A new, more simplified internal design for the electronic control unit (ECU) results in a modest reduction in its weight, making yet another small but significant contribution to the overall weight loss. A new magnesium ACG cover further contributes to reduced engine and overall machine weight; previously, only the head cover and oil pan had been constructed of magnesium. | A new, more simplified internal design for the electronic control unit (ECU) results in a modest reduction in its weight, making yet another small but significant contribution to the overall weight loss.

Other detail improvements abound. A revised internal crankcase venting system reduces power loss due to crankcase pressurization. A lighter cam chain tensioner slices weight from the engine, as does a new cooling system [[impeller]], which also improves flow for enhanced engine cooling and reduced heat-induced power loss. A larger-diameter thrust washer in the clutch provides more surface area and a wider needle bearing in the clutch basket adds strength and durability. The result is greater durability and smoother clutch engagement action as well. The shift drum shaft has been changed to reduce weight, and the transmission engagement dogs are undercut more for more positive shifting and less driveline lash. | Other detail improvements abound.

On the intake side, the internal shape of the ram-air intake ducts have been altered to improve airflow and the grill covering the intake system now features a larger grid pattern for enhanced flow. The upper "showerhead" fuel injectors in the DSFI system now feature a revised spray pattern for greater efficiency as well. | On the intake side, the internal shape of the ram-air intake ducts have been altered to improve airflow and the grill covering the intake system now features a larger grid pattern for enhanced flow.
