Good. Its use was done on a perfectly clean chain which was cleaned with paraffin oil, toothbrush, and brush and dried with an air compressor (see also my review for C2). It lasts a little longer than the transparent C2, unless it's just my idea because its white color stays for a while and its content of Teflon deceives you. When you touch the chain after a while, you don't feel like you're touching real oil. It splatters less than C2 and splatters white spots, so it is very noticeable on dark or black rims. It cleans easily like C2. The splattering will last for about 100 kilometers at most, and it will be at its peak on the first ride. Its white color makes the chain look very bad. So if you don't care about the appearance of your chain, try it. I switched back to C2 and will keep C4 for my work scooter.

Quite good, I consider it a good choice even if one does not use the motorcycle intensively. The company also recommends that when using the product, you let it absorb into the chain for one to two hours. Do not spray and immediately use the engine because it throws it away and it's like not using it at all. It dries normally, it takes time. Also, we spray it on the inside of the chain and not towards the outside.

The best I have tried from chain lubricants.... It stays on the chain and doesn't throw it onto the engine and it cleans easily.

It contains Teflon, which makes dust stick more easily than other lubricants on the chain... so if you pass through dirt or there is a lot of dust in your area, it's better to go for c2 or c3, otherwise you will have to clean it more often than usual.

Very good! It is like the iPhone but more condensed and tight when it dries. It does not break at high speeds and temperatures. The chain is completely silent.
