Another visible difference between 2010/11 and 2012/14 is the sharks gills face the other way..
And here's some invisible revisions ... 2010/11 vs 2012
The rear sprocket is given an extra tooth, from 44 up to 45, to aid acceleration.
Final Drive Ratio, was 1:2.588, now 1:2.647
The air-intake through the headstock has been revised to increase the surface area by 20%. The throttle action is quicker, now requiring 11% less travel. All this gives the BMW extra oomph off the corners
The new model has a shorter wheelbase, down from 1432mm to 1422.7mm.
The steering head angle changes from 24 degrees to 23.9 degrees, while trail is increased by 2.6mm.
A mid-speed damping valve has been added to the front forks and internals have been revised with the aim of improving front-end feedback.
Updated front fork with adjustable mechanical steering damper
The rear shock features a new spring and a wider range of adjustment.
The swingarm pivot is located 4mm higher in the chassis a move designed to improve suspension feel.
The bars are set wider and the reach to them is slightly greater, for more leverage than before.
The Rain power mode has been revised, from a rather meagre 152bhp to 163bhp. The main changes are to the traction control and 'combustion control'. The Dynamic Traction Control (DTC) was a popular optional extra on the original model, with over 98% of customers opting for it. BMW have revised the system, refining it, making its intervention less obvious. The 'combustion control' is used in Slick mode and is designed to help corner entry by 'opening' the throttle a minute amount to maintain the perfect amount of engine braking.
There’s less engine braking in Slick mode now. The throttle butterflies open to take some compression out of the engine when you’ve got the throttle shut entering a corner.
