Overview
During traveling, the inside of the crankcase is pressurized by the high-speed reciprocating motion of the piston. This pressure builds and becomes a large resistance to the piston's movement, causing various harmful effects.
The AELLA Crankcase Breather /
internal pressure control valve keeps the crankcase's internal pressure
optimized. This optimization has many positive effects on your
motorcycle, such as: A reduction of vibration of the engine, A reduction
of engine braking which is criticized as being too strong on the L-twin
engines, and the entry of the corner becomes easier, with greater
control.
You can also experience the improvement of torque as it is smoothed and improved, as if you had a custom build/tune of the engine.
