yea them are cool.my sisters ex-boyfriend use to race them.in december they race on the daytona international speedway.idk what kind of motor he had but his went 115mph.some people even put 250 engines on them and make them shifter karts
yeah, my tony kart actually came with a shifter that mounts beside the steering wheel on one of the support tubes. Maybe if the 100cc motor gets boring, I'll throw a shifter motor on it
Mine don't have tuned pipes on them because of the class there set-up to run. Thats one of the rules, round 3 hole muffler. I think its to the keep costs down for everyone in the class.
