Maybe this was already shared, but I just saw this video of the TY-E electric trials bike. Totally different sound with a clutch compared to the automatic and clutch-less Alta. Excited to see the trickle-down into other motorcycles.

That's cool! It's just a matter of time.

I think the clutch would purely be there as a means of traction control. It seems like a way more precise way to control your power out put then the awkward movement of twisting a throttle. I imagine twisting a throttle may throw these guys off balance too much as their centre of gravity changes

I’d much rather have an E-bike with a clutch (for the safety aspect).

I also think it's funny the Italian colours on a Japanese rider. Yamaha are trying to appeal raise eyebrows in a certain market i.e. the continent with the strictest emission standards in a bid to say "Look at us. We are the future"

Clutch? Where's the New Yamaha Blueshift?
Sss suspension, a clutch, and keeping the peace with the neighbors would be great. And no black wheels!

That would be perfect for my property. Wonder when/if it will ever be available in the US.

Someone help my wrap my small brain around this.

With no revving, essentially it would be the throttle controlling the amount of torque that your clutch can produce?

I just imagine having the throttle slightly more cracked than you anticipate, dumping the clutch and instant loopout.

I'm sure engineer's much smarter than me have already worked this out. Even a fake tach that would simulate RPM's would help.

What a cool machine, bring on the MX model. What about map changes by left foot?

Yamaha has not said if there’s any plans to offer an electric trials bike to the general public, but there are a couple other manufacturers that will soon be offering their own models fully equipped with a clutch and even a transmission.

That did help, thanks!

Most of us are still clinging to the clutch as an outmoded way of delivering the power. We MX racers use the clutch to isolate the engine from the rear wheel because we need the power to be delivered smoothly or at a more effective rev range.
The thing is, electric motors produce ALL of their torque at any RPM, thus eliminating the necessity for a clutch lever as a means to meter out the power or to increase revs. All you'd have to do is twist the throttle and learn to control the power in that manner.

Braaapin' aint easy.

Black wheels are boring now... they were sick 20 years ago. blah today.

I cant do any of that fancy trials stuff he was doing, but that still looks like a blast almost like a big DH MTB rig!

Electric torque is not constant, and it is highest at 0 RPM.

You need a clutch to control load on suspension for splatters
