Kawasaki Versys X 300 - 15 Tooth Sprocket Installation

In this video I install a 15 tooth sprocket on the Kawasaki Versys X 300. The sprocket spaces the shifting points out a bit more than the stock 14 tooth. It also let's the bike rev a little lower at any given speed. Sorry about the typos in the captioning... I was in a hurry getting this finished.

One note that is not that obvious in the video - Before torquing down the sprocket nut, I tightened the rear axle temporarily. Then loosened it after to do the alignment and chain slack.

It is important to also note that you can only change the sprocket ratio a small amount on the Versys-X or you will get an engine code and/or your gear indicator will fault out. I believe you can go up or down one tooth on the front, or up or down 2-3 teeth on the rear sprocket (but not both) to stay within the limits of what the bike ECU is expecting. My 15 tooth sprocket has now been on several hundred miles and is a great upgrade, and I have had no issues with it or the bike since installing it.

The sprocket I used is JT Sprockets JTF1539.15 and I purchased on Amazon here:

I recommend an impact wrench for this job, but it is not completely necessary. The one I have was from Harbor Freight and was less than $40 with a 20% off coupon they send me just about weekly. It is not the best impact wrench by far, but I only need one very few times a year, and it has worked fine for over 2 years of occasional use. Many big hardware and even auto retail chains even rent or loan tools... or maybe you know someone with an impact.
