Hi all,

My '99 M900S with std clutch is making more and more noise out of the clutch (has done 22k). I am considering replacing the basket with an aftermarket alloy basket and alloy plates. Would you recommend this or is it better to stay with the std steel one?

Thanks,

Otto

It's a Ducati, live with it. I have an '01 with 37K miles, yes, clutch is loud with an open cover, but that give it character.

It is only worthwhile if YOU deem it worthwhile. Is it necessary? No.

But if you live in the city centre of Amsterdam, where people get lynched over waking up the neighbors with some friendly Termignoni fire in the morning, it is a good thing to at least have a clutch that does not hit the Richter scale....

I think I'll just settle for a modification of this one, so it'll be more quiet.

I like that mod, anything to lighten rotating parts give you quicker throttle response.

When I recently bought my Paul Smart, I went crazy with the $800 dry clutch set up. I so badly wanted to buy a lightened alloy clutch basket. As a friend pointed out to me, "hey the bike came with 400 miles on it, why don't you ride it until it's wasted", so true. So I backed off. I might still sneak 1 on the bike as cash permits.

I say do it if you have the money to spend and replace it when necessary. The comments I received was that I could expect about half the life of stock. 1 thing to keep in mind as folks say "do it, replacing with a lighter clutch will let the bike spin up faster", well they spin down faster too. No more engine braking with lightened flywheels and lightened clutches. I love engine braking. Letting off the accelerator to feel the bike pull down and then downshift before needing to use brakes. You lose that momentum with lightened engine bits. That's why they come with the flywheels and counterweights that they do.

I highly recommend if you make the switch to definitely buy alloy plates as well. No reason to ruin the new basket. I recently converted my Norton Commando to a Steve Maney belt (ooh it's kandy), about twice the cost of any other kit. But oh so nice. He engraved my last name on the back of the clutch basket with the CNC. Tacky I know but I loved it. I'm so sad I cannot find Kevlar plates in alloy. Actually I can't seem to find any plates in alloy so I've not been riding the bike. The belt drive is the best thing I've ever done to the bike, even more satisfying than the engine rebuild and new isolastics, but I don't want to run the steel plates.

errrrrrrrrrrrrrrrrt! put those brakes on. there's a difference between expected clutch noise and a worn out neglected clutch.

i was in the same boat as you caferacermike, i pieced together the ideal clutch assembly i wanted and ended up being $780. i ended up scoring a low mileage yoyodyne slipper for under $500.

you're wanting to update your clutch assembly Ottodesmo. check out ducati.ms and ebay. i've seen multiple ads where people are selling new and lightly used parts for cheap. if your not i a hurry. piece together a nice clutch on a budget.

i always buy used if i can.

Done that mod. Had to change the clutch plates as they were worn on BOTH sides of the tangs. Basket looked OK but not mint.

As I gathered infos on new clutch pack and else, I realized that I should switch to alloy plates and therefore change the basket for an alloy one also.

Found this site pretty instructive: www.desmotimes.com.

Bought stuff from him and eBay. Did the job myself (saved a lot of pennies that I putted on better pieces).

The basket by it self saves you like 2-3 pounds of rotating mass. Nevers regretted the move.

Good Luck!

Thanks for all replies!

In the end it turned out that my basket and plates were still OK, so I chose to have the clutch modified by a Dutch specialist (Biggelaar). By adding a spring mechanism the plates are ever so slightly pressed together with the clutch released, so that the clutch does not wear and the knocking sound is gone. As a result, the bike is much quiter with an open cover, and the ringling sound with the clutch activated has improved a lot.

In short: I'm very happy with this mod!
