The BMW S1000RR K46 stands for brutal power, precise handling, and uncompromising sportiness. However, even this performance icon benefits immensely from a targeted optimization at the right point: the rotating mass in the clutch.

The TGP MotoRacing Hyperdiscs aluminum clutch discs replace the standard steel intermediate plates and drastically reduce the weight in the clutch package. The result is a noticeably more direct engine response, a more agile riding feel, and greater control – especially when accelerating out of corners and during hard braking.

Lighter than steel – more effective than many expensive modifications

The coated aluminum intermediate plates weigh only about one third of the original steel discs. Depending on the configuration, savings of up to 700 grams of rotating mass are possible – one of the most efficient and cost-effective tuning measures for the S1000RR.

Less rotating mass means:

• faster engine revving

• more direct throttle response

• less inertia in the drivetrain

Noticeable advantages on the road and racetrack

• Faster acceleration due to reduced inertia

• Improved steering response thanks to lower gyroscopic forces

• Reduced rear wheel squat during aggressive downshifting

• Significantly better heat dissipation for consistent clutch feel under high load

Especially during sporty riding, track days, or racetrack use, the optimized clutch provides more precision, confidence, and durability.

Important for Installation

The specified measurements apply when using the original BMW friction discs (2.78 mm) in combination with the standard anti-hopping clutch. Deviating friction disc thicknesses or aftermarket clutches may alter the package dimensions.

Recommendation for Maximum Performance

For optimal results, we recommend combining the Hyperdiscs with new or nearly new friction discs. This ensures clean disengagement, consistent power transfer, and constant performance even under racing conditions.
