KTM Cush Hub, Yes/No for KTM 530?

[mrjonj]

I tried it on my 08. have 640 hub laced to a 2.15 530 rim if you want to buy I am open... Even better if you pay for shipping for both i will trade it for a clean 08 or newer ktm 530 complete wheel (no sprocket, no disc). Is heavy and keeps the back end tracking up and down whoops when should be bouncing across the top. Weight does add an added sense of traction though. Cush hub = 2 to 4 mm of dampening, drive chain has 1 inch knobbies, 4 inches of tire at 12 psi, and play in chain. Between the huge amount of play in rubber tire I am not convinced cush hub adds any real benefit.

Everyone sure keeps commenting on how heavy the 640 hub is. I can feel the side effects of a heavy tire but didn't think the hub would be so noticable. Doesn't sound good for my whoops. Rad. Manufacturing makes a light weight billet unit with small rubbers/ hub assembly.

I have a RAD cush hub with a 2.5 excel via heavy duty stainless spokes as a second rear wheel for my 530. The hub is light and extremely well made (its very similar to the KTM 950/990 standard hub) but I can't feel any difference when riding compared to the stock wheel. The only reason I went with the cush drive hub is that I wanted a second wheel for the more open/faster/longer rides and all the Aus Safari riders swear by them.



On the dirt it doesn't realy matter what rear wheel your running, as long as your having fun.

I don't think the RAD Mfg hub that Woody uses is any lighter than the stock Adv one, at least another member posted that's what he was told. Being made from billet it should be stronger, though.

LC8TY, if there was such a thing as wheel porn, you would win!

love that pic.
wish i was there!

I have seen one smaller than the equalizer that Rad sells now. It only used small rubber donuts rather than the stock style rubbers. Google search showed nothing.

Thinking it was an earlier style. Or i'm crazy.

Does the RAD cush hub use the stock KTM rubbers?

Your not totaly crazy, Talon cush hubs use the small donut type rubbers. I had one on my old 950 and turned the donuts into miniture bite sized pieces in no time.

I'm not sure if they are exactly the same as the KTM but are very close.

That doesn't surprise me, the rubbers certainly feel and look less substantial. I just took a pic as a comparison (Talon 950 SE wheel):

Dave Hopkins claims to be doing one output shaft a week due to ruined slines from DS bikes.

I have one of the "new" kush sprockets

spat a rubber out after 2 hours light trail riding with a tiny lil bridgestone 19" rear

what they have done is put a keyway into the rubber peice and sort of key it together with glue problem is that the keyway is only on the outer edge of the rubber, needs to go all way around I think.

Im putting steel washers either side of each rubber held with 5mm bolts to stop them comming out, will be heavy and the tiny rubbers can't do much

I like the look of the cush hubs with really big rubber bits, surely bigger rubber bits = more beterer cusioning

I emailed them a few days ago and they got back to me today:

 
Hi Michael, 
 
Sorry nothing now until at least July. The design was changed and they are currently making all the new tooling, sorry for the delay.

Are you all out of the KTM 530 47 tooth sprockets? I want to order one.

Maybe they are making some changes that will fix the issues - contact them, maybe they will make things right by sending you one of the retooled units either free or at a decent discount...

I still plan on ordering one (in july now ) - if I can remember I will report back on results.

I dont want to hijack but i also have similar questions. The more you read up on something the more you get convinced you need it, anyway.

I have a 2010 450 exc (375k's, new this spring, also new to ridding) rekluse pro, 14/52 gearing and find im using it more on the street then i thought i would. Like taking it to work only a 15 min ride but sure beats ridding my big pickup, not to mention the price of gas in Nothern Ontario, and also going for a quick ride somewhere.

Is the damage to the trany something that will just go, or more of an accumulation of miles over a couple of years. I just love my bike, dont want to hurt her.

It also sounds that Cush users only have them for the road, would newer riders notice anything off road??

Thanks, time to go to work.
