Clutch? Helps in down shifting.
And any rare times that you want to just coast.
This is my one issue with the "has a transmission so it will be familiar to ICE riders" marketing bullet point. Yes, it's possible to ride it and shift it just like an ICE, but it will be quirky, spin to redline a lot, and act all sorts of crunchy. It does tie in to that muscle memory quite a bit, but you need to know a few differences to really be happy with it:
- Don't use clutch at stop or to launch. It's unnecessary and detrimental.
- Don't use clutch to upshift unless/until you learn to power shift it, then never again.
- You can learn to not use it on downshifts, but it's not much of an issue either way.
- Don't upshift prematurely, target 5000RPM. Higher RPMs are often more efficient with more torque.
- Roll back 1-2 inches at a stop to eliminate drivetrain clunk completely.
- (Early on I sometimes used the clutch when parking or maneuvering in garage to prevent accidental throttle input. I dropped the bike once by not realizing I was twisting the throttle while parking until I got more used to the live throttle.)
