The 2011 Aprilia Dorsoduro looks like a BMX bike with fat, nearly-smooth highway tires. On the black and white model, the gold forks are a true standout design though. The 2011 Aprilia Dorsoduro looks like it would be as at home on a dirt course as it would on the road. That is intentional. It is a supermoto, a cross-bike. It may not be race-ready, but race-ready is where its inspiration derives. It could be prepared for track duty without excessive mods. Very similar to the Dorsoduro 750, the 2011 Aprilia Dorsoduro has a brand-new, 1200cc, V-twin engine, angled at 90 degrees, that is cooled by liquid. With four valves per cylinder and a double overhead camshaft, the design does not break new ground. Horsepower output of 130, though, will cover lots of new ground as it speeds down the highway, or the track, as the case may be. Micro-nebuliser injectors do their part to get the ravenous engine the fuel it needs. The result of that injection setup is ideal combustion: clean power. Contributing to the clean power is a twin-spark ignition system, burning fuel all the more effectively. The 2011 Dorsoduro 1200 has a ride-by-wire throttle with three power modes: Sport, Tour and Rain. Aprilia was the first cycle builder to introduce ride-by-wire, and they lead the pack in the design and application of the technology. Traction control and anti-lock brakes add modern tech safety touches. Here is how the power modes are applied: Sport mode is for extreme performance, power unrestrained. Touring mode produces smooth performance, applying the plentiful power appropriately in all road conditions. Rain mode balances things out, reducing output to 100 horsepower in poor grip or wet conditions.
