Aprilia RXV 450i (2010 - 2013)

The Aprilia RXV 450i, a revolutionary off-road motorcycle that’s been making waves since its introduction in 2006. For the 2010 model year, Aprilia has taken this already impressive machine to new heights with significant upgrades. The 77 V-twin engine is now even more potent, thanks to a new fuel system featuring stepper motor throttle body control and advanced ECU. This translates to improved performance and reduced weight.

The chassis has also undergone a transformation, with a lighter rear frame providing a lower seating position for the average-sized rider. Ergonomics have been reworked for comfort, while a new seat and swingarm make their debut. The latter boasts cast body and hydroformed members, resulting in a more flexible unit that keeps the rear wheel firmly planted.

Together with a revised brake caliper, this raft of updates yields an impressive weight reduction of 2 kg. As a result, the RXV 450i is now even more agile and responsive, making it a formidable competitor on the global Enduro market. With its unique blend of power, agility, and handling, the Aprilia RXV 450i is sure to leave its mark on the off-road scene.
