nah never used to race, only did it for fun. but had karts for years.
still prefer 100c myself,sold my last one last year CRG DAYTONNA HERRON, with an ITAL mv21 tuned.

but if i was ever to buy again it would be a max, mainly just cos its easlier to go on your own.
rich pon used to race when he was younger, he has jenson buttons old kart.
