Aluminum rear sprocket on a DRZ400s???

Recommended Posts

I didn't realize the factory rear sprocket on my 01 DRZ400s was steel when I ordered an aluminum 47 tooth sprocket.

Will the aluminum hold up to street riding use?

Thanks

doubt it, probably wear out real quick.

sprockets are cheap anyways, so it's not like you wasted much money if you don't want the sprocket.

how about running it a while and giving us a report? I would guess on the street and with the o-ring chain it will last a year anyway?

I put a 48 tooth aluminium on my S last year. Have about 1300 miles on the sprocket (1/2 street)

and shows very little wear. Saves about 1 LB also!

I ran an aluminum sprocket to replace the stock one and it was toast in 300 miles. I don't remember the brand, Sun***???. It was terrible. I put on another better quality sprocket and it lasted 1000 miles or so. Two weeks ago, I went back to steel sprockets. They last a very long time and unless you are one of the factory GNCC boys, you'll never notice the extra pound. Remember, when you replace one piece, replace them all. Any wear patterns on any of the old parts will transfer to the newer ones, thus limiting the life of the part.

hey,

I have an '01 "s" and changed to a sprocket specialist 44 aluminum rear at 150 miles on the bike. I have about 700 now and ride mostly on-road. So far, I've had good luck with the SS and hope it holds up. Do a search for "sprocket nightmare" to find out what I went through to get the front 14t Ss steel to work right... Later,

I have to go knock on some wood!

Thanks guys. You are starting to make me feel better. Now that winter is upon us, I won't be riding it till Spring, but I'll give you a report on how it holds us.

my 49T sprocket specialist aluminum rear sprocket went on @ 50 miles, and now has 3500mi on it and i think the stock chain is needing replacement, so i will replace both sprockets too, but i haven't had a problem. btw, 2500 of those 3500 miles are road miles, which is a lot harder on it.

I put 35,000+ miles on an aluminum rear sprocket on my KLR650 mostly street riding. I have an aluminum r. sprocket on my Ducati E-900 with 25,000 and it looks like new. Chains last longer on aluminum sprockets because aluminum is more obsorbent therefore transmits less shock to the chain. I got over 300,000 miles on motorcycles behind me and have gone throu more than 50 motorcycles.

The key is to replace your chain before it is worn out. I just replace the chain on my DRZ at 2,000 miles (mostly mud)and the sprocket is like new. The chain could have gone another 500 or more miles but it was getting stiff making the bike hard to roll around even when well lubed.

You guys are making me feel even better. I was almost sick when I took off the factory sprocket and found out it was steel when I ordered an aluminum.

I'll let you all know how I come out once I start riding again this Spring.

Thanks again.
