The Aprilia RS150 is a supersport in much the vein of the Yamaha YZF-R15. It is derived from the RS125, a 125cc supersport that is popular in the European market. However, the 150 has, as the name suggests, a 150cc engine. It will have four valves, fuel injection and liquid cooling and generate around 18bhp. The concept on display at the Auto Expo also had a quickshifter for the six-speed gearbox, but we do not expect this to make it to production to save costs. Also on the chopping block are the upside down front forks, radially mounted, fixed brake callipers, and ABS. The RS150 should debut sometime in 2019 and will compete with the Yamaha YZF-R15 V3 and the KTM RC200.
