Anybody fully understand how it works? Not a DCT, characteristics of a quick shifter but also allows gear selection from a standstill. So basically you don’t have to use the clutch lever if you don’t want to? I’m a bit confused.

Didn't CZ have something similar, albeit mechanical. Clutch operated by the gear lever, so you could select first and pull away whilst waving 'goodbye'

Is it centrifugal? Doesn't engage until certain revs......

There was a thread on this a while ago I'm sure, with the Honda press release.

Its just a leccy actuator which pulls the lever for you AIUI. Doesn't literally pull the lever (ISTR it pulls on the crank/lever down at the other end of the cavle) but does the equivalent function. Thus any manual bike with a cable clutch could theoretically be converted to semi auto.

Edit: ere you go.

They did, and they may have copied it from Honda, Honda step throughs have a similar mechanical system.

The CZ operated from the clutch cable, you had to keep your foot on the lever and let it return slowly, or it would stall. No chance of a wheelie, unlike the C90....

Is the Honda system actually available on any bikes you can buy?

That press release ^^^ just talks in general terms.

As far as I can tell, you'd just twist and go to pull off and then you're away. Like having a helpful butler to operate the clutch lever for you, but otherwise just like any other manual.

I suspect Honda just developed it to be able to offer a cheap auto solution where DCT is too big/expensive.

The 2024 Honda CB650R has the electric clutch

There was a cam on the end of the starter/shifter shaft that physically pushed the clutch actuator on the RHS of the engine, when you used it, the clutch lever would go floppy from no tension on the cable end.

You could certainly wheelie the 350 by accident as using the foot clutch was like a light switch until you got the knack.

The neutral between 3rd and 4th was also actually meant to be there, for coasting.

They're a very, very odd bike. But they're frankly ludicrous money now. I paid a score for my last one.

its an added extra, but also it you do get it, you don't need to get it.

I wonder what its like, the boys on the CBR650r page I follow are wetting them selfs

Jawa / CZ did... and I could

I discovered the 350 twin could also pop a little wheelie when you let the clutch out, nothing happened and you remembered you still had your toes on the gear shift... and lifted off suddenly

"The system can be turned on or off. When the system is on, it automatically controls clutch operation and no clutch lever operation is required from the rider (excluding manual mode as explained below). Only throttle operation is required when starting, only gear shift pedal operation is required for gear shifting, and clutch lever operation is not required when stopping. When riding, however, hand operation of the clutch lever can move the system into manual mode temporarily, which requires the same clutch lever operation as a normal manual transmission. When the system is off, it operates like a normal manual transmission, which requires clutch lever operation in all riding states (starting, gear shifting, and stopping)."

I'm wondering how likely it is for the rider to get confused and do the wrong thing. Looks as if, if it's switched on, the worst that could happen is you use the clutch lever when you don't need to. But if you switch it off you might forget that you're not in auto mode and try to change clutchlessly in the wrong circumstances - perhaps?

I wouldn't mind betting Honda put in features precisely for that eventuality. I.e. you can't turn it off off and if you try and do a traditional clutchless shift it'll still intervene, even if it's "off".

Maybe.

That would make sense.

Triumph introduced it, branded as “Slickshift” on their 500 and 650 twins in 1958. Everyone hated it and it was dropped.

I have no idea who copied who.
