Great product

Fit like a charm, installed in 30 minutes, and WOW what a great addition to the KLR! Easily cruise at 70-75 on the highway at or just under 5k rpm. Took the KLR on some gnarly southwestern mountain trails with the 16 tooth and it handled just right. Plenty of low-end grunt, and got home just fine on the highway. I highly recommend the 16 tooth upgrade. Also, thanks to Motorcycle Superstore for shipping quick at a great price!

Ride the trails with control.

Smaller sprocket made the bike grip the trails with ease. You loose speed on the main roads but it worth it! Ride on!

Worked Great

I replaced my Front and Rear Sprocket along with a new Chain and everything is working great with no more noise in the sprocket chain area like it was before.

Seems pretty good

I got this for my KLR 650. It fit good and the finish seems like good quality. I have only used it for 400ish miles but seems great so far. I don't suspect I will have any issues with it and, as of now, would buy again.

great product bad fitment chart

I like the product company they’re great, but going by the fitment chart from the site the sprocket didn’t fit.

sprocket

Good service & delivery. Thought I'd try one tooth higher than stock 16 on my gs500f. Lowered rpm about 500 at the same previous speed and shifting intervals seem smoother. I'd recommend it depending on your riding style.
