Cycle X 4 friction Clutch System?
« on: February 16, 2016, 02:34:11 PM »
Got an email today about this. Was wondering if any of you think its worth time and effort to R&D a similar setup for the 550?

I think Cycle X has pretty much given up on developing new 550 parts (according to one of their salespeople).  The mainstay of their customers ask for 750 parts.

Yes I know, I meant if one of us made one. It's practically just a spacer.

I wonder what coating they use on steel plates.

I got a set of steel plates from them once with the coating and they sent me used plates with some serious rust pits they just sand blasted and coated. as soon as i opened them up and rubbed my finger on them the coating just came right off, ran them for about two weeks before my new ones from barnet came in because i was un saticfied with cyclex, when i pulled them out the coating was gone. If i remember right i talked to someone at cyclex and they told me it was a jethot coating i would think some sort of ceramic coat.

Interesting.  I've had some slippage on my 836.  It would be nice to avoid this on my 550/650 build, but I think the clutch pack is different on my 650 motor than even a 550.

Std CB750 clutch pack and harder springs (EBC, Barnett etc) work well. Not the short thick springs.

My CycleX coated steel clutch plates wore out in short time turning my oil metallic. No thanks. I still have the pack somewhere and it made me hesitant to buy CycleX parts.
