Hi all - long time lurker - saying g'day.
Its time to start digging into my broken RM collection and build a bike from the rubble. We have a great track in Kal and at last years arena-cross a few lads took to the dirt on their vintage rides. Looked great and stirred a lot of interest so my brother and I are building a bikes in the hope of getting a few similar events happening in Kal. He's started a YZ400F and mine will be the trusty RM125.
I have what I'm told is an RM125s (incomplete) and another RM125A (in pieces). I'm hoping to bleed the forum brains trust of a little knowledge so I can identify my starting point.
The 125S is missing its tank - which I've been led to believe is steel with an offset filler. Frame and engine are complete with a DG head and downpipe. This is the bike on ebay a few months back in Melbourne that was mentioned here.
The 125a was recently purchased in Perth .. also off eBay. Engine is in pieces and missing some minor stuff like carb etc. Now... I was under the impression the A's had an aluminium tank but this one has a little corrosion inside so its got me pondering if its steel? If it is and is the same as the S tank then the 75s will go ahead. If not then maybe the 76a will be built.
Can anyone give me a few hints on how to identify what model the bikes are? I believe there's also some differences in forks? Anything else I should be looking for? Is there a difference in the S and A tanks (or am I barking up the wrong tree here).
Was there much difference in the 75 / 76 engine? Is the DG head interchangeable?
Appreciate the help and will throw some pics up when I can. They're not much to look at for now, but the plan is to spend too much money, drink too much beer, and build a presentable / useable bike for track days.
Like everyone I'm also on the lookout for parts for these bikes so feel free to drop me a line if your cleaning the shed. Happy to pay good money for good parts (or bikes) and distance isn't an issue.
Cheers,
Steve.

RM125A and RM125S are totally different machines in design and configuration
First off the "S" tank is steel with a central filler (same as 75 TM125) the "A" tank is aluminium
Engines are totally different with the "S" engine being the last 5 speed to be derived from the TS125 line (parts will interchange with 76 TS125 as the share the same cases) The "A" engine was a whle new design with six speed gearbox and reed valve HEADS WILL NOT INTERCHANGE as stud configuration is different.
Get your parts from your local suzuki dealer or http://vintage-suzuki.com/en/ , http://www.alpha-sports.com/suzuki_parts.htm
That RM125A you got from Perth had a RM125B front end on it by the way.

Thanks for the info guys.
So far I have:
RM125S with the correct engine. DG head. No tank and a C front end. So correct tank and forks will be "interesting" to find.
RM125A with the correct engine. Mostly complete but also with a B front end.
So... still not sure which one to build.... they both have pro's and cons so I guess I'll collect some parts and see which way fate spins me ;)
Will throw some pictures up when I can, and thanks for the help guys. Appreciate it.....

Snappy, All these tanks differ in some way, the TM125L has an offset filler, the TM125M centre filler but the same tank. the RM125M/S has a slightly different tank with a centre filler,If you compare pics youll see the seam is different.I'm pretty sure they are all interchangable. You do see them on US flebay from time to time.When I got my RMS it came with "A" forks which are basicly the same except one leg has no axle clamp.

Hi Snappy, happy to relieve you of the 125B forks if you can do without them.
Make me an offer I can't understand and I will get back to you.

No worries Suzi - will beat the feet to find a set that suits one of my bikes, and get in touch.
