Suzuki RG250 Yamagamma RZ350 Track Bike Resto Project Historic Road Bike in Sydney, NSW | eBay

would go like stink, but an acquired tase in the looks dept. Would be an excellent in-expensive track bike for a beginner.
I prefer the lc at the bottom of the link, that was also viewed. What's weird is that I have seen both a mars bar and a blue lc come up for sale recently.
I can only remember white with red 250 or blue stripes 350 in Australia.

I know the yamagama and the seller, there is enough parts to make it look pretty much standard again if you wanted.
