance parts and had direct experience racing the Kymco Downtown....
Any prominent companies come up when you google Kymco Downtown Racing?
