Types of Lubricant

Lubricant in motorcycle engine is very important. The lumbricant has functions of reducing the effect of friction and keeping the engine temperature. The lubricant must be able to penetrate into very narrow gap and must be fast lubricating. Without lubricant, engine will stop because of overheating and engine parts will be broken too.

Now, lubricant types are various. The most common type of lubricant used  many people are 20W-50. This lubricant has thick viscosity. Lubricant of 20W-50 does not easily penetrate and make the engine moving slowly. Therefore, sport motorcycle needs thinner viscosity, 10W-30. Lubricant of 10W-30 can easily penetrate and engine can move faster. This lubricant is ussually used in high rotation engine such as motor racing and motor matic. This type of lubricant is ussually easy evaporated. When the engine is hot, the lubricant will evaporated cause of thin viscosity. So, people use in between type of lubricant, 15W-40 or 10W-40. If you tend to like thick viscosity lubricant but want to  get faster lubricating, you can use 20W-40 lubricant.

So, what motor you have and what character you are, it determines the lubricant. Have a nice and safe riding.

What motorcycle do you have? Every motorcycle uses bearing at its wheel. Some motorcycles have the same size of bearing. Yamaha, Honda, & Suzuki have the same size of bearing at rear wheel. Suzuki and Honda also have the same size of bearing at front wheel.

Usually, the sizes of bearing that are commonly used are 6301, 6201, 6300, 6203, etc. Bearing of Honda and Suzuki is made by SKF. Bearing of Yamaha is made by Toyo or NTN. They issue two types: without cap and with cap. Bearing with cap is better because the grease will not be easily thrown out (cause of rotation) and the water cannot easily get into the bearing. If we are price concern, Suzuki's bearing price is cheapest. If you use size of 6301, Suzuki' price is around Rp 19,000, Honda's is around Rp 22,000 and Yamaha's price is around Rp 30,000. Suzuki's bearing price of 6300 is around Rp 17,000 and Yamaha's is around Rp 20,000. Suzuki's bearing price of 6201 is 13,000, Honda's is Rp 15,000 and Yamaha's is Rp 16,000.

I think they have the same quality but their prices are different. So, which one do you choose? Have a nice & safe riding!
