I've got a 2018 350sxf that I've had for just under a year now and one of the only things that I don't like about the bike is the clutch pull. It's annoyingly heavy compared to my other bike, a 2015 250sx so I want to see if the DDS Clutch from the 250sx would fit in the 350sxf and work correctly. Long story short it does. You have to use the whole clutch pack (don't mix the fibres and plates) and the push rod from the 250sx. As soon as I got it together I took it for a quick ride and It's amazingly light in comparison to the stock 350sxf clutch, doesn't drag as much and didn't slip at all. I'll keep you all updated over my next few ride to see how it goes in the sand but if anything it engages with similar force to the stock clutch (tested on bitumen road).
