(not mine)
Pretty rare. This may be the same one I saw locally about 10-12 years ago

1986 Yamaha RZ250 - $8000 (mission viejo)
1986 Yamaha RZ250 clean title, runs great, low miles (2500). Rare bike never imported to USA, came from Australia, s/n 21, no dents, never crashed or dropped. Too many bikes, my loss is your gain, you will not see another one of these bikes, it is the only one I have ever seen or know of. Up gradable to a RZ 350 displacement by swapping top end with an RZ350. Parts and extra spares available separately. No low ball offers, you must come see bike, I do not talk price over the phone. Thanks for looking.
