Clutch too stiff. What are my options?

I messed up my left wrist about a year ago and ever since then, my wrist kills me after I ride for about 30 minutes. How can I make the clutch easier to pull? Is that what the slave cylinder does?

yes, an aftermarket slave will help by about 20% i'd say. see yoyodyne or evoluzione. i can recommend the evo slave. (more) adjustable levers can help; CRG roll-a-clicks are good.

radial clutch master cylinder will help a lot. and cost a lot more $.

Don't forget changing the slave cylinder which made a huge difference on my S4. I bought mine off eBay from MPL Tuning from Germany along with a billet vented clutch cover. Great workmanship and much cheaper than changing the master cylinder.

+1 on an aftermarket billet slave cylinder. We have one for $125.

But, if you really want a ridiculous easy clutch pull-- get a Surflex slipper clutch. the street/track version has softer springs...It isn't the main reason why people get this slipper clutch but it sure is a nice side benefit.

It's  bit more work, but it's still doable.

Best to do it during an oil change as you have to drain the oil to pop that side cover off.

Make sure they're 2 opposing springs. and I'd recommend using one of Chris K's gaskets for that cover instead of gasket glue. 
You can get it here look under "Oil/clutch engine cover gasket"

I've been running only 4 springs on my dry clutch for a while without issue.

Worst case your clutch will slip (test at about 60-70mph in top gear) and then you'll have to put them back. But I think you'll be fine.

Best of luck!

I've been running 4 springs for about 4,000 miles and haven't had any problems either.

Amazing how much lighter the clutch effort is with an aftermarket slave and 2 springs gone.

Start working out your forearms ;D....yes it's not quite as light as Japenese bikes but I would not consider it hard by any means.

You may want optimize the lever angle - I found after installing Cyclecat clipons the angle of the clutch lever is more natural for my hand - you may want to consider removing the locater pin and adjusting the angle of the lever - the effort is not thar bad.

Guy Martin told me about that little trick. I thought it was a great idea until I tried it (m900 w/ dry clutch btw) Clutch pull was heavenly. But. . . it slipped badly in the upper rpm range. Im running a stock basket and pressure plate, w/barnett alum. plates.

you may have a problem with your bike,or your arm if you have such difficulty with the clutch. l`m serious amigo,have you ridden any other bikes? Ducs have a very easy clutch pull normally. Strong arms can save your life on a bike. ln the very early days a cyclist was a man of steel,a daredevil mechanic.The superbikes of the seventies had clutch pulls that would bring tears to a longshoreman,especially after installing the Barnett clutch.You`ll be better off if you just get used to it because power steering is out of the question :)

I disagree.

I felt the clutch on Guy Martin's race prepped SBK, and it was like nothing. -2 springs, radial pump clutch master and an aftermarket slave. It felt like there was 2 springs total holding things together, its that light.

I run stock pull on my m900 and ive always been fine with it, even in stop n go traffic.

However, now that im getting old (ill be 30 in a couple months) i find the joints in my clutch hand don't like the stiff pull. Not sure if im going to do anything about it or not, but I certainly wouldn't want to hear "tough it out" as an option. . .

Unfortunately, I don't think getting used to it is an option. I owned my bike for over a year (commuting everyday) and never had pain. I think i have the strength since i ride so frequently. It's only been the last year (since I messed up my wrist) and only on long/weekend rides that it hurts - and it's not a muscle pain - it's a sharp pain deep inside my wrist.

Anyways, I'm going to try pulling out a couple springs next time i change my oil. (cheap mods first) Then I'll swap out the slave a couple months after that if it's still not helping.

Thanks for all the ideas/help!!

I commute in Tokyo area traffic daily. It's nothing anyone in the states could even imagine. I was having issues with the pull on my clutch as well. Not to say I am weak, which my hands/forearms are not. It's the repeatitive motion that hurts.

I installed my MPL slave picked up off ebay. Works like a champ, and it was fairly cheap compaired to the units sold at the dealierships. With that said, it's nothing like my wife's Hornet 250, but I don't expect that out of a Ducati. It is, though, much better then stock now!
