Kawasaki rear sprocket on a Yamaha: will I destroy my hub?

Don't do it.

Sounds like a good way to trash a hub, but that’s just a guess. What you are describing is like cars and trucks and whether the wheels are hub centric or lug centric. Hub centric is much stronger and will center better as it’s not relying on the bolts to center the wheel (or in this case sprocket).

Make sure its properly torqued no matter what you do....

actually, unless you are an intermediate or pro level rider, it will not damage anything, but hopefully it is attached with tapered head bolts, however, the bolts might tend to loosen up so the should be checked fairly frequently. this being said, if it were me. i would just buy the correct sprocket. i would thing you could get one for around $40.00 but i don't know for certain.

Why chance it.

Over $50.00?

go ahead and run it, and let us know how it turns out.

There it is.

No way

Nope. Don’t risk it

Primary drive makes cheap sprockets. Just get one. Theyre not that bad.

Peely to the courtesy phone.

Go up 2 teeth.

Go up 3 teeth......that thing will bark out of the turns

19.99 for the proper sprocket for your bike.
7.00 for shipping.

Ending up in er because the sprocket sheared off at the wrong time pitching you over the bars, mangling the hub, and the rest of the bike in the wreck to save a few bucks. Priceless. Always travel with mastercard.

Your trashed hub will be the least of your concern when your chain derails and puts a hole in your case.

Yes you can.

Be sure to let your riding buddies know what hospital you want to go to when it malfunctions over a jump.

I say no for Peace Of Mind.

I’ve actually done this before, Kawasaki kxf sprocket onto a wr/yz hub. I dont recall noticing any difference in the center ring dimension, I thought they were same. I ran it for maybe 10 hours with no problems.

Had I saw the difference, I would have been weary. Are the renthal sprockets you have 50 or 51 tooth? I may be interested in them if you want to just get a Yamaha speocket.

This... because only intermediate and pro riders know how the twist the throttle wide open, novice and beginners do not know how to do that at their stage of training.

The bore keeps the sprocket running true, the bolts keep it from rotating ( on the hub )

The bolts are nowhere accurate enough to make it run true. Studs on a car are pressed into a flange and the lugnuts and wheels have matching tapers. Sprocket bolts slip through a hole larger than the bolt and tighten with a nut. One side might locate accurately ( being a flat head bolt ) but the other is not even close to the accuracy you need.

As long as you don`t run Super tech oil, it will be just fine. That oil will wreck your chain, blow up your engine and make your wife run off with the pool boy......

wow, thanks for the input.

I suppose I will get the correct sprocket.

Not the five pound steel primary drive sprocket lol... I honestly dont think this is a safety issue- more of an ovaled out and trashed mounting hole issue. That is what seems to be at least somewhat likely if I run these sprockets long term, and I dont want to trash my hub...
