The RXV/SXV series are four-stroke, v-twin off-road (RXV) or dual sport supermoto (SXV) motorcycles produced by Aprilia since 2006. Both versions have either 449 cc (27.4 cu in) or 549 cc (33.5 cu in) engine sizes.
Frame/chassis
The RXV/SXV's frame is made of a combination of tubular steel and aluminum plates. The compact engine fits into the frame in such a way that the air filter sits on top of the engine, below the gas tank, rather than the more traditional under-the-seat location. This allows for a lower distribution of weight.
Engine
The RXV/SXV has a v-twin engine, and is one of the first off-road motorcycles to feature fuel injection. The 450 has a displacement of 449 cc, while the 550 has a displacement of 549 cc. Each engine has a single-overhead-cam and four valves per cylinder. The 77-degree cylinder angle minimizes vibration. Both are dry sump, with a separate oil tank for the gearbox and engine.
The 450 produces a claimed 60 horsepower (45 kW) at the crank, while the 550 produces a claimed 70.
