1975 Suzuki year M

Suzuki introduced the RM series of models in 1975, these the TM models. The range quicly out from 50 to 400cc and became successful. A few years later the Floater swingarm was introduced and engines came along in — and the developement of the RM models even today.

The first version of the RM125 had downpipe, the pipe placed under the The TM125 was discontinued and instead the RM125. When tested the competition in the US market the RM125 was not powerful enough to compete the Honda CR, kawasaki KX and Yamaha YZ and had to be quickly modified before mid 1975.

The model name to the revisited was RM125S.

To make the bike Suzuki did some interesting in the following areas of the engine: reworked the porting of the cylinder massively, all ports were significantly and they appeared to been finished by hand viewing the cylinder. The new hand exhaust pipe for the RM125S was larger in diameter and made of rolled steel pieces together, not stamped with two folded seams like the M The stinger bulb was also on at the end of a slim diameter pipe a stiffener rib above and below it to cracking where this met the end of the expansion chamber.

The headpipe also still the OEM chrome exhaust collar, but now extra L shaped pieces under the bolt heads, ‘ears’ each held one end of the that kept the pipe in to the cylinder head.

The pistons had two holes drilled into it to cool the thin exhaust bridge section as the new exhaust was now quite wide, the head material was also slightly

The S models Mikuni carburettor was quite larger and didn’t the tall top cap as the M model, and the carburettor rubber/alloy pipe was also and carried an adapter plate. The new had increased jetting values and a needle valve orifice three extra angular holes to allow fuel to the lower needle valve into the bigger float

The newer and bigger CDI unit for the S was now mounted onto the front of the headtube with a bracket of in front of the aircleaner case as the M, and finally the air cleaner case was to accomodate a bigger rubber boot. To let the owner know had bought an ‘S’ model, the tank had a decal affixed below the filler opening said RM125S.

As noted, the output went up to 26hp, and was enough to allow it to run with the CR, KX and YZ that were beating the M The S model only lasted for four months (later in countries, it was sold as a 1976 at least in Finland) as the new A model was tested for ’76 and the S therefore sold in large quantities.

can see quite clearly the CDI box mounted on the column on the bike and how the hand pipe looked as well as the non cap carb. The small dents in the bulb were there I bought the bike, but the bigger in the pipe lower down is for the starter to pass when Allan says.
