WR250R Front Sprocket Install

This is how you swap / install a front chain sprocket on a WR250R, but it is almost the same for any motorcycle. The torque specs are: front sprocket bolt - 69 lb-ft. and rear axle: 90 lb-ft. If you own one of these bikes, installing a 14 tooth front sprocket will help to keep your chain from eating the swing arm on the front. It also gives you a little more top speed, and widens 1st gear.
