Title: Trying to understand the vintage motorcycle rules
Post by: Upfield on October 04, 2019, 11:30:45 AM

Hi Guys & Girls,

New to the sport!

Building a 1957 "pre-unit" 1000cc Triumph Twin. Want to put it i a 1964 feather-bead frame.
What class dose this put me in, having difficulties figuring it all out, don't want to be a Bonneville and get told i'm i the wrong class.

Thanks
Darren

Darren, do you have a rules and records book?

I could go out to the shop to get mine, but if my memory serves me, vintage is 1956 and earlier

IIRC, unless you can document the changes between a legal (1955) engine and your engine (head casting, etc.), and argue successfully that they provide no advantage. Tatro has some later-but-legal parts on his post-56 KR.
