BMW Homologates New S1000RR Crankshaft

07/07/2010 @ 5:56 pm, by Jensen Beeler7 COMMENTS

The FIM has announced that BMW has homologated a new crankshaft design for World Superbike and World Superstock racing. Effective since June 10th, the new crankshaft, much like the Aprilia RSV4’s upgraded camshaft, could be part of the equation for BMW’s recent success in WSBK, and continued domination in STK1000.

BMW has a commanding lead on the manufacturer’s points in STK1000, with rider Ayrton Badovini having nearly double the points of his nearest competitor (125 points to the 66 points of Maxime Berger). Meanwhile in WSBK, Troy Corser has shown improved form over the past two race weekends, and the BMW team has its sights set on a race win at Brno, which has been a strong track for the Bavarian team.

With the new crankshaft seemingly making an improvement on Corser’s results, the Australian will be looking to improve upon his 5th and 10th place finishes. Meanwhile Ruben Xaus just hopes to keep his S1000RR out of the gravel traps, and off the mechanic’s bench.

    Cool! Big-bang?

  • We’re still looking for what was actually changed to the crank, more as we get it.

    I imagine it would be about inertia, rather than a radical change of firing order.

    I think MF is right unless other parts are changed too. Inertia, durability or something like that. Now if there are different cams in there as well they could be playing with the firing order:)
