I chose it because it is affordable with the same manufacturer as the original parts of the bike. Especially after the exchange there are no problems and I am satisfied.
We used it for front wheel bearing exchange of CBR 250 RR. I was looking for one side shield type of rubber type. It is easier than ordering at a bike shop in the neighborhood and it is free shipping on over 3000 yen, so I think that it is good when there are other items you want.
