Optimized Design

APTC Evo has an optimized design that requires 9 less components than a traditional clutch to be assembled.

  • Pressure plate and movable hub integrated in one piece
  • Elimination of hub-opening springs
  • Less clamping load required means less springs
  • Anticentrifugal ring

APTC Evo Components

Main Features

Assist Feature: the assist feature of the APTC Evo is on the whole plate pack, allowing a reduction up to -65% of the clutch lever effort compared to standard clutches.

Optimized helical features layout: layout: maximized surfaces, more than double than main competitor. Minimized contact pressure, less wear and indentation.

Clutch Modulation: The new lubrication path on the assist feature surfaces is leading to a perfect modulation of the clutch at bike launch, to a smoother function of the clutch while riding and during anti-hopping operation. Premium class nichel + PTFE coating minimize the friction hysteresis and stick and slip operation of the clutch.

Pre-Assembled: The APTC Evo is supplied pre-assembled for a time saving and fool-proof installation (-40sec assembling time on production line).

High energy paper based friction materials

Friction coefficient 30% more than FOR-CA-007 and more than competitor.

Positive µ-V slope: no shudder, no noise.

Strong reduction of wear rate and oil contamination compared to FOR-CA-007.

Excellent thermal resistance and friction coefficient stability in temperature.

New friction paper tiles moulding process: improved local thickness constancy for reduced jerking effect in launch.

Optimized for high power density and light weight clutches.
