the off-road tradition of its forebear, though now with a larger and more
powerful engine from the Thunderbird. The first examples were called the TR6
Trophy-bird to reference the names of
.
The new TR6 used the Delta alloy cylinder head with a cast
iron barrel, it had an 8.5:1 compression ratio and was capable of 42 bhp.

and most riders would fit knobby tires, thicker seats (suspension travel
wasnt ideal), and open exhaust pipes.
