Background and development
Since their arrival in Grand Prix racing in 1959, the Honda team had impressed everyone with their commitment and professionalism. Buoyed by the team's success in the 1961 125cc World Championship, with booming sales of Honda's 50cc Super Cub road bike and the Sports Cub C110, and the announcement by the Fédération Internationale Motocycliste of a 50cc World Championship for motorcycles for 1962, it was perhaps inevitable that the team would be keen to participate in this new category.Design
The engine was an advanced four-stroke single-cylinder (and was sometimes described as a shrunken half of an RC145). The cylinder axis was inclined at 35°. Two overhead camshafts in a four-valve head were driven by spur gears. The engine was said to produce 9.5 bhp at 14,000 rpm. TheRacing history
The RC110 was displayed at the 1961 Tokyo Motor show in November 1961 and made its GP début at the 1962 Spanish GP in Barcelona by which time the number of gears had been increased to six. Despite this the bikes were easily out-gunned by the two-stroke opposition and this was Honda's first serious defeat since 1960. A massive effort at the factory meant that for the French GP just one week later, the bikes were fitted with eight gears and then, another three weeks after that, for the IOM GP two completely new bikes arrived, now revving up to 17,000 and fitted with nine-speed gearboxes. Despite all this effort, Honda's 50cc machines still could not match the success of their larger brethren. Averaging over 120 km/h around the TT course, Luigi Taveri and Tommy Robb could still only manage second and third places and although on a damp track at the Finnish GP, Luigi Taveri did manage to grab a single victory, overall the 1962 50cc season was a humiliation for the Honda team.World Championship results table
(Honda CR110
In contrast to the RC110, Honda developed a lower powered production version, the Honda CR110 Cub Racer. Aimed at the privateer rider for club and national status events, the CR110 proved more successful than the works machine and about 220 are said to have been sold worldwide. There were two versions, a five speed road machine with lights and silencers producing 7 hp at 12,700 rpm and the racing version with eight gears and 8.5 hp at 13,500 rpm.Notes
