Ok, so it's time to get a new sprocket and chain. The ones I have now are hammered. Ok so here'e the question. I want to run the renthal sprocket (probably the black one). What type chain do I use and do I need to do anything to the counter sprocket as far as a spacer or anything?

Also I ride both MX and off road. We do some hill climbs and the normal screw around desert stuff. What is the best gearing for such a situation? No gripes on how the bike runs now. Just want to see if I'm missing something.

For that type of riding I would strongly recomend a 48 or 49. I have a 48 and like it much better than the stock 51 but I have a 49 I am going to put on because I want just a little bit quicker pull in 3rd, 4th and 5th. Ken sells a chain that requires no spacer but it is expensive.

Gearings personal and srea you ride, but that OEM chain is very,very good, and no spacers or other crap to deal with. Doug

Problem with that chain is that it requires an expensive riveting tool. I take my chain on and off too much for the paddle tire. Matter of fact I have a brand new OEM chain (3 rides) sitting in the garage.

You don't need to take the chain off to switch tires.

The stock chain was too short, I couldn't get the paddle tire on.

Anyone seen these red chains before???

I agree with Doug I think it is personal preference. I know when I had my 250 I had a couple different sprockets for different types of riding. If you see yourself having this bike for a while, look into sidewinders. I bought them for my other bike and they were awesome. Ran them for a whole season and had hardly if any wear. A bit more money than Renthals though.

I have the iron man rear sprocket and have very little wear on it. I also put a DID X ring on with no spacing issues. It fit fine on my bike. Sidewinder and Iron man will last a couple years. The last renthal I put on only lasted a couple months before it looked like shark fins.

I had those Sidewinder Ti-Moly sprockets and chain on my last bike. I clipped a boulder inside the first 20 miles of the Henderson 300 in '04. It knocked my billet chainguide inward about 45 degrees.

I rode the remainder of the race (280 miles) with my chain rubbing at an angle on the rear sprocket. Howling the whole time. At the end, when I had time to fix it, there was hardly a wear mark on either chain nor sprocket. Couldn't believe it.

I ran that same set of chain/sprockets for another year and a half...hardly worn. They make some SERIOUS equipment. It's expensive, but worth it. Especially in the long run when you figure the costs of replacing regular aluminum stuff. It's on my list for the X.
