CushDrive Sprocket System - Bolt On Cush Hub

As a long-time lurker and member, I thought I (rather than just having a friend do it for me) would be the one to announce the new product I've been working on, a bolt-on cush hub for enduros, dual sports, and lightweight adventure machines otherwise lacking them.

It's called the CushDrive Sprocket System, and it gives you all of the benefits of a cush hub, without having to custom-adapt a different hub to your bike and all of the hassles that come with it.

It works by isolating the sprocket from the hub with the use of 24 replaceable urethane bushings, and allows for different sprocket sizes from 44 to 52 teeth.

It is early days over here, and while the product is made in New Zealand, we're assembling them in the US and will be slowly bringing manufacturing over to America as demand increases. We've had some wicked riders beating on them in every situation ranging from long-distance pavement touring to hard enduro without issue.

I think what will really separate this from the other attempts at a cush sprocket is the no-nonsense design. Bushings are held captive between alloy, the sprockets are steel, and everything else is quality aluminum.

You could beat this thing with an iron club and it would still continue to function. Best of all, we're warrantying the bushings for 10,000 miles or five years, so this really isn't a throw-away item when the sprocket wears out.

If anyone has any questions, we'll do our best to check this thread as much as we can.

I'm down with this!

Brilliant Idea. I hope the ADV community will get behind this product. I already add cush hubs to all my bikes, for big cash, but the next one will have this product. Cush is the ONLY way to keep you small bike alive on those 1,000 mile adventure rides. My tires last 30% longer too.

It looks a lot like the one from Australia

Good eye!

If you're referring to the MotoMox product from New Zealand, it is the same unit, though we'll be making some changes (anodizing, bike fitment) over here.

Thanks for the kind words! Your tires will definitely last longer, unless you're Graham Jarvis, then your tires never had a fighting chance.

Everything lasts longer, chains, sprockets, c/s sprockets, there's a reason street bikes have cush drives. I've wanted something like this for quite a while, especially on my RFS Beta which was incredibly happy on the pavement, but I knew I was tearing up everything inside, so it really kept me from using the bike to its potential.

I had looked at this product before, having searched it out. I was interested for my '17 Beta 500. What kept me away from it up to now was a fairly low hr/mileage service interval listed (50 hrs / 3k miles) and the sprockets were custom to the drive so if I wanted to change sprockets I had to custom order them.

I like the concept and there's a need for it. I was hoping to find a cush drive front sprocket to solve the problem. JT sprockets is now making them but after going through their catalog and contacting them directly they don't have one that fits the Z-15 spline for the Beta or KTM engines. You can get them for a Z-13 spline which fits both DRZs and KLRs. That's the slick solution as there's no additional unsprung weight on the rear wheel but..... not an off the shelf solution at the moment.

I couldn't find a price for replacement bushes or sprocket rings. How much are they running?

I saw this photo of your setup on a Beta which is what caught my attention. I might be interested in a setup with a 50T sprocket ring.

We've updated our service interval. There's no need to tear anything apart after further testing and real world abuse, Paul in NZ hasn't taken that down. We now have multiple real-world users at 10K miles without issues. We just advise to check for play or looseness when you're changing tires or oil. Obviously AA/hard enduro riders are going to have increased service intervals.

Most importantly in the US we are offering a 10,000 mile or 5 year warranty on the bushings. I doubt most will put that many miles on their enduros, and if they do, replacing some bushings will be easy-peasy compared to the 4T head work you'll need to be doing. :)

It is definitely an increase in unsprung weight, but it is fairly central mass, you'll feel it less than an HD tube.

We haven't listed a price for the rebuild kits in the US as we're including them in our warranty. Email me for a special deal on a CushDrive system with an extra sprocket, we'll take care of our fellow Beta riders :) - matt@adventure-imports.com

Yes it is Iwhen I was getting my cush drive rear wheel from warp nine I told them they should import when it became available . It seem like you got a very good product good luck

Thanks a bunch for the update! That's great news about the durability. I think even replacing the bushes at 10k miles would be quite acceptable.

I'll shoot you an email.

The bushings also really easy to replace and it can be done trailside with basic tools if you're on a long trip—say riding from Prudhoe Bay to Ushuaia :)

Looking forward to your email!

Will you offer smaller than 44 teeth? Drz sm

Not at the moment, if you require something smaller we suggest changing your front countershaft sprocket and then ordering a rear sprocket to the desired ratio.

Do you have to buy the sprocket and cush adapter for each rear sprocket size you want? Looks like an updated version of the Kush system from a couple years ago, but with captured cushioned pieces.

No. The sprockets are completely interchangeable and it can be done with basic tools. They'll be around $50—we're still finalizing pricing as we hope to bring the cost down on them.

If you have multiple bikes, and you buy multiple CushDrive Sprocket Systems (say for a KTM and a Kawasaki), the actual sprockets will be interchangeable between the brands as well. (Just to clarify you still need the correct kit for each bike)

Do those JT rubber cushioned front sprockets actually provide a rubber cushion between the countershaft splines and the sprocket teeth ?
Doesnt appear to in their pics

Doesn't look like it. Their literature suggests that the cushioning is there to buffer chain wear on the sprocket rather than to protect the countershaft splines. The stock XR650L front sprocket has that feature and it doesn't do squat to protect the countershaft splines.

What's your expected timing for additional sizes of sprockets? I have a 2011 Husqvarna TE630 which desperately needs this product, but your listed sprocket sizes don't match. (156/136).

I thought that rubber just made the system run quieter as the chain moves over the rubber? The CS is not cushioned from inner shaft contact to outer tooth like this sweet setup.
