The Bike - YZF-R1

2009 YZF-R1
Benefiting from an unrivalled influence of MotoGP technology, the latest generation World Superbike Championship winning YZF-R1 represents the most significant development in engine and chassis technology ever seen in the history of the legendary motorcycle.

Featuring a revolutionary crossplane crankshaft engine and unique uneven firing order, the production model of the 2010 YZF-R1 delivers near linear torque providing smoother acceleration and greater levels of grip than previously thought possible, setting new standards for litre sportsbikes.

Minor modifications to the machine for racing from the homologated model include a modified cam-shaft, an enlarged radiator for extra cooling and the addition of an oil cooler. The YZF-R1 has no rear sub-frame but incorporates a strengthened frame. The exhaust is unique, and was developed in partnership with Akrapovic. The standard fuel tank has also been replaced with a carbon fibre tank with an increased capacity, this still falls within FIM regulations. The bike features the latest Magneti Marelli (MHT) electronic systems with over 20 sensors on the bike to monitor variables in braking, suspension and speed etc. The swing arm is also developed purely for the WSB race bike.
