Component Features

Flywheel

Weight: only 3,85 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 floater plates.

The tightening torque for the cover-to-flywheel bolts (M8x1.25, grade 12.9) is 41 Nm.

Top/Pressure Plate

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
