I see Brocks has them for 08-20. Schnitz has them up to 2024. So is there a difference? I have new tires on the way this week and wouldnt mind swapping new ones in while the wheel is out. I do know the sprocket come out of them real easy with the stock rubbers which means theres a ton of slop in there. Anyone used the Brocks on Gen 3?

I got a set from here that I won't be using because I picked up a set of CoreMoto wheels.


Make me an offer, and I can get them shipped over to you.

I appreciate it. I had already ordered should be here before the tires
 
I can sure feel the difference between OEM and the Schnitz rubbers. It’s like direct drive. No driveline slack. Does anyone/everyone balance their wheels with the Cush drive in place? I’ve always removed them when I’ve taken them in for new tires. I work out heavily for the month before trying to remove and replace them… :)
 
Paul at KPS is a wonderdul guy. I bought my Gen I rubbers from him, I bought my GEN III from him.

I always balanced my wheels with the cush drive, sprocket carrier with sprocket and brake rotor in place. I figure they're all a part of the wheel and they probably have an impact on balance.

My sprocket carrier was loose by the first time I took the rear wheel off to change tires on my Gen2. Second tire change, the carrier was falling out under it's own weight. I used Sensei cush drive rubbers purchased from MPS. That definitely made a very positive difference in the response of the drive. The Sensei rubbers made seating the sprocket carrier very difficult. I placed a piece of wood over the carrier and stood on it and that didn't even press the carrier in all the way. I pounded it with a rubber mallet a little too. I'm pretty sure torquing the axle pressed the carrier in all the way eventually. Guess I better have a look at that. Come to think of it, I did have a lot of wear on the inside surface of my front sprocket teeth. It was probably chain misalignment from the sprocket carrier not being fully seated. Thanks for the reminder. I'll be checking on that soon.

This tutorial might be helpful at least to show what I mean by the sprocket carrier not fully seating. It's the last pic and I see I later made the comment that there should be no gap between the carrier and the wheel hub.


And this too might be interesting to have a read and look. I bet that sprocket wear was from the super tight Sensei dampers I put in. @JeffSyh , I think you nailed it back a few years. Probably the cush drive.

Yea I am having the dealer do the tires and ill have them throw these in while they are at it. I have front pads going in there too. If they have them off may as well have them thrown in....
 
Hello, just chiming in here. I was looking for 1st gen cushes in red. What is KPS, and what do they cost? Thanks for any information.

It looks like he's now molding them in black, they were originally blue, and the others are red. That makes no difference. Paul's components are quality additions to your Hayabusa.

I actually have my original KPS Kush rubbers in the 2005. They last forever.

Thanks for responding. I'm not good at navigating this site yet. How could I get a path to purchase these? Thanks for the information.
 
Tap the link on the item I listed above. The link will take you to Paul's website. When you get to the KPS website, you will be asked to open an account. Put in your email address and a password and follow the instructions. Once you are done registering, then you can select the item in the link and it will take you to a cart where you will arrange payment, and Paul will then organize shipping and send it to you. If after registering you lose track of the link, put cush rubber in the search box and it will take you to several items one being the 99-07 model part number. Select the item and off you go.

I did send Paul an email just to be certain these are high-performance units for early Hayabusa. I'm certain he wouldn't have them on the website if they were not.

He doesn't usually sell anything that isn't higher performance.
