Gearing tweak, 74 on a flat/level road, 77mph in a little dip in the road with my latest gear swap 17-32 @ 9050 rpm in 5th!! Fastest speed I have ever been on a CT70. The little dip adds 3mph on any of my modified CT70's. Be it a 108, 124 or a 140cc. I actually ride these things ALOT!🤣 1514 miles since Dec 14th 2022. If you can't pull the specified red line for the engine in top gear , you ain't going fast.. Mine is rated @ 18 rwhp @ 9500 max.
