There is a nice one for sale locally, is this a reasonably good bike? I do not know much about triumphs. has a boyer etc. Would make a good GIRO bike? Pretty sure Pete T. rode one in a Giro a year back or so.
Pete has ridden his 200cc Tiger Cub for the past several years. The one you are looking at is the cubs successor. The cub is a sloper engine, while the later one is vertical. I believe the Triumph and BSA Starfire were the same bike. The BSA kind of looks like a mini Victor 441
I think I have a contemporary test of the Triumph and BSA that I would be happy to fax to you if you like.
I have ridden around on a bsa starfire 250. Fun little bike. There were a bunch of the bsa/ tri 250's at the spring giro. Looks like a fun bike. Joe has one, I have been bugging him to get it going for the Giro....
