My last bike in NH was a chopped 71 Bonneville. My best friend bought it new in Conn & no one ever had a wrench on it but me! It makes a BIG difference when only someone that knows Triumphs is the only one that ever works on them! After I got done with the engine & chopping , I painted it Black Imron(sp?) with Kelly Green pin stripping. It was my Street Bike & it turned 12.2 in the 1/4. Not fast now but this was the '60s.

P.S. That's also with an 8" over Ft End.
P.P.S. That's also when a Big back tire was a 5.10 X 16 Goodyear with a Harley Rim , custom spocked(sp)to a Triumph hub. Wider than that & the tire would rub on the chain! (These changes were submitted by Rube Goldberg)
