1948 TRIUMPH SPEED TWIN DESIGN

SUPER RARE VINTAGE 5T SPEED TWIN

HIGHLY DESIRABLE AND COLLECTABLE

NICEST ONE IN CANADA

BEAUTIFULLY RESTORED TO FACTORY SPECIFICATIONS

HOP ON AND GO - RUNS BEAUTIFULLY

AMAZING ATTENTION TO DETAIL IN ITS RESTORATION


The 500cc twin retained its cast iron cylinder block and head, and was fed by a single Amal carburetor. It was of non-unit construction, with the timing gear on the right, and the primary chain and clutch on the left, as usual. The 4-speed gearbox shifted with the right foot. Triumph continued to use it’s tried-and-true rigid frame, but offered a sprung rear hub as an option. The sprung hub used radially-positioned springs inside it to cushion the bumps.  The front end now had Triumph’s own telescopic forks with hydraulic damping.
