Overview

The strongest twin system that is compatible with both circuit and street, with both ease of handling and high power.

Transmission performance/durability

  • It has a high torque of 700Nm or more, suppresses drive loss when the clutch is engaged, and exhibits excellent transmission performance. It corresponds to clutch kicking during drifting, intense clutch operation during circuit driving, and high output engine.

Measures against heat

  • Resistant to temperature changes.
  • It is resistant to temperature changes from starting at low temperatures to clutch operation at high temperatures, and exhibits a stable coefficient of friction and excellent wear performance. Therefore, the clutch feeling is stable, and the sharpness does not change with excellent control performance.

Operability

  • The pedaling force is the same as the genuine one, and the start is smooth.
  • Compared to metal discs, it enables smooth starting and clutch operation with half-clutch. In addition, the pedaling force is light and it is as easy to handle as genuine.

Quietness

  • No squealing sound is generated.
  • By adopting a strut drive system, there is no rattling sound peculiar to a multi-plate clutch when the clutch is disengaged.
