Vortex CK6317 Racing Sprocket Kit , Black

Worked great on my 2004 Yamaha r6 but if you got your bike extended you will need a longer chain!

Great product. I've had it for a month now and its holding up great. Its fit perfect and easy to install. I'd buy it again next time around.

BAM.. love it. Fair price... LOVE the torque upgrade. It's not TOO much.. I mean.. if you want to stunt than consider buying a huge stunt sprocket. This is a good beginners experience to feeling more low end power. Otherwise this thing is a great addition to the ride! You instantly feel the "torqueeness" and its not too much.. but that front wheel WILL come off the ground if you twist that throttle hard. Love that feeling (by the way, invest in a steering damper). Gonna enjoy riding this for quite a while. I have 2 R6's and this is on one of them. 1 for speed and 1 for fun. Been riding for a long time and wondering why I never did the 520 conversion sooner.

This kit works great on my 2016 R6. The acceleration greatly improved and if you like wheelies they come up with ease. All the parts fit great and the chain comes with the correct length so you don’t have to mess with removing links

What in the world! I don't know I did know upgrade sooner, this kit definitely exceeded my expectations. I was told that my top speed was going to suffer greatly with this configuration but I have proven the naysayers wrong. I used an app called DigiHUD Pro because it allowed me to offset the speed for better calibration because I didn't want to buy a standalone GPS since the one in my phone is pretty accurate. Now the torque is unexpected and pulls pretty hard when you open throttle like you mean it. I had to order a set of tank pads because I keep sliding back and losing position whenever I take off.

I installed this on my 2004 Yamaha R6, and let me just say one thing; 1st gear and 2nd gear can be fun as hell if you know what you're doing. That wheel will 100% come up without doing a clutch up, just yank that throttle a little. It's not full on stunt gearing, but it sure is fun as hell. Fit like a dime piece during install too. Really good material.

I recommend buying this brand best upgrade I've done to my bike thus far, the quality is excellent and will be buying it again when is time to replace the one I got on now

Me guíe por la recomendación de amazon, la cual manifestaba que era compatible con mi moto KTM 390 adventure y me lleve una sorpresa muy grande al ver que no son compatibles. Solicito el reembolso del dinero o el producto que corresponda. No sé cómo pedir el reembolso alguien que me pueda ayudar
