Yup. Most pit bikes are based off the smaller dirt bikes (crf50 is by far the most popular). Engine sizes can vary greatly with all the new Chinese engines and big bore top end kits. I am lucky and my atc 70 uses the same engine bolt pattern so these engines interchange with little mods. There is even a new Chinese engine with the Honda lower and a Kawasaki 110 style top end bored and stroked to 160cc's
!!!! I might be going with the electric start 138cc Lifan motor.
Yep,
That's what a couple friends on mine have... one has the 140 so the other had to out-do him and get the 160.
The guy with the 160 tells me one day "Take this for a ride and tell me what's wrong with the handling" I take it for a quick blast, lay her into a few berms and tell him there isn't enough rake in the front end. A few minutes later we are pulling off the tank and cutting a section out of the top frame tube. A little bending, some welding and some paint and she handles like a dream now.
