Famous English motorcycle rider Howard R.. Davies, having won the Tourist Trophy in 1921 year (riding an AJS motorcycle with a capacity of 350 cm3 won the class 500 – senior), decided in 1924 year to start producing their own motorcycles. In this endeavor, he was assisted by the renowned Massey technician, who already had experience in the production of Massey-Arran motorcycles. The first HRD motorcycles were assembled in a basement workshop in Wolverhampton. Parts and components from other manufacturers were used, e.g: JAP engine 500 cm3, Burman three-speed gearbox, etc., but also did not shy away from their own solutions. Originally constructed:. in. fuel tank. Previously used fuel tanks were placed between the upper tubes of the frame. Designed by Davies, the so-called. saddle tank, "He was sitting” on the top tube and encircled it on both sides, going down symmetrically. This gave the bike a more modern silhouette, and also allowed the construction of tanks with a greater capacity.
W 1929 Phil Vincent took over HRD, which its new models with Villiers engines, Blackburne, Python and JAP equipped with "soft” rear wheel suspension (according to own patent). From 1934 In the year, the company also produced its own engines, of a capacity 499 cm3, to your motorbikes. W 1937 In the year, the liter engines used in the famous models, i.e.. Rapid, Knight, Black Shadow, Black Prince, Black Lightning i inne.
The Rapid motorcycle had a V-twin engine with overhead valves (OHV) of a capacity 996 cm3 and power 33 kW (45 KM) at 5300 rpm. The four-speed gearbox was the load-bearing part of the modern central frame. The vehicle has a friction clutch, disc, in which the clamping force of the disc was the result of the action of springs and the centrifugal force, from spinning weights, attached around the circumference of the pressure ring (the so-called. system półodśrodkowy). During the modernization, carried out in 1946 year, the Rapid motorcycle is equipped with a telescopic duralumin front fork with hydraulic shock absorbers. As the name Rapid suggests, it was a very fast vehicle - the maximum speed was 176 km/h.
