did we ever come to a conclusion about the alloy swingarm for the pre'78 RM125's

[DR]

Thanks Johnny (and anyone else who agree's) I wasn't overly concerned but its got my hackles up a little now so I'll follow through. We know for certain they existed so now all we need is photographic proof showing 1 fitted to a B in 1977 since the part listing is not valid no matter what the date of print. I am sure Mr A. Gunter used these arms during his titles assult in this era, the pic below proves my theory that the 250/370 aluminium arms were available for gun riders who had a little factory backing or the right connections with Suzuki Australia. 

The picture below taken at Adelaide in 1977..now we just need a pic of the 125B he won the title on that year and I reckon we'll have all the proof needed. On a side note, this 'is/was' our homegrown MX scene and not the US and not factory bikes!



to worry about the bike losing it's pre'78 personality, I think this picture below also points out it doesn't change the bikes appearance as much as people would think. It certainly doesn't look out of era on what will be my poor mans  'Gaston Replica'

mmm..not particularly clear is it ..could be my failing eyesight too could be any arm I suppose. I also suppose a quick email to Mr Tony Gunter may be on the agenda. I know last time I asked a question of Anthony I didn't quite get the reply I was hoping for so maybe 2nd time around he'll do betterer

Where was that from Brent?
I wonder if this mysterious & probably very old by now Jeff Keen still has the original photo's?

[motomaniac]

its from MotocrossAction mag nov 1977.

i will try and scan a bit better.

and how would you go about finding him after so long even if he did still exist!

[motomaniac]

is this better ?

[asasin]

You already know the answer to that John -NO!

Maybe getting close to a YES

Looks like "the Grunt" is running a mean sized torque arm....and golly gee...a "B" optional swingarm with a floating rear brake set-up!

[DR]

  it really does look like the optional arm on the Grunt's bike doesn't it I'd say that's the 250 again. I've seen my swingarm from that angle (don't ask! ) and it looks oh so similar if not the same with the big ridge on the inside edges. And yes, floating brakes too I see Monaro..that ones really a non issue though as my F11 from '73 has full floating rear brakes standard so it was old school technology (possibly useless theory) by 1977 and near everyone who was anyone in MX had it fabricated and in use by '75 seems we are getting closer. Thanks! I don't feel quite so bad now they still maybe outlawed for pre'78 but we have proven existance

[DR]

just noticed, you can see the brake stay mount still attached under the arm. Near bet my left nut that has to be a genuine optional arm for the 250, the option was offered in the US for the 250C which had the steel arm before the C2 was ever released so they did exist for the big bores also I'd say. I'm going to send Mr Gunter an email and ask, I just hope if it is the real deal that he may also have a decent picture of his 125B as that is a local bike, on local tracks and in the correct era. I can't see any possible reason it would fail as being acceptable proof of existance

Could be a bit like the famous RGV 'kit' manual, that was full of fruity bits with official part numbers, problem was  only a select few knew that parts existed to take your RGV to F3 spec were available back in the day. Suzuki Aust denied all knowledge of course as 250cc Production was all the rage . Nobody ever knew why the press fleet went like rockets and the showroom bikes a little dull.  

[DR]

mmm..does sound a little familiar and why would they want to make it common knowledge. Being genuine parts they were never advertised and back in the day to see the parts books or fiche in detail was like asking for an appointment with God

The 3 captures below I've just taken from dvd footage of the 1976/77 Toowoomba Mountain Man meeting. The date cannot be disputed but this time it's on the RM370
