2 strokes 50cc specifically designed to perform at 8-9k rpm pushing them to 12-14k ist to bad with a 74cc kit. ive had a 74cc 2t and it would do about 55 but gearing was my downfall downhill i could go 60 and its the stock crank. i had roughly 2000 miles on it doing the same thing wot rides and my engines still fine. and the bearings are still great. trying to compare a 4t to a 2t is like comapring a white guy to usaine bolt..JS
