Castrol Trizone technology™ represents the 21st century approach to 4T motorcycle oils. Castrol 4T oils developed with Trizone technology™ offers the protection needed to get the most out of your motorcycle.
The 4T motorcycle engine, unlike the car engine, has a very compact oil system, where the engine, clutch and gear zones are combined and use the same oil. In a car engine, the three zones are separated, with the engine and gearbox using specific oils. The ideal 4T motorcycle oil has to meet the very different requirements in all three zones of the bike: engine, clutch and gears.
A changing environmentEurope is one of the most demanding motorcycle markets in the world: European riders demand performance, quality and versatility from their machines. Operating conditions vary from near desert heat in the south to sub arctic cold in the far north, from coastal plains to high mountain passes, from stop start city traffic to wide open motorways. Noise, gaseous emissions, consumer demands and safety to name a few have all had effects on motorcycle design. Increasingly, it’s the four-stroke engine that powers big bikes, with the two-stroke confined to use in small scooters, off road and competition. Today’s high-precision, high performance four-stroke motorcycle engine provides many challenges for its engine oil.
Motorcycle engines produce a lot of power for their weight. Part of the secret lies in high engine�
speeds: a truck engine produces peak power at about two and a half thousand RPM and a car�
engine at around six thousand RPM. Modern four-stroke motorcycle engines can rev up to 15�
thousand RPM or more.
The circulating oil comes under huge thermal stress as it transfers heat away from low mass components under high power conditions. High piston speeds and power output generate very high temperatures - with few places for that heat to go. The oil plays a crucial cooling role – which demands oils with exceptional high thermal stability. But there are many other challenges that a lubricant must face:
Poor quality oil can vaporise leading to a rapid rise in oil consumption - and a fall in protection.� Compact multicylinder multivalve engines use complex oil circuitry with narrow oilways - the oil needs to be fluid enough to keep flowing under all conditions.� Deposits can build up on the pistons and rings - the oil needs to keep these clean. All the while, the oil is carrying combustion by products and wear metals into the sump and filter.Compared with truck or car engines, motorcycle engines are much smaller and lighter. Most four-stroke motorcycle engines and the lubrication systems are combined so that all these zones rely on the same oil: one oil to do three different but equally important jobs - to protect the engine, gearbox and clutch.
