1963 Triumph Bonneville
A WHOLE NEW MOTORCYCLE! The 1963 Triumph Bonneville was essentially a brand-new bike. Not quite designed from a clean slate, but nearly every part was new and/or improved.

1983 Triumph Bonneville
ABOVE: 1983 Triumph Bonneville TSX, factory custom in Gypsy Red. 8-VALVE HEAD As close as they were to the brink of extinction, the optimists at the Meriden Co-operative still believed it could be turned around, and the only way was through product.
