Question 125m specs

[matt86200x]

I have a frame and front end from a 84 125m. My question is will a orion 125 pit bike motor bolt on to the 125m frame?

I do not believe any pit bike motor will be "bolt in". Just about every pit bike engine I've seen is based on the ATC70 variant of engine. The 125m uses a ATC90 style engine. There are lots of old bikes that used the ATC90 style engine but very few new bikes.

I'm sure with a little bit of work you could make your pit bike engine fit the 125m. I know several people have done it before you.

it can be done but its not a direct bolt in my 125m uses one bolt on the trailing end and one bolt and bracket up front on the head and the pit bikes/ 70 motors us 2 trailing end bolt to attach the motor i believe
