The motor is the biggest single area of improvement over the previous model. Engineering development was handed over to the spanner magicians at Ricardo – the same firm that designed the gearbox for the 1000bhp Bugatti Veyron hypercar. This is the first time BMW has worked with Ricardo on one of its bikes. The result is a claimed 173bhp from an increased 1293cc four-cylinder motor that is much smoother with bundles of power and torque. It’s one of the best big-capacity motors on the road today combining lovely refinement with a racing engine snarl when pushed. And yes, it’s very, very, very fast. The only question is how long you can hang on.
