Hey all !
I have an issue with my 2018 GSXS 1000F clutch. 6770 miles on 4 mo old bike. Clutch is dragging when lever in when warm. Free play is proper. Neutral not achievable at a light and bike creeps forward. Bike is at Berts Mega Mall since Monday, 12/17 with no phone call or answer. Very disgusted with them. Has anyone had any clutch issues? I've talked to many friends with bikes. No clutch issues. Even the guys seeing track days. I've been told Suzuki will most likely not cover the clutch problem before it was even looked at. Glad to know they make a perfect bike and no need for warranty it seems. I asked Neo the service guy if he had seen any GSXR's or GSXS's with clutch issues, he said no! That says something doesn't it?


Anyone have a suggestion for a good Suzuki dealer that doesn't have a ****ty service department in So. CAL? After reading yelp reviews of all local dealers, its amazing to me they are still in business. Lots of "avoid this service department" is not the most appealing thing to read when deciding to take a bike in for warranty repair.

side note: not my first bike! 6th actually, still riding my '07 Yamaha FJR 1300 with 62,250 miles. Dealer suggested possibly I did not use clutch properly. Didn't think I would hear that!

If the free play is adjusted properly as you say, that is definitely very strange. Did you change to a different motor oil with additives possibly? Will be interesting to hear what others here have to say here.

Am using the Motul semi synthetic 10/40. Plenty of people running that with the GSXR's and no issues. It's a very high quality oil. Can't imagine having an issue with that. Anyone else experience an oil issue with their clutch? My guess is that their is a clearance issue and is more noticeable when hot due to expansion. Or possibly an issue with the clutch drum or components. Perhaps a lack of lubrication at the clutch drum? Not a common issue as even the lousy service writer said that they don't see issues with clutches on these or the GSXR's. That's kinda of a giveaway that this is not a normal issue and that something has happened. Looking back, shifting has gotten a bit harder. Not as silky smooth as it was. This certainly shifts softer, smother than my other bikes. Although not at the moment.

Not knowing anything about the GSXS clutch in particular, I'd suspect a warped disk. If any of the disks in the clutch pack have warped for any reason, that could easily result in a failure of the clutch to completely disengage when the lever is pulled in.

Wow. Sounds totally out of character to me.
Just to be certain; you are the original owner, yes? No chance that some dousche bag bought it new and flogged on it for a month only for it to be traded in and it fell into your hands?

I had some free play adjustment issues from brand new to first service (which is where the tech pointed it out) they adjusted the cable for me and it's right now. Also, I don't know how far south you are but Fred Cummings in Kern County Bakersfield area has always done me right and will submit a claim no problem. Most service departments get bad raps because nobody takes the time to write a good review. The real issue is Suzuki and their quick to deny claims stigma...."perfect bikes" remember haha

Does your bike have aftermarket levers? Maybe a pull ratio difference?
I've had no problems with my bike with stock or Pazzo levers, although I have also done some basic adjustments for my preferences and the different levers.

I think oldjackbob is on the right track - warped clutch plates most likely, from the symptoms you described.


It could have been caused by something as simple as a cable in need of lube, too. If it has too much friction, it won't "release" fully. And if it doesn't release fully, you can get clutch slippage and warp the plates. Clutched up wheelies can be hard on the plates, too. As can 'quarter-mile' starts (doing a lot of 'stoplight to stoplight' racing there in So. Cal?) If the shop is no help, buy and install a new clutch cable and see if that doesn't solve your problems. The cable is a braided line and perhaps some 'strands' have let go and now when you pull in the clutch, it isn't fully separating the plates? It's a long shot, but it is a relatively cheap thing to try and might get things sorted. If it doesn't do the trick, then it is probably warped plates and nothing else is going to fix it other than a new clutch pack install.


Oh, and to answer your question, the GSX-S1000 isn't known to have clutch issues, which is a good thing, but in 2018 Suzuki did switch to a 'slipper-clutch' on their USA model bikes. Maybe that is causing issues we haven't seen before? I'm just sorry you are experiencing problems. That's frustrating.

Hello a2002lover...any updates? Looks like you haven't even logged on to the forum in a month. Curious what the outcome was to your clutch issues. Give us an update when you get a chance.

Just a reminder for the newer Members, that there is a design issue where the clutch cable can wear where is passes over the radiator tank.
There is a long thread on it it pictures and solutions if you search here for it.
Also, that Dealer should check that the clutch cable is/was routed correctly as per the Service Manual. There are settings that can be checked as per the manual as well.

Suzuki USA should be honouring their lousy 1 year warranty. Do the lemon laws apply to this case ?
Wonder why your US warranty so short ?
To lower the selling price point. Australia has 2 year's, UK has 3 year's I believe.

Update on Clutch issue. Found that the dealer was correct. I have not had any issues with the clutch dragging since the oil change back to Suzuki standard oil. I hate to admit it! No other items were done at the dealer other than that and confirming settings of freeplay. Have put 1600 miles since occurrence and no issues. It seems that the motul oil in this bike is not liked by the clutch. Well, frequent oil changes and factory Suzuki oil on the shelf.

Good result.
I would not expected a Motul oil which I suspect is the 5100 semi synthetic 10W- 40 used to cause issues as I have used it myself in the past, till I found it not worth the double cost over basic mineral oils of the same grade based on my use.

Suzuki don't mandate any oil other than what they say in the Owners Manual.
That Motul oil has been around a long time as it's got a range of S grade service rating going from the very old oil SG standard upwards.
Cars from the 1960' and 70's need the SG grade for the extra phosphorus to protect big end bearings from undue wear.

I tried to attach the info below in a PDF file, but as it was 24 KB, it failed as the Forum limit is a lousy 4 KB lower at my 20KB file .
So I cut and pasted it. It certainly reads OK for use here for the GSX-S1000 that I can see. Any see a problem ?

I just did an oil change to Motul 5100, no clutch issues but then again I don't hardly ever actually demand any real power from the engine.
