What could "gear rush" mean wrt motorcycle riding?

Hello, riders. I’m doing a translation for a Japanese motorcycle company, and the person speaking in the video uses the term “gear rush” (gia no rasshu). The new bike has TBW control that prevents this and unwanted bursts of acceleration (dontsuki). Google tells me that there are only 17 cites for the Japanese phrase he uses (and 23 more without the “no”), and none of them really fit–so he’s pretty much using his own lingo.

I don’t ride, so I was helping you could understand the phenomenon he’s talking about, and based on that I would choose an appropriate phrase.

Thank you!

Does the bike have an automatic transmission? If the TBW prevents unwanted acceleration, perhaps it also, working with the transmission, keeps it from flying through the gears too quickly, leaving you in too high of a gear for the speed you’re at.

Thanks! I think that’s a good suggestion, but it appears that this bike is manual, not auto. What could it mean in an auto context?

I can think of a number of new technologies that advancements in electronics packages have brought to motorcycle transmissions, but they’re all in the “enables” category rather than “prevents”. And throttle by wire is only loosely related to those functions.

The big new feature most sport bike gearboxes are getting now is a quickshifter. That enables the rider to shift up and down without using the clutch but either briefly cutting power (for upshifts) or blipping the throttle (on downshifts).

Any chance you can relate the model of the bike? Maybe in PM if you don’t want to say publicly?

Thanks! PMed you.

For those dying to know, based on the info shared privately, I’m going with quickshifter.
