Friction is so light that it is hard to believe it is a seal chain. The durability is also good. I clean and refuel the car every 800 km and it is now 25,000 km old and still going strong with no rattles. I use this Chain for all the Motorcycles I have. Other reviewers have mentioned that the clip does not fit, but a special tool is required for the light press-fit clip. This is also written in the description of the product, so please read it carefully before purchasing. There are no deficiencies in Manufacturer. If you do not have the tool, we recommend that you replace it at the shop.
It is the cheapest Chain size that fits NSR250R, but I think you have to be a very skilled person to know the difference between it and other Manufacturers. For me, the performance is good enough.
