I got a little over 14,000 miles on the sprocket before it needed to get replaced (and mainly because of my chain stretching). riding was split between 20% hard riding and 80% cruising/street. Looks nice, but due to it's gold color, road grime and most chain lubes will make it look dirty.

This sprocket works great, I'm using 520 convertion kit with RK chain for my 2006 R1. 1 down and 2 up in rear. This kits last over hard riding 15,000 miles. Yes it's the best bang for the bucks.
This is the lightest rear sprocket ever! ( yes 0.7lbs) You will feel then weight reduction upon accelerating. Motosport hands down has the BESTpricing available. My sprocket came in a different color than pictured, a super-sexy anoidized gold which I like better than the black. If you are buying for performance like I am, look no further. If you want to buy for looks, than buy one of those "chromed out poorly engineered, heavy gears to match your polished out frame and extendended swingarms that accelerates like a hybrid mini van". I have done alot of research on rear sprockets and Renthal is the only company who cuts out there gears out of an aluminum block rather than stamped gears which puts hairline cracks in the sprockets. You might spend a little more $ for a Renthal, but you are buying a superior product, you do get what you pay for. And Motosport has super fast and reliable shipping.
Great PRICE hard to beet Color and all parts Mach what is in the picture I like that there is free fast shipping and not sometihg that takes 2 weeks....I also ordered front sprocket and a RK chain...GREAT SERVICE AND EASY NO HASSLE CHECKOUT
sprocket is color as pictured, very lightweight lighter then vortex and cheaper if you dont want a colored sprocket
Install was perfect! Fit right up just as it should, however, the color in the picture shown as a dark grey was not what arrived. Instead, it's a light seafoam greenish yellow color. The color is the only thing I was not pleased with. It looks great with the RK Gold chain, but by itself it leaves little to be desired.
