Phil Read
In the beginning, Taglioni's Ducati chassis was used. It had a single Lockheed front disc brake and a twin leading shoe Fontana rear drum brake. Dry weight was 135 kg, and it had 18in rims front and rear with 3.00 and 3.25 tyres. Wheelbase was 1430 mm. In June 1971, Phil Read tested the 500 cc bike with the Seeley frame, and pronounced it the better of the two. The frame was then fitted to Spaggiari's bike as well. It was raced in 1972 by Bruno Spaggiari, Ermanno Guliano, and Phil Read.
