Great sprocket.
The 54T is as big as you can go on a Honda 450 RX if you want to gear it down a bit for the tight trails. Works and wears well. Ordering another.

Nothing but the finest!
There's nothing better than a black Renthal sprocket with a gold chain. Looks amazing!

Dissapointed
The colour is great looked nice on my kawi for a hour, then the minute my wheel started moving for a quick rip. The paint is gone after 5 minutes. Whole diameter, just expected the "pretty" to last more then a single ride.
You will be dissapointed with the colour after u ride, (nothings rubbing it , chain cleaner is clear and rub free)

Good sprocket
Purchased and installed this a while ago for my KLX300R. Sprocket is very light and very green. I hope it will hold up well, being that it is alluminum. Haven't had a chance to use it much since it is still the middle of winter. But I have good hopes for it.

Questions
Will this fit the forged rim on my 2016 BMW S1000RR ?
Simply enter the year, make and model of your bike on the product page to check fitment. Fitment is only confirmed on stock bikes. If your rims are aftermarket we cannot guarantee the fit.

Can you tell me if you have this sprocket for a marchesini rim? 42T, 520.
I use this for the crf250L. Hope that helps.
