BIHR and AFAM propose you this reinforced chain kit for your motocross YAMAHA YZF 250cc. This chain kit is composed of a reinforced anti-mud chain with a quick release, a sprocket and its ultra light crown. Of excellent quality, it will be mounted without worries on your enduro. The advantage of taking a complete chain kit is that you will receive this pack with a chain of the right size. No need to cut it during assembly. The original transmission for this bike is a 13 sprocket and a 51 tooth sprocket. However, you can take any size you want depending on your needs.

As a reminder, the bigger the pinion, the more speed you have. The smaller the gearbox output pinion, the more acceleration you have. For the crown wheel, it is the opposite. The bigger the crown wheel the more acceleration you have and the smaller the crown wheel the more speed you have.
