TGP MotoRacing Hyperdiscs Aluminium Clutch Plates – BMW S1000RR K46 (2009–2018)

If you are looking for one of the most cost-effective performance upgrades available for the BMW S1000RR K46, the TGP MotoRacing Hyperdiscs deliver a measurable, real-world improvement that pays dividends every time you ride — on the daily commute, at a trackday, or flat out on circuit. By replacing the standard steel friction plates with coated aluminium equivalents that weigh roughly one third as much, you shed up to 700 g of rotating mass from the clutch pack and immediately feel the difference in throttle response, corner entry and drivetrain fluidity.

Key Features

• Coated aluminium clutch plates weigh approximately one third of the original steel items, cutting up to 700 g of rotating mass from the clutch pack
• Faster engine rev response and more immediate throttle pick-up thanks to dramatically reduced rotational inertia
• Improved corner-entry behaviour as lower gyroscopic forces allow the bike to turn-in more freely
• Reduced rear-wheel hop and stamp under aggressive downshifting
• Superior heat dissipation for consistent clutch feel even under sustained high-load use
• Designed to work with the factory OE anti-hopping clutch (OE AHK) — no additional modifications required

Everyday Usability and Real-World Value

Unlike exotic engine internals or bespoke suspension components, the Hyperdiscs are a straightforward drop-in upgrade that slots into the existing clutch basket alongside the standard friction plates. There is no need to alter the clutch actuation system, replace the basket, or recalibrate electronics. The result is a perceptibly crisper drivetrain character that improves both the relaxed pace of a weekend road ride and the precision demanded by back-to-back laps on a circuit. For riders who want genuine performance gains without a five-figure parts bill, this is one of the most efficient investments available for the S1000RR K46.

Performance on Road and Track

Reduced rotational inertia translates directly into faster acceleration out of corners, where the engine no longer has to overcome the angular momentum of heavier steel plates before delivering drive to the rear wheel. At the other end of the straight, the lower gyroscopic effect in the clutch pack contributes to cleaner, more predictable corner entry. Riders who use the slipper function hard will also notice that the anti-hopping mechanism works with greater consistency, because there is simply less mass fighting against the mechanism during aggressive downshifts. The aluminium's superior thermal conductivity keeps clutch feel stable during prolonged high-temperature running — important on track where repeated slow chicanes or long queues into a heavy braking zone can heat a steel clutch pack significantly.

Fitment and Compatibility

These Hyperdiscs are engineered specifically for the BMW S1000RR in the K46 frame generation. The dimensions and tooth count are matched to the original BMW clutch basket used across the full production run of this model.

• Fitment: BMW S1000RR K46
• Model years: 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018
• Compatible clutch type: original OE anti-hopping clutch (OE AHK)

The stated dimensions apply when the Hyperdiscs are used with the original BMW friction plates at 2.78 mm thickness. If you use aftermarket friction plates of a different thickness, or a third-party clutch assembly, the total stack height will differ and must be verified before installation. For best results, TGP MotoRacing recommend pairing the Hyperdiscs with new or as-new friction plates to ensure clean clutch release, even engagement and consistent performance under racing conditions.
