For your perusal, a Triumph Tiger that would make either a great frame-up restoration, or the beginnings of a great cafe racer project. It is relatively clean with (claimed) numbers matching.
Since this is mostly a stock bike (that exhaust looks very JCW), there isn’t a lot to say about what has been done to it. Cosmetically, it is a clean starting point for anything that might be done to it. I look at it as kind of a blank slate; what you do with it is up to you…

UPDATE TO THE UPDATE…
Paul has rescinded his thought about this bike not being a BSA. Apparently he looked at some of the details and decided that BSAs just look like Nortons, but are not actually Nortons!

UPDATE…
I got an email from my friend Paul over at TheMotoWorld.com telling me that this wasn’t a BSA. Hmmmm. Anyone else have an opinion on that?

Wow. This is a cool bike. The real deal it would seem. The only thing that is a bit out of place is the Yamaha 4 leading shoe brake, but I bet it stops that thing quickly.
Take a look at the description from the seller. He goes into some of the trick bits on the bike and in the motor. I think this BSA will make someone a wonderful half-century-old Sunday morning ride…
