Great product. I put it on my 07 wr250F and now the power on the low end comes on faster and the torque down low is great!

I bought this for my 2009 KX250F and it lasted 2 whole years before it needed to be replaced and i ride every weekend... Just bought a 2012 and it was the first thing i changed on the bike.

Product is great for the price. The teeth wear slightly faster than the reinforced sprockets but ultimately hold up very well. I will buy this sprocket again.

Fits great, looks great, and adding two extra teeth really increased the power of my crf250r and the red dresses it up nicely.

Renthal makes excellent products. This sprocket is lighter, more durable and looks better then stock. Well worth the money, I will most likely buy another.

This is a great buy!! I went up two teeth in rear which made my KX250F scream out of the berms!! I gave the Durability a 3 due to the fact the black is wearing off pretty quick from where it rubs on the chain slider.

This sprocket works great no problems so far.

The stock gearing on the 450's is way too high. I couldn't down size the counter-shaft sprocket because the O-ring chain would bore a hole in the case. Going up 2 sizes in the rear allows me to blast out of corners and lug it if I really need to. The Renthal sprocket looks better than the stock Sunstar and is much lighter too. I don't know how it wears yet and there aren't any features except the colored finish, so I really couldn't rate durability and finish.
Sprocket looks, installs, functions great!

The Renthal sprocket is much lighter than the OEM sprocket on my KLX 300. The fit, finish and function of this sprocket is very good.
