The optional 'B' alloy swingarm has a brake-stay lug half way up the underside of the right side on the arm. The 'C' swingarms had a full-floating rear brake where the brake-stay arm went all the way up to the frame.

Early production & pre-production C models that were made for promotional use and some brochures in 1977 had the left over optional B swingarms fitted.

Even though the swingarm is in the printed & dated 1977 parts catalogue (which I have a copy of) and even though there are many other aftermarket alloy swingarms passed as legal for the '77 RM125, some officials will not pass it as they say there is not enough proof.

I have seen a pic from someone on this forum (can't remember who) of Anthony Gunter, taken in 77, using the optional arm on a B model.  You will have to dig up more proof; this will make optional B arm accepted.

It's ridiculous that optional alloy swingarm is not approved for pre '78 racing, it's in black and white in the '77 parts book which was printed early 1977! How much proof do they need?

Yes and he also has a floating rear brake fitted.
