Two types of grooves can change a lot.
It is used with CYGNUS X Type 2 Taiwan Spec.
When I upgraded my engine to Bore up+High Camshaft+High-compressionHead, it was hard to find a NORMAL drivetrain with enough capacity, so I bought a Torque Camshaft to open it up more.
The GEAR ratio is wider than the OEM Torque Camshaft because of the larger range of motion, so the top speed is increased without sacrificing acceleration.
Also, the Torque Camshaft pin was replaced with a bare ring type to reduce friction loss and improve response.
The benefit of the largest is that you can use the Straight groove.
With the OEM engine, the response is not as good as with the Straight groove, but the Torque Camshaft opens and closes faster, so the rpm rise is better.
When combined with an engine that pulls hard with the LargeEngine Displacement Volume, the engine can reach gearshift speed in an instant, making for a very fast starting kick.
It is recommended to add a BearingSlider to the Clutch Spring for better response.
It is said that maximum speed is reduced in straight grooves, but I didn't really feel it.
As for durability, I think it's good enough since it hasn't broken even after 2 years of running with the Bore up engine.
