BIZOL’s range of motorcycle oils is blended from high-quality oils and additives to provide a unique level of protection. We have formulated the oil for the specific needs of motorcycle and quad engines, because we know that a motorcycle engine is different.
One of the differences is that motorcycle engines generally develop more power per litre than a car engine. The higher power output however has a downside, which is that motorcycle engines are subject to significantly higher internal temperatures and loads than car engines.
The compression ratio in a motorcycle engine is normally higher too, meaning the pressure that develops inside the cylinder and the force that acts on the crankshaft is substantially higher. Another consequence of higher compression pressure is increased combustion gas blow-by into the crankcase. Blow-by raises the concentration of contaminants in the oil, causing it to degrade faster. Motorcycle oil has to contend with a greater amount of contamination and, because a motorcycle engine usually revs at higher speeds, the oil must also be more resistant to foaming.
The majority of motorcycle engines have a common sump, which contains a lubricant for both the engine and the gearbox, The shared lubricant has to work harder than a lubricant in a car engine. Motorcycle engine oil has to provide lubrication and protection to the engine components, ensure smooth gear selection and be compatible with the gearbox and wet clutch components. Optimal clutch operation and take up of drive are additional demands that the oil must fulfil and is the reason why BIZOL Moto engine oils are formulated to maintain high levels of cleanliness.
A critical function that all engine oils have to perform is cooling. The particular challenge for motorcycle engine oil however is that motorcycle cooling systems are, in general, not as efficient as car cooling systems. In addition to lower cooling efficiency is the added stress factor that motorcycle engines have to deal with higher internal temperatures as a consequence of a higher rev range.
Checking the oil level and performing oil changes regularly is therefore vitally important to ensure the longevity of the engine and, in most cases, the gearbox.
So, as you can see, a lot thought and practical experience goes into formulating an oil suitable for a motorcycle, regardless of whether it is a supersport bike, a commuter bike or even a quad.
