I disagree with this. I have shift lights on the dash of my ZX10r and when I am launching her in anger, once I’m out of 1st gear slip it’s almost literally shift, shift, shift and yeah despite it happening in mere seconds - we’re talking 100mph plus in the time it takes a Rap to get to 60 I still find the shift light usable.
Ditto if I’m exiting a turn on steady throttle, I can use that to keep my perceived need to add throttle in check. No, I’m not staring at it, but, I’m peripherally seeing the tach indicator and know when to upshift based on that indicator.
Now, I’m not sure how much I’d like the wheel gauge / shift lights long term, but I don’t think the shift lights worthless or even impractical. They could work for some of us.
YMMV and I am not responsible if you buy one of these and run over some fiat 500 or prius because you’re fascinated by the new tach light bling.
the difference is.....on your tri-cycle you have actual control of the shifting process and can clutch in before bouncing off the rev limiter. The Raptors paddles are unusably slow. You have to pull the paddle to shift at 4k rpm to execute a 6k rpm shift. So even with those shift lights being "configurable" if you set them to go red at 4k rpm so you shift on time.....your next up shift will dump you almost at 4k rpm.
maybe it would be different for something like baja mode...helping you to stay in the 4,500 to 5,500 sweet spot.
