The rocker arm has been reduced by about 20% less than the normal rocker arm.
Reduces rocker arm moment of inertia due to reduced weight and provides smooth tracking to ultra-high speeds.
The surface is treated with special surface that is stable under high temperatures, so there is a very small coefficient of friction and reduces friction loss.
The surface hardness is also increased, so the service life is more than 10 times (depending on engine specifications).
