2012 BMW S 1000 RR FROM-£8,600

Fast Bikes - - CORE TEST -

The big-bore, short-stroke 999cc mo­tor didn’t get any in­ter­nal treat­ment from the Mark I. It was im­proved via elec­tronic man­age­ment, plus a 20 per cent larger cross sec­tion of the air-in­take in the steer­ing head, a mod­i­fied air­box and new bell­mouth gge­om­e­try.y The dy­namic trac­tion-con­trol is based upon the 2012 HP Race Power Kit, while three rider modes fea­ture vary­ing lev­els of power and trac­tion-con­trol in­ter­ven­tion. The throt­tle valve also fea­tures a sup­port­ing spring to re­duce ac­tu­at­ing force. The 2012 bike re­ceived a mod­i­fied frame and brand new steer­ing head. The steer­ing an­gle lost 0.1 of a de­gree to make it 66º, while the wheel­base was short­ened by 9.3mm to 1,422.7mm. Trail has been length­ened by 2.6mm to 98.5mm, and the fork off­set made 2.5mm shorter to 29.5mm. Sus­pen­sion units were refined with mid-speed damp­ing and BMW also fit­ted a me­chan­i­cally ad­justed steer­ing-damper. Brakes came from Brembo, with de­cent ABS for the road, but can be switched off for track larks.
