The short- lived Heldun racers from Birmingham competed in the 67 and 68 Isle of Man TT races.
In 67 driver P.J. Walsh failed to finish, and in 68, Doug Cash too, experienced a dnf.
The Heldun Hawk production racer had a 5- speed Sachs engine, and 18 x 2.50 tires.
The street version, the Heldun Hurricane, had smaller 17inch wheels and could be outfitted with a racekit, to get the looks of the Hawk.
