Barnett clutch wear vs. stock

I have used three barnett clutch packs now and have been satisfied with performance while they lasted, but not enamored with the longevity of the clutch packs. I've been getting about 4.5 to 6k mi. out of a set of barnett plates and have been able to get up to 15k mi. out of a Ducati clutch pack.

I'm not talking about drag racing, but commuting and sport riding in the mountains.

I'm in neutral at stops and don't abuse in any way.

What's everybody else using?

How many miles do you all get?

24,000 miles on my Barnett clutch in a 900 motor -and still going...
20,000+ miles on the stock Ducati clutch 1098S -and still going...
It isn't because I ride easy either, ANYONE who has ridden with me will tell you I scoot with authority.

If you're getting les than 10,000 miles I would look more at your technique or installation and less at the clutch manufacturer!
(unless it is a slipper clutch OR a track-only bike -those will have shorter lives)

Hey Larry,

I used Barnett plates on my race/track 749 and these lasted 1 trackday and 1 race. I've since gone back to Ducati OE plates.

Thanks Nutts. Sorta what I suspected.

I've been riding a good while and on Ducatis daily for just shy of 30 years - definitely not my technique and installation is pretty well idiot proof.

The last two sets have been the red material and the most recent set of friction plates didn't have friction material full circle, but only glued on tabs of friction material with metal showing between the friction pads. I noticed the friction tabs were very thin when I installed them. I'm thinking they're more race orientated items rather than for everyday use.

20,000 miles is a pretty good number of miles on a 1098.  I would have though that is an extraordinarily large number of miles for a set of clutch plates too.

Not sure if you use an open clutch setup, but I think it's pretty well established that Barnett plates are more affected by water corrosion than the oem plates. IMO a single night parked in the rain does the equivalence of hundreds of miles of wear to a Barnett pack.

Those red material discs are shite.. a friend is trying German sourced aftermarket discs but isn't happy either.

The slipper clutch in my 749 works much better with the stock items. Have you put in a slipper clutch on the black beauty yet??

in my experience and opinion, barnett is complete garbage.  mine started slipping after the first burn out (trust me, not my technique as i've abused my oem clutches in my other two m900's a lot worse).  went back to oem and never been happier.  will never buy barnett again.

We use Surflex and Ducati OEM clutches in our own bikes--even though Barnett is less expensive.
