aprilia, the respected italian moto manufacturer, is building what could be the ultimate high performance atv motor.
displacing 450 cc, the liquid cooled, 77 degree v- twin four stroke will use single overhead cams, four titanium valves per cylinder, a redline at 14,000 rpm, electric starting, all matched to a 4 or 5 speed gearbox w\ a hydrolic clutch. called the 45.v2, it will be fuel injected to keep emmitions under controll. to keep the engines weight down the central casing will be made from aluminum-silicon, and the sidcovers are magnesium.
the dimentions of this twin cylinder engine are in fact smaller than single cylender engines on the market presently.according to aprilia. " every single engine component has been optimised not only for performance , but also for quiet running in order to meet the sound level limits currently being proposed for the sector. equal attention was also paid to limiting poluting emmisions.
