I'd say he's pulling that number out of his ass. They've only been around for a year or so. I seriously doubt anyone has put 200,000 miles on one yet.

200,000 km is only 125,000 miles.

Still, I don't disagree with you about the 1 year versus 125,000 miles, buuuut, you just never know.

Interesting thoughts ... all around. My driveshaft was replaced less than 1,000 miles ago ... so hopefully I won't have to worry about this for 50,000 or so. I'd like to think that these are the wave of the future ...

If for no other reason than to make Brad rethink his position on paralevers.

I'll wait ... by the time I have 50,000 miles on mine, I'll bet Stage's will be approaching 1,000,000 of constant abuse. We'll have plenty of hard data by that time.

Yup. The rear half of the shaft (at the front of the photo) and the front half are separated by the rubber dampener. Over time they get out of phase because the rear half twists in the rubber and doesn't return.

As for being out of phase, there's been a lot of talk that that's a problem that leads to failure of these shafts. There's also talk of the shaft operating at greater angles (say, compared to a R100R with less suspension travel) and that's the cause of failed u-joints.

There's also mention that out-of-phase leads to vibration.

All I want is a shaft that won't fail at 30K miles. I've had that for awhile (the current shaft is at 60K but I'm getting nervous - esp. given that it's so much more out of phase than the previous shaft) but if the OP is pointing to what's truly a better mousetrap I'm staying tuned.

There's a crazy new design that's supposed to be completely bulletproof. Here's a CAD image of the prototype

That'll never work. The shaft-jacking will pogo the rider into the next county.

Now that the topic of greasable u-joint fitted driveshafts is once more in front of us, I have a question... What kind of grease do you guys service these with? That would be HPM's, Bruno's and if it's been done yet, these new ones - I'm going to be having a look at my new one in the coming months - I might give her a squirt or two even though it's fairly new.

THe green stuff in my gun



I took HPM's shaft out when I put this new one in. It looks identical to brand new apart from being, you know, kinda dirty. Thats about 10-15K miles I reckon. No service since install.

If I'm to believe what people say on this forum, it would seem that you thrash your bike on a regular basis. Is this why you chose to go for the new style shaft over the HPM re-build?

In your defense, the shaft came with 'green stuff' in it. I might be looking around my airline's hangar for some nice red wheel bearing grease that is doing great service in our machines.

Actually i was happily satisfied with the HPM. I might not have bothered a change except one appeared by way of an RA contact that got it to me on on the probability that I might write a review of it of some kind for the magazine. SO I'm trying to hurt it I gotta say I feel like its a softer feel, whatever that means. What am I saying, its perfectly functional. CAnt tell a thing from the seat.
I have about a thousand miles on it.

Time and only time will tell, and having looked at it, I dont share the opinion that the upper main big circlip will see any real force. I dont think its a true bearing clip, yet. I mean I dont think it from looking at it, but use will tell I hope.

I put around 4K miles on it last season and can't say as I notice any difference from the original. No problems to date.

Me thinks that giving you a shaft to wring out is kind of like that old Samsonite luggage commercial - where they threw the luggage into the cage with the Gorilla to see if he could fuck it up. That's a compliment by the way. Did you see any literature about replacement parts in your packaging? I didn't and so I'm curious where you would get spare bits if you need it.
