Riley 10. (1909-14)

The Riley 10 was launched in 1909 as a scaled down version of the 12/18, where the engine was a smaller V Twin, but crucially still front mounted unlike the smaller 9hp model. The radiator was again elliptical, providing a curved bonnet, behind which sat a 2 seater 'Torpedo' body. Windscreen and hood were not fitted to all early cars, but were at least optional as the years went by, and the body became somewhat better styled than the rather basic outline of the earliest cars. There was also, for an extra £20, a speed model available, which proved itself in a number of competition events in 1909/10.
From 1911, this was the smallest model of the Riley range, as the older 9hp was dropped. The 10hp was also dropped at the outbreak of war, partly due to the war, but also because a new 10hp model was ready for launch.
