These immortal motorcycles, powered by Triumph's magnificent
parallel-twin engine, are probably the most popular and sought after
classic bikes in the world--so for most owners and potential buyers the
question of originality is very important. The problem is, this
information can be hard to find, but in this book long-time Triumph
expert and author Steve Wilson provides the answers, backed up by
detailed colour photography of outstandingly original examples of Speed
Twins 1938-58, Tiger T100s 1939-58, Thunderbirds 1950-62, Tiger T110s
1953-61, and T120 Bonnevilles 1959-62. Mechanical components, frame,
suspension, brakes, electrics, wheels, metalwork, instruments, badging,
trim and colours and finishes are all covered, with some 300 specially
commissioned photographs pinpointing correct original equipment and
specification.
