APTC Evo
Evolution of excellence
The APTC Evo Clutch represents the evolution of our APTC, the worldwide first assist and slipper clutch on the market.
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
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.
