I will check with my buddy. I know he has alot of old suzuki stuff. He helped me get my 79 rm125 running again.

Its been 30 years, but I do believe the M model used the same bottom end as the TM125.

I think you are right, I think the only difference was the head. I am looking for more people to agree with us. Thanks Motoman.

Suzuki was in a scramble in 1975 trying to catch up to the competion. They changed models during the year. Both 1975 RM models are rare.

The cylinder is different in that they added a couple of more small transfer ports. The ads at the time called it a 6 port cylinder if I remember right. However I think they feed them through the same size bottom openings as the TM. I can tell you that the 1976 RM125A was a totally new bike and the only thing I think it shared with the M was the front wheel. I had an M, but I only kept it about 2 months and then jumped to the open class. Fun little bike though. Jeff

there was some manufacturers playing catch up to Honda.the CR125 had a nice model run with that bike.if the suspension was only a little better.motor wise they dominated pretty well.unlike the 250 the 125 had a good run.the 75 and 76 250's bikes hurt royally in the suspension department,compared with yamaha and suzuki.they did make enough power to compete though.
