The early 78's used up the stock of '77 optional arms.  That arm has the mount for the short brake stay arm.  The later 78's did not have that mount, because 78's have a floating rear brake.

Then its a 77 alloy arm legal for pre 78.

Talk to someone about it before you buy it as in Oz it is still not established that the RM125B optional arm is legal as no one ever saw one in use. Which is most likely why many early RM125C bikes came with the rear brake lug included.

In fact it has been understood by many that it is not legal at Oz national level. You can not use the parts book as evidence. Certainly welding a lug on to an RM125C arm would make the part not legal in OZ. Not interested in a debate as it has been done to death several times. Just thought I would mention it in case someone was going to fork out money for it.

Ted will now come in at this point I assume ;D

The only one I ever saw back then was Gunter on what appeared to be a RM125B with a C arm, rear hub and full floater rear brake late in '77. Which given his Suzuki status could have been pre-production parts I gues.

I am sure Ted would be interested in any evidence that can be used to support the 'B' option alloy swingarm. Doesn't make any difference to me either way.

Unfortunately i don't have any pics to back it up but my mate bought one from Phil Thew Suzuki for his B in '77. Noel Harker was the salesman there and he's into the VMX scene also and can back it up but again we don't have anything on paper, just the word of a couple of hard core mxers who were there in the 70's.. ;)

I got an idea ,might be a bit far fetched , but how about just look at it ? Then decide well does it look like someone made it in their backyard or is it a modern Novation arm like lots of others are using or does it look like a genuine Suzuki part ?

It not only looks like a genuine Suzuki part, it has a Suzuki part # 61100-41870-019 REAR SWINGING ARM SET.       November 1976

If it is deemed illegal surely these optional part numbers published November 1976 are also illegal :

09825-00002        LEVER, tire

09821-00004        INFLATOR, air

09826-00001.       TOOL, tube repairing

99000-33010         GASKET, liquid

99000-32040.        CEMENT, thread

99000-25030.        GREASE, super

99000-10105-019.  PAINT. ( BLACK )

99000-10105-163.  PAINT ( PHLOLINA. YELLOW )

11400-41811.        GASKET SET

11400-41850.        GASKET SET

11400-41891.        GASKET SET

After typing this out I thought why not order these optional parts from Suzuki and if any or all of them are available or were available Pre 78 and seeing as they are out of the same parts catalogue as the alloy arm then surely the arm was available for sale as well. I have been informed by MA that a eligible part only has to be available for purchase, not necessarily purchased.

yes Ted the suzuki tyre levers are illegal if you show up with them at a meeting you will be escorted off the site ::) and don't even think of repairing a flat tyre with the tube repair tool FFS what are you thinking ;D

As far as the swingarm goes JohhnyO said they he someone that bought one in '77. Now if you got a statutory declaration from that person and also the dealer who is still around signed a Stat Dec confirming that purchase it may just be enough?

You are not listening, Now pay attention.....For a part to be legal it only has to " BE AVAILABLE FOR PURCHASE" so JohnnyO's mates shopper docket is not required. He'll, they even let Montessas in and who bought them?  ;D

Ted are you sure you are not a Minister in the Gillard Government ::) you handle thing in such an organised and orderly fashion ;). Firstly you have to prove that it was available to buy and that is the whole issue with this swingarm thing  ::).

1) The fact that early RM125Cs had what appears to be optional RM125B arms proves they didn't sell them otherwise they wouldn't have them. It does not however prove that they were actually available to the general public to buy
2) It is also possible that RM125Cs were to have non-floating rear brakes until production had already started who is to know.
3) Someone saying they think they bought one or someone knows someone that could have had one just doesn't cut it.
