At first, I was concerned if the gear would fit my Motorcycle. I had trouble determining if the gear would fit my 2024 Kawasaki 450 Eliminator. But knowing how outstanding the return system works at Amazon I rolled the dice and ordered the 15-tooth gear. It arrived in only 2 days and fit perfectly. Changed it in about 1/2 hour and was very pleased with the quality, ease of installation, and performance of the bike with the new gear.

I used this on my 2017 Kawasaki Versys 300X and it works great. I still have plenty of granny in the low gear but it will run up to about 92 mph on the interstate but the mileage increase is fantastic. No regrets and all the computer stuff still works like distance to empty and mpg estimates.

Part works great, good quality. Actually removed a 13 tooth jt sprocket from the previous owner and that had no noticeable wear at all and I’ve got 3000 miles on the 13 tooth. I think it’s safe to say the company supplies quality parts. My gripe is other reviews given. Mentioning low on power in 6th and all this other negative feedback. It is not the sprockets fault you are low on power in any gear. It’s how ratios work. I started with a 13/45 setup and had crazy low end power nothing up top. Now I’m back to stick with a 3:1 15/45 sprocket set. It’s all in what you’re after. I got sick of shifting so much and popping wheelies. So I stiffened up the rear shock got rid of that 13t sprocket. Now I have all my gears back. That doesn’t mean the 13t was a bad sprocket it means I just ain’t trying to ride wheelies and get blown all over the road at 80 mph cause I spent all my power 1 thru 4

Bought the sprocket for my 2017 Versys-X 300. Delivery was super fast and fitment was easy:Ride for 15 mins to warm up the engine. Remove plastic sprocket cover. Flatten safety washer to access the retaining nut. Loosen the retaining nut. Loosen the rear axle nut and adjusters. Move the wheel forward to put slack in the chain. Remove the chain from the rear sprocket then pull the front sprocket off with the chain still attached. Put the old sprocket aside and fit the new one with some oil/grease as instructed. Replace the washer and nut and tighten lightly until they are seated properly. Replace the chain onto the rear sprocket. Adjust the rear wheel until the chain slack is within spec as indicated on the swingarm. Tighten the rear wheel to spec using a torque wrench. Lock the rear brake and tighten the sprocket nut to spec using the torque wrench.Replace the plastic cover.1 tooth more is approx a 7 % decrease in RPM and doesn't affect any of the bike electronic functions.

Install went smoothly on my 2019 versys x 300. Fits perfect. It does make more noise than the factory sprocket but for the price I'm not complaining. I generally only hear it when coming to a stop. Much better gearing for any situation. First gear is actually usable now as is 5th. Reduced my rpms by approximately 500. Bike feels much better at all speeds while still having plenty of power.

Good product, not a big difference noticed but a slight bit better rpm reduction, Good price, no instructions to tell you which way to face the rim or spaced edge. Faced the rim/logo out like you would suspect, seems to be ok, at least for now, have been told i'm right and wrong, who knows?

This product fit perfectly. Took me 30 minutes to install. Go to gear commander .com to see just what exactly the difference is.But to sum it up, it makes all the speed of the gears increase, so You can move faster at lower Rpm's, making our short first gear much more usable. And I can easily go 70+ Mph and still ride in Eco mode. Amazing.Now I actually have an overdrive gear. It will feel like a whole new bike. For $15.00 if you don't like it, switch it back. So easy to install, I had a Ingersoll Rand impact, something you will need to get the 27mm if I remember correctly Bolt for the sprocket off. So easy to install. I rode this up in Pa 125 route, lots of twisties, the gearing and rpm-torque is great for that with this setup, I can stretch the gears out longer in 4th gear, I like it. It's the cheapest most noticable Difference you can get per Dollar.

The product came well packaged. It looks of great quality and the fitment was perfect. I noticed NO difference in low or top end torque or speed, as compared to the stock 14T. First gear is actually usable now!The shipping was fast.I recommend this product to anyone who wants a little longer first gear.
