Hey guys, long time lurker, first time poster,

I've had my cbr tri colour for a month now and when I first got it I took to the back streets for a strap. I noticed the clutch was slipping in high revs but blamed it on tapping it into neutral or slow clutch release since i didn't know better. I changed the oil and replaced it with Motul 5100 10W50 oil and oem filter (the old oil was still in good nick). It kept slipping and found out why from a few pm's to studricho. So it's led me here with this topic. The fibre plates look fine, the grooves are still clean but the steel plates have me wondering. I haven't replaced a clutch in a cbr before and couldn't find any used steel plates on google that look the same as the ones below.








Steel plates (notice the small random silver scuff marks)




Friction plate (they all look like this and look fine)




Friction plates and steel plates.
Notice the difference in colour of the steel plates.


At first i thought the steel plates were heat treated which left them discoloured, but discounted this after seeing brand new plates. They look like theyve been through some really high temps to come out with those colours. My guess is they're warped and thats why there are random scuff marks from the friction plates because theyre inconsistent around the plate? But they look straight laid flat on glass.

I would of asked the previous owner, but they only had it for a short period and basically sold it for a friend. I've never had any other problems apart from this. I can still ride around in low revs with no problems but when i open up the throttle in lower gears, there's a 40% chance that it will slip.

I'd appreciate any advice or opinions on this or even if you've had the same experience. It'd help heaps.


p.s. the new site looks awesome :D[hr]


And the first friction plate (since i'm only allowed 10 images in one post)

Update: Had the plates checked out by a Honda guy and got told that motul 5100 is causing the clutch slip since it's semi synthetic. They reckon I should be using motul 3000 instead since its mineral based. It's got me confused since I keep hearing 5100 is what you should be using for a cbr250rr:s

What do you think?
