I was seriously considering getting one of the old 250's, With such high redlines they must sound like an F1 car. I'd imagine it's hard to find one of any kind of condition let alone a nice one though.

They aren't particularly uncommon over here in Australia. They're a fun little bike to ride but I'd never take one over a 400.

There's one on ebay.

Are the old ones the same frame as the 400, or are they smaller?

no idea but that looks like a H model 400.
