Clutch issue - for the CB schism

Is that because it's too hot?😁

Although I'm no fan of the 'tack another thing on the spec list for no good reason other than to con people this years bike is better and you need to change' marketing that has resulted in slipper clutches going 'mainstream' ...... (and breathe) ...... it could well be nothing to do with the slipper part of the clutch and just that the design is more sensitive to 'overheating' and the type of riding/amount of clutch slipping that you guys were doing just exasperated the issue.

 

Some of my bikes, most noticeably the MT660, have been prone to the clutch lever biting nearer and nearer the grip after lots of clutch slip (who said wheely practice? :whistle:) and perhaps older/thinner oil adds to the issue. I wouldn't have thought that oil level just above the low marker would be an issue but again, that depends to some extent on the design parameters of the motor and clutch and perhaps, just perhaps, the CB is a little too near the envelope.  You would have thought however that Honda knew the middleweight would be a fair bet for a few commuters, and hence lots of slow speeds and clutch use, and engineered it accordingly :hmm:?

I must admit that I am in a state of denial that a Honda could go wrong!

Please let us know if you have any further clutch ( or any other) problem as you now have me concerned.

Rocker, I wouldn't worry, Honda have sold thousands of the things and the issue hasn't been common place, and Glendon and Andy's  experiences could be one offs. Certainly Andy has been giving the bike a bit more stick than is usual and even he's only reporting 'an odd feel' not a real problem. It would be interesting to hear whether Glendon gets a repeat and, if so, under what circumstances and whether the clutch returned to 'normal' after a wait?

 

Just go easy on the wheely practice in the meantime :thumbsup:

I took mine out for a brief run to warm then motor so I could check the oil. It felt different but I could not say exactly how. The oil was on the low side though - just above the low level mark. When it locked up I was not long out of a crawl through the centre of Warwick. Could simple over heating be the issue? If so I am not happy!

 

Is this the new bike with the slipper clutch?

 

I don't know the answer, I'm just curious.

Yep. To be specific it is the red ones - both Andy and I bought red ones. Rocker has a white one and that is fine:devil:

No need for denial, from personal experience they do go wrong, just not very often.

Ooh a bit of extra power, we would have killed for that on our mopeds at 16 years old

If there is anything, it is slipper clutch related. Probably not the slippy bit even, but my 2018 F had nothing comparable.

I think slipper clutches do feel a bit different, could just be that? Mine feels a bit strange sometimes too.

Mine went from normal to unworkable in about two minutes, then back to working after about seven hours.

If it was consistent yes, but nothing mechanical should be variable. The bite point in my case moves by roughly 3mm and in Glendon's case went off the scale, the cable going slack.

Don’t be too quick to write off slipper clutches as ‘unnecessary frippery’. They allow some among us to keep riding a manual machine when the alternative would be a DCT or T&G.

 

I freely admit that their primary function (avoiding a rear wheel lock up during ham fisted downshifting) is seldom required on the public road, or is it? Maybe newer riders benefit in the same way as ABS benefits us all?
 

But leaving that aside, the light action is of immeasurable benefit to old codgers like myself and Glendon (who should have bought a Triumph anyway.. ;):) ) as it allows us to keep on. :niceone:

Aye, I found much to admire about Laverda machines. But lightness of controls wasn’t among them.. ;)

To be fair I think mine seized because the oil filter disintegrated as it wasn't a genuine product ( in my opinion ). Genuine Honda part according to the supplying dealer, should have taken it up with Honda UK, but didn't.

My boy picks up his CB500X next week, will keep a weather eye on this thread.

Well Ruby was booked in to the dealer this morning. I am about 30 miles from them, along a cracking B road then a fast dual carriageway. The weather was Biblical, as in Noah and the flood biblical and the clutch did not feel good - in fact it was stiffening up. By the time I got to the fast dual carriageway bit the clutch lever was not returning properly and I had visions of the last couple of miles, through suburbia, being a nightmare. Anyway, pinned it down the Norwich outer ringroad for ten miles and then peeled off onto the superb, though pointless Northern distributor (doesn't distribute anything as it was never completed) at which point I realised the clutch was back to feeling utterly normal! So I arrived at the dealers and had to tell them that it was buggered but now seems fine.....So the dealer just phoned - they cannot find a fault! Had the clutch cover off - all seems well. This totally undermines my confidence in the bike.:(
