It certainly aids my idea of fun! Having lived with a week with the bike I just love the power it can put down to the road. And if BMW came out with a black box tomorrow that delivered another 15bhp for £1000 I would buy it without hesitation.
Well, I couldnt quite find a black box delivering another 15bhp for a grand.....but I have ordered the Akra can and collector set that according to Nippy Norman's site does provide the following:
When fitted with the Akrapovic silencer the power increase is 8bhp (baffle out) and 6.5bhp with baffle in.
This figure is peak power, but does not explain the surge in mid-range power gained. There is a MASSIVE increase in torque between 3,500 and 5,500 rpm.
The increase at 5,000 is 12% more torque than standard from 88nm to 99nm
Fitting the collectors alone with the OE silencer will give about 3-4hp gain
More Power....
