 Component Features

Flywheel

• Weight: only 2.96 kg
• Material: Forged CrMo steel, nitriding heat-treated
• Hardness: HRC 58–62 → over twice as hard as standard flywheels
  → Prevents wear on starter ring gear in high-compression engines
• Longevity: High surface hardness = extended service life & reliability

Clutch Cover

• Material: Forged 6061-T6 aluminum, hard anodized
• Construction: Steel-riveted legs for near-lifetime durability. Hardened steel thrust buttons/rivets offer a smooth and durable surface for the clutch cover legs, pressure, and floating plates.
• The tightening torque for the cover-to-flywheel bolts (M8x1.25, grade 12.9) is 41 Nm.

Top/Pressure & Floating Plates

• Material: Forged chromoly steel, cryogenically treated (in some applications)

Sintered Clutch Discs — Ø184 mm (7.25")

• Material: Proprietary blend of sintered metal compounds, engineered with precise manufacturing tolerances
• Standard version design: Three large friction pads for optimal engagement and reliability.
• Spline: 10T x 29 mm & 10T x 35 mm (other spline options available upon request)
• Hub: Machined from forged chromoly steel and induction hardened for maximum strength and wear resistance
• Customization: Available on request (e.g. custom spline)

Clutch release bearing + specific aluminum support

• Bearing: racing-grade quality release bearing, essential for any race clutch to withstands extreme mechanical loads and high working temperatures
• Aluminum support: AL6061-T6 with hard anodize finish for a lightweight yet strong component. Available in two sizes, one specific for 10T x 29 mm mainshafts and a second version for the 10T x 35 mm mainshafts.

Flywheel to crankshaft bolts :
