I'd like to find a new 12mm rear axle for my MAR, it's only slightly bent but the thread is a bit sad. Haven't seen any available on the Ossa websites I know of. Ross Grimsey mentioned something about Suzuki TS 185 axles maybe fitting. Anyone had any experience finding something that fits?

Hello, Have successfully Sealed an Ossa MAR and Ossa Super Pioneer Petrol Tanks using the Caswell Sealer products.
Go to http://www.caswellplating.com.au/store
Like Many products, if you FOLLOW the INSTRUCTIONS EXACTLY, you will get the desired result.
We did and it worked,
Ron S

Thanks Ron, I did buy the Caswell Tank Sealer kit but never got to apply it due to my own stupidity. I followed their instructions regarding acetone and Tek screws to clean and roughen the inside of the tank, foolishly I left some acetone in the tank overnight and it ate through the fibreglass resin. Now my tank leaks like a sieve(never refitted it to bike) as it was obvious the damage I'd done. Awaiting a new tank from Steve Eastham in Vic. My Caswell kit sits on the workbench unused.

Found this on ebay from NZ for anyone chasing a rear axle.

I used a Yamaha CT1 rear axle on my Ossa, Think i had to change the wheel bearings to suit the thicker axle, Didnt help much, they still bent !
