Variable valves open up new frontiers in internal pressure control.
The "Superb" valve, which actively controls the pressure reduction effect according to the throttle work, is a product that is different from the conventional valve that only reduces the crankcase internal pressure.

Optimum decompression effect in ever-changing road conditions and situations...
In order to achieve this goal, we have developed a completely new internal pressure control valve using a variable stroke valve.

When the throttle is opened and the internal pressure of the crankcase increases rapidly, the valve, which is regulated by the spring set in the internal pressure controller, opens and the stroke increases to produce a larger pressure reduction effect. braking.
As a result, it is possible to show the unparalleled acceleration by the high decompression effect at the time of acceleration, and to obtain the characteristic that is easy to handle by moderate engine braking at the time of deceleration.

The Superb, which adjusts the pressure reduction effect according to the crankcase internal pressure, opens up a new stage in crankcase internal pressure control, despite its simple structure that does not use electronic devices or power.
