- Humachine Technologies & Sensual Racing Form -
The YZF-R1 and YZF-R6 are equipped with under cowls that are based on the image of a diffuser, to give them the best form for aero-management. These are not cowls for simply enclosing the engine, but forms composed of blade surfaces that actively control airflow. This spirit has been directly inherited by the YZF-R15.

In this type of engine coolant fluid is used to cool the enigne than the conventional air cooling engine system which uses the running air flow to cool the engine.The coolant in liquid cooled engine absorbs the engine noise. Liquid cooling ensures stable engine performance in high speed riding, on up hills, in traffic jams and on hot days.The similar technology is used in MOTO GP.
