Did anybody here buy a RM in 75?

I bought a RM 125 in March 1975, Didn't make me a champion, but I did learn alot ....It was my 1st bike!!!!

Didn't make me a champion, but it did help me move up from Intermediate to Expert. The old TM125 was a fun ride, but you could not make it run with a FMF or DG CR125 - the RM125S on the other hand worked a treat.

I was a little too young to buy a new '75 RM.....but I can remember drooling on them in the showroom with my Dad.

Low pipes look so cool!!

Was the 75' RM that much faster than the 74' TM125?

The suspension was much better.

Joe Abbate in New Jersey had one of his restored RM125's featured in a museum type setting in Rockefeller Center.

From his site: I have also tried my best to make it as informative as possible, so that you, the reader, can get a greater understanding of what you may want and expect from your next restoration. Several motorcycles that I have restored have been show winners and one (1975RM125M) was recently chosen to represent the “Long Travel Era in Motocross” where it was on display in the lobby of Rockefeller Center during the New York City Motorcycle Exhibit. I felt a sense of accomplishment, yet more so humility, that my bike was selected to appear on the floor with motorcycles of well known custom bike builders, along with rare Japanese and European factory racers chosen from collections all over the World.[attachment=0:fbc64]RM125.jpg[/attachment:fbc64]

There were 2 models of the downpipe RM125 - the M model, which was pretty much a souped up TM125 with laid down shocks - I think they were like 3.5 hp better than the TM125. Then there was the RM125S - this had a competely different build and was about another 3.5 hp up from the M model.

Really??? I had a 75 and I don't recall this? What were the other differences??

I can't remember exactly. Back then I only worked on my own bikes and the mechanics looked after my race and practice bikes. I do remember the M had a 4 bolt head and the S was 6. I also think the pipe on the M was a twin-wall and the S was a lot lighter in construction. The forks on the S had 1/2" more travel and worked better too if my fading memory is still working.

I gave one of my old Suzuki mechanics a call.


Bigger carb
Rolled cone pipe
High compression head
New CDI - 750 rpm higher rev
Different internal ratios
Revised fork internals
Revised shock valving

I had one, but also don't recall two different models. Luved the bike, while underpowered and down a gear to the mighty 6-speed Elsy, it handled pretty good for it's day. That was until the Elsinore killer 77 RM125B came out!

there were not two different rm 125's available in the states that year. no way.

He's in Australia though. I do not remember two bikes in the states.....for 75 OR for 76, as his website says.

There was not 2 different RMs in '75 but there was a factory hop up kit that was available(aprox. $200-300) which consisted of a different cylinder,bigger carb & a pipe(which looked the same but had either a shorter or longer rear section) & I might be missing an item but that was it in the states.

Yes way

The M came out as an interim while we were doing pre production testing on the S. I think they were available for about a month or two and then the S took over. Basically we were shitting bottom ends and shredding gears on the test mules.

That sounds like the 'works' kit for the TM to me - we used to sell them at a ratio of about 1 to every 2nd TM125 that went out the door. I do believe a kit was available for the RM125M that was a head, pipe & carb.

You could be right but I have a mag around here that tests both the stocker & the kitted bike.If I have time & find it I'll post what it says.Either way I'd have to strongly disagree as far as two different models being offered in the states.I've heard of the "S" model in Austrialia but trust me I've never heard of or seen a collector who has the so called "S" model here stateside.
I did have a kitted "M" model a while back but currently I just have a stocker.
Either way it was a helluva a step up by Suzuki and was the precursor to their 125 class domination for the mid 70s to early 80s.

Shadow Glen track?

I rode one of the first mono shocks back in the days. It was an RM. I rode for California cycles as did my brother mike Musson.

I have a 75 M model with ( I believe) the S kit Carb... It looks "S" in style and size.. but CDi is in front of the airbox, not up on the steering head where I heard they are on an "S". I put a cone pipe on it. It had a rotted out stocker.

The 1975 RM 125 was sold in the states. Not sure the S model was ever sent here due to the 76 Rm 125 A model.
They did sell a hop up kit with a bigger carb, pipe, head and airbox. Not sure if the ignition changed, but kit included some brackets to position the CDI over the top of the airbox.

There is not much in common between TM/RM. Forks were increased to 35 MM from the "light weight" 30 MM. Bigger front hub, cushionless rear hub. Rear frame look disappeared and the seat looked more like Rogers. Engine had wider stud pattern to accommodate the new cylinder. Bigger carb and great looking pipe wet along with it. Rear suspension goes without saying. Oil pump was removed, but the cavity still was there. Some BNG's and off you went.

These motors will bolt into a TM frame. Don't think Ahrma will let you run them. They had better suspension than the CR 125 stock, but by then there were not too many stock Honda's running. Motors were of a different nature. Honda was all about top end, RM was better power band.

And don't forget, the Mono Shock was hitting the tracks as well.

Good time to be 16 and a 125 MX racer. Slow as I was, I got passed by most brands of bikes!

The S model was a kit as I remember, Then was Standard equipment on mid year 1975 RM125's

I remember going to the Suzi dealer and thinking wow I can stick by head in there has to be a foot gap between the rear tire and fender. Great times.
