Background
The Norton Dominator 99 was made in Birmingham between 1956 and 1962. Powered by a 600cc vertical twin engine, a basic model was offered alongside the De Luxe and the Sports Special; the former was a semi-enclosed touring motorcycle while the latter was a high-performance variant capable of 108mph.
Designed to take the fight to the Triumph Speed Twin, it was designed by Bert Hopwood, the same chap who’d worked on the bike it was designed to beat when he was at Triumph…
With 31bhp on offer and a wet weight of just over 410lbs/186kgs, the Dominator 99 returned a top speed of 114mph after passing the quarter-mile marker in 14.61 seconds when tested by Cycle magazine.
