We measured a brand new set of EBC CSK12 clutch springs for length and thickness to compare to the stock clutch springs before they went into our CX650E:
Stock length – 39.50mm:
Stock thickness: 3.28 (probably not super accurate with the calipers…):
So how long are the stock CX650E springs? Well, we don’t know how long these ones were when they were new nor how old they are now but the current length is 37.8mm:
Stock thickness – well this at least shouldn’t change – 2.89mm:
