It's getting harder and harder to find a pre-unit Triumph lately. It's been more than 2 years since we bought the last pre-unit Triumph as our inventory and this is the one we picked up from San Francisco last Saturday. Unfortunately, this is not matching numbers bike, but the previous owner did top end job replaced some new parts include oil pump and the Amal carburetor for this 1957 Triumph TR6. Starts easy, runs strong and very fun to ride.
