The motor blur system is a system to detect the state of the engine (motor) and optimize the pressure state inside the crankcase.
It keeps crankcase internal pressure in proper condition just by installing, and relieves excessive engine brake.
It eliminates the rear wheel lock during entering the corner and the unexpected acceleration (don thrust) of the rise and realizes smooth running.
In particular, the engine that shares one crankcase like DUCATI 's L - shaped twin can be more effective because the compression resistance inside the case is large due to its structure.
There is a case that the resistance decreases by wearing and the idle rotation increases 200 to 500 rpm.
It is quickly change to a smooth and torqueful feeling over the whole area by mounting it.
Please feel at all means car that changes such as tuning the engine.
