These sprockets do not fit a BMW X-Challenge 650 or similar G650X Rotax powered bikes.
Do not purchase these sprockets if you have a BMW X-Challenge 650 or similar Rotax powered motorcycle. They will quite literally destroy your engines output shaft splines because they only fit about 90% of the teeth. With this little amount of play and the hard metal it will cost thousands of dollars of damage to your Rotax engine. After only 3,000 mi riding this sprocket on my X-Challenge My spline shifts teeth were completely stripped... Now I need to disassemble my engine completely to replace this output shaft... There are only four of these shafts left in the world for these unicorn motorcycles and the shaft is quite expensive let alone all the time and labor to completely disassemble the motor. Do yourself a massive favor and buy the BMW factory front sprocket. The rear sprocket does not matter since it mounts directly to the cush drive in the rear wheel.I've used JT's sprockets on all my Japanese bikes in the past I never had an issue but these BMWs are a little bit different in the machining processes and these sprockets do not fit exactly to the teeth of the Rotax engine.

does not fit motorcycle as specified
bought this for my 2015 honda cb500x. It said it would fit but it doesn't. What's worse than doing a chain on your motorcycle, cutting off the chain, changing out the rear sprocket and then finding the front sprocket is wrong!! I probably won't trust amazon's vehicle compatibility rating anymore. Not worth the headache to find out it's wrong.

Top Quality Sprocket!
Purchased this sprocket for a 2014 BMW G650GS Sertao.Amazon says this this sprocket will not fit a Sertao, they are wrong.Per JT Sprockets web site, the JTF 402 is the correct sprocket for the BMW.Sprocket fit perfectly!I'm not sure what the previously reviewer was talking about.I had no slop at all in the splines.Fit just as good as the 16T factory sprocket and is a better quality steel.

Do not buy these for BMW Rotax singles!
They fit loose on shaft and cause damage to splines. Very expressive repair when it t happens.

Just even better than the original one. I use it on my BMW G650 GS 2014

Fits TR650
Fits the Husqvarna TR650 perfectly. Transformed the bike in the dirt. One tooth down from stock brought the bike to life!
