Cush drive rear sprocket

wouldn't it be easier to get a cush drive rear wheel from a ktm and make custom spacers?

I would say that bolting a sprocket on would be easier than sourcing a cush hub, fitting special spokes, and making custom spacers. But I am biased. ?

Sourcing a complete used KTM wheel with custom spacers would be one option. If you were building a super moto it could make more sense if you wanted a different size rim or a spare set of wheels. But if not, then I suspect the Mox setup would come out cheaper and easier unless you had the wheel already.

You are 100% correct. I just called my local wheel shop and those cush hubs are more than I thought. Just the hub is over 500 bucks. If you shop around you might find one for 400.00. I'm going your route as soon as I have the cash. Thanks for posting this thread Dan. And another big thanks for Mathew the distributer for coming on here to give us info.

I'm sure there are a few guys that might squawk about weight. Right now that's the last thing I'm worried about. My goal is to keep my Beta at 360lbs or less ready to ride.

Cush hubs definitely aren't cheap! Weight is increased, over a alloy sprocket and non-cush hub, but if you're running on the street, and building the bike for it, you're probably going to be running a steel sprocket and a cush hub, which can really weight the bike down.

After a 120 mile dual sport ride last weekend I'm extremely pleased with the cush sprocket. It really does smooth things out and I find it works better on hard pack dirt and rocky stuff allowing better traction and less drive line judder in slow corners.

 

I'd buy it again for sure, at least for the kind of riding I do frequently. The last ride was about 30 miles of rather fun pavement in the canyons to get to the start of the dirt, typical. All told it was about 50/50 dirt pavement.

 

We rode from King City over the mountains to Hwy 1 on the coast.

Boy this sure turned out to be a bummer. Good thing I measured. When I was getting ready to hit the purchase button, something told me to measure my sprocket. The ID/PCD size just sounded too small.

Sure enough it will not fit. The 2012 Beta has a completely different sprocket size. Mine is a 136ID/156PCD. I sent a email to Matt, But I don't think it can even be special ordered. The 2010-2014 Betas have really strange sizing.

I've literally just gotten off the phone with NZ about getting these made. Apparently Beta wasn't officially in NZ until 2012, and they all have the "new" ID/PCD. We are working on making this happen.

Thank you for the prompt response and working on getting them!

I was doing some service work on my Husky TR650 that has a stock OEM style cush drive. I weighed the cush drive assembly (everything including rubber cushion blocks with a 47T steel sprocket), it came out to 5.38 lbs about twice what the Mox cush sprocket weighs (2 lbs) over a bare aluminum sprocket.

I really think this cush drive sprocket is going to take off in popularity. I just hope they get one sized up for my Beta soon. Another hope is Mox sprockets stick with steel teeth for longevity.

It sounds like they are working on a inner hub to match the earlier Betas. It seems like MOX is pretty heavily into supporting the Betas. I see the issue though that the earlier bikes weren't imported over there so they don't have access to test bikes.

So far I think all of the sprocket rings are steel. Both of the ones I have (48 & 50) are steel.

Ths is an old thread but active thread on ADVrider says the US company selling the NZ cush sprocket has stopped due to problems with the NZ mfg. A few left on close out

^^ Thanks for the heads up. I read about them stopping production and thought they were gone.

I've read reports that the rubber doesn't last (Aussie on the 'other' site).  That might have been a manufacturing issue, perhaps the reason they stopped....maybe a design flaw.  No solid facts.

Just ordered their last 49T for $136. for that price, I'll take a chance.

All they have left for betas are 2-51T

Wow, this is bad news. I really like my MOX cush sprocket and now when it wears out I will have to see about custom making replacement chain rings and the cush elements.

I can handle this when the time comes but it really sux. I might see about pinging MOX directly in NZ about a spare set of cush elements. 

Fortunately given the miles I typically put on this bike I think the chain ring will last a long time as it's steel, but the cush elements I'm not positive how long they will last.

These are not very technical units, very easy to reverse engineer and manufacture. The challenge is what is the real demand for these???

It would be nice to know from MOX what exactly is going on.  Maybe they don't hold up as well as they had hoped, maybe having problems manufacturing.. maybe they're in the process of selling to a larger manufacturer?  I noticed the 'blog' on their website still has the default Wordpress posts... which is very odd..

[DCrider]

The ADV thread has a tad bit more info from the US seller as he is active on ADV, but basically just said MOX was slow to reply/send stock and there were lots of QC problems with what they did send, so they were not making any $ and did not want to be associated with a poor quality product.

That would fit with this statement on their website:

Quote

We don’t make our stuff in China. It’s made outside of Christchurch, New Zealand by a guy named Paul, who’s a lovely bloke. On most weekends he’s out riding single track on his Beta XTrainer, presumably competing for right-of-way with New Zealand’s three-trillion sheep. Each and every CushDrive Sprocket System is assembled in the US from Kiwi parts, to ensure each riders gets exactly what they need.

One guy making them?  Don't care how 'lovely' he is.. without quality control and proper manufacturing...well.  Hope those who purchased can make good use of them and somehow fab up parts.

The idea seemed pretty cool, but execution....meh.. Quick...somebody patent it and take it to Shark Tank! ?

[randysoo]

I think the steel chain ring will last a while. getting a line on replacement cush polymers would be nice. I only ride 2 or 3 street heavy dualsports a year so hopefully it lasts.
