I'm wanting to build a pitbike for myself and don't know where to start. I have a friend that has a CRF50 that has a lot of mods (bigger frame, longer swing arm, bigger forks, taller bars ect). I'm a little taller than he is and feel a little cramped still on his bike plus his frame has a lot of rake in the forks and it makes the bike handle weird. I was thinking the bigger tire of the 70 might work better. Also is the 70 stock frame bigger?
