I love Sunstar sprockets. They have been my sprocket of choice for over 10 years. They wear well and are priced right. I know that the "R" product is probably more popular. I have used both and just like Sunstar better.

Long lasting sprockets!
I race desert & go to the sand dunes & with the proper chain tenstion & lube & chain cleaning after every riding trip you could get hundreds of miles out of the sprocket. I have this sprocket in a 47 tooth on my 2006 YZ450 with a DID o-ring chain & iv gotten a full year and a few hundred miles out of this sprocket.

We needed more low end/mid range power from my son's CR 85RB (expert or big wheel), which had the stock chain and sprockets. The stock setup which is excellent for top end screaming was difficult to use for what we ride, which is tight and technical trails. Since no 'complete kit' on the market was offering the range that we were looking for we bought each piece ala carte.

He loves his new setup. The powerband has shifted to the front and now when he pulls on the throttle he goes. Hill climbs have become much easier and he can even tractor up them with the new found usable power...
His new set up is a 14/56 which is (-1/+1) from stock. The ratio is 4% now which is a change of +9.28% from stock...
