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.

Don't think so.

I don't think it would ever be specifically mentioned. As long as you can prove a part is legal if protested you're ok.

They can't start printing rulebooks listing every legal part for every make and model.

It's not the optional 77 arm then but a 78 arm. Good luck!

Here is the proof.

RM 125 M and S

(http://i582.photobucket.com/albums/ss270/ted84photos/037-1.jpg)

RM 125 A

(http://i582.photobucket.com/albums/ss270/ted84photos/034-1.jpg)

(http://i582.photobucket.com/albums/ss270/ted84photos/035-2.jpg)

RM 125 B

(http://i582.photobucket.com/albums/ss270/ted84photos/032-2.jpg)

(http://i582.photobucket.com/albums/ss270/ted84photos/033-2.jpg)

RM 125 C

(http://i582.photobucket.com/albums/ss270/ted84photos/030-1.jpg)

(http://i582.photobucket.com/albums/ss270/ted84photos/031-2.jpg)


As you can see in the photos the RM 125 B uses the same Torque Link as the RM 125 M, S and A models.
It does not use the 1978 RM 125 C Torque Link whick is a floating brake setup.

Looking at the photo of the optional aluminium swingarm it does not list a Torque Link to make the option viable. One could only assume that the standard RM 125 B Torque Link would bolt to the swingarm as per standard steel swingarm. 

How anybody could think that this Suzuki aluminium swingarm is not period correct is beyond me.
