TGP MotoRacing Aluminium Clutch Hyperdiscs for Yamaha YZF-R1/M RN32, RN49, RN65 (2015–2026)

The Yamaha YZF-R1 and R1M are built around uncompromising Crossplane CP4 technology, and the clutch is at the heart of how that power translates into control — especially under the aggressive engine braking this motor delivers. TGP MotoRacing's Hyperdisc aluminium clutch plates replace the standard steel intermediate discs with coated aluminium counterparts, reducing rotating mass in the clutch pack and transforming how the R1 responds throughout its rev range, at every corner entry and exit.

Key Features

• Coated aluminium intermediate discs replace stock steel plates, meaningfully cutting rotating mass in the clutch pack
• Faster engine response on the way up through the rev range and crisper throttle pick-up at corner exits
• Calmer rear-end behaviour under hard braking, with noticeably reduced rear-wheel chatter on aggressive downshifts
• Improved heat dissipation for a consistent clutch feel across long track sessions
• Available in two variant-specific configurations — one for the standard Yamaha OE clutch, one for STM and Suter slipper clutch systems — ensuring correct pack thickness and clean clutch action
• Precise fitment across all R1 and R1M derivatives on chassis codes RN32, RN49 and RN65, model years 2015 to 2026

Engineered for the CP4's Character

The R1's inline-four Crossplane engine produces a distinctive torque pulse that rewards precise clutch management, particularly when braking deep into corners and snapping down through the gearbox. Reducing the inertia within the clutch pack directly addresses one of the few remaining variables — drivetrain lag — letting the chassis settle faster and giving the rider a cleaner, more predictable feedback loop from corner entry through to the apex and beyond. The Hyperdiscs achieve this not through a radical redesign but through material science: aluminium in place of steel, carefully coated and dimensioned to slot directly into the existing clutch housing.

Two Variants, Precisely Matched to Your Clutch System

TGP MotoRacing have developed the Hyperdiscs in model-specific and clutch-specific configurations. It is essential to identify which clutch system is fitted to your R1 before ordering, as the pack dimensions and tooth counts differ between the standard Yamaha OE unit and aftermarket STM or Suter slipper clutches. Selecting the wrong variant will affect separation behaviour, durability and overall function.

Variant 1 — Original Yamaha OE Clutch

Variant 2 — STM or Suter Slipper Clutch

• Scope of delivery: 8 aluminium intermediate discs
• Configuration: 7 × 2.3 mm + 2 × 2.5 mm
• Clutch pack thickness: 21.1 mm
• Tooth count: 34 teeth
• Outer diameter: Ø 132.75 mm
• Fits: STM and Suter clutch systems

Important Note Before Ordering

Please confirm which clutch system is installed on your motorcycle — standard Yamaha OE or STM/Suter — before selecting a variant. The correct choice is critical to proper clutch engagement, clean separation behaviour and long-term durability. If in doubt, contact us before purchasing.

Fitment and Compatibility

These Hyperdiscs are designed exclusively for the Yamaha YZF-R1 and YZF-R1M across chassis codes RN32, RN49 and RN65, covering model years 2015 through to 2026. They are available in variants matched to either the standard Yamaha OE clutch basket or to STM and Suter aftermarket slipper clutch systems.

Performance Recommendation

For optimal clutch engagement, clean separation and consistent long-term performance, TGP MotoRacing recommend fitting the Hyperdiscs alongside new or as-new friction plates. The combination delivers a precise, fade-resistant clutch pack that is equally at home on a trackday machine or a full race build.
