Sprokets

11 posts in this topic

I have an 05 wr450 and want a new sprocket. I like the primary drive aluminum sprocket and was wondering how durable it is. The stock one was great and the primary drive steel sprockets never wear and was wondering how durable the aluminum sprockets are. I tried dropping a tooth in the front but ended up going back to stock because it spun too much for me.

Two things, I have decided to go with the renthal 51 tooth and renthal 14 tooth with a primary drive x-ring chain. Is the x-ring chain worth the extra bucks and weight? I probably wont buy it till the end of this week, (after paying for drivers test) but would like to know.

Get a supersprox stealth (tri metal) sprocket. They last and last and last.

I think the ironman ones would be great too, but the price scares me for a steel sprocket.

As for x-ring chain, it will outlast any aluminium sprocket. Pay extra. It is worth it.

I dont know if I have as much money as I once thought. After buying that DrD pipe on Ebay, and on friday I have to pay for my drivers test, I may only be able to buy a rear sprocket. I am thinking about the renthal rear 51 tooth. The tri metal is too expensive for me, but I do think its a good idea. Later after I get a job, I can probably aford a new front and maybe an x-ring chain.

If you're not trying to impress anyone and weight savings isn't an issue for you. Just get a steel sprocket. It will last longer and cost less.

I run steel sprockets front & rear with a DID 520VM Xring chain. Lasts forever!

I just wondered what all the hype was about having a lighter drivetrain, so I figured I would give it a try. I have also always ran steel but just wanted to try something new. By the way, should I stay with stock gearing or go with the 14/51 gearing?

For your gearing choice, that is up to you. If you think that the gears are too far apart and you don't use all of them, go to a bigger rear sprocket. It will make the power more snappy too. For me, this translates to heaps of wheel spin, and low top out speeds.

A steel set of sprockets and an o-ring chain can be had for very cheap. If money is tight, this is a great way to go. The steel sprockets like JT are very cheap and last for ever. An o-ring chain isn't the best, but it is close.

I tried a one tooth smaller front sprocket, but went back to stock because that extra "hit" did nothing but spin and made me more tired on my longer rides. I dont use fifth that often. I have only topped it out a few times so I was gonna try a one tooth bigger rear.

I run a 13/49 Ironman combo and I love it. 13/50 was too much but the 49 was perfect. It doesn't sound like much, but it made the right amount of difference. It's like flavors of ice cream though...everyone has their favorite...SC

You could go on and on and on about the benefits of aluminum sprockets. Rotational mass, unsprung weight, etc etc. But at what point do "you" get a return on your investment. I for one am not a factory pro rider- nor do I aspire to be one. For me the return does not outweigh the costs.

As I stated before I have a DID X-ring chain. My sprockets are SunStar and they are steel. They are also the stock gearing of 14/50. I might change gearing later after I develop some more eperience on the bike.

As for ring sizes. A change in the front is not the same as a change in the rear. See my example below. If you changed sizes on the front and thought it was too much. You might want to consider stock on the front and 1 tooth change on the rear. Just food for thought to make your decision a harder one to make. LOL
