Aprilia MXV450 Enters Motocross Arena
Utilizes variable ignition V-Twin
Aprilia has recently jumped into the motocross category with both feet by launching the new 2009 MXV450. A first for the company and the only V-Twin-equipped motocross bike in the world, the MXV 450 promises to combine a high-performance engine with authentic Italian style, light weight and advanced technology.
Equipped with Aprilia’s 452cc electronic-fuel injected 77-degree V-Twin engine, the 450 MXV allows riders to choose between two ignition settings – a factory default setting that favors rideability, control and traction, thanks to the closed firing gap between the two cylinders, and the “Screamer” setting that modifies the firing gap, allowing for maximum engine performance up to the 12,500 rpm limit.
The Dell’Orto fuel injection system is managed by a programmable electronic control unit (ECU) that allows riders to switch between hard/soft mappings at the touch of a button on the handlebars. Elimination of the external oil tank and its connecting pipes led to a reduction in weight, as did the elimination of a starter motor in favor of a good ol’ fashioned kick starter.
Available in U.S. dealerships now, the 2009 Aprilia MXV450 has an MSRP of $8,499.
