Computing gear ratio max speed?

[Wallace.28]

What's the fastest way you compute the max speed for each gear ratio? I got a 2021 GSX-R750 and everything is stock. If anyone can point me to online calculators or just any advice, I'd appreciate it!

Easy way, get your gear ratios, final drive, and tire size, then plug them into an online calculator like bikemath buh, if you want to DIY, max speed = (RPM × tire circumference) ÷ (gear ratio × final drive × 60), simpler to see what each gear can do

@Adobefan spot on with the formula, with your 2021 GSX-R750, you'll probably see around 80+ mph in 1st and close to 170 in 6th, give or take, do let us know if you're thinking of changing sprockets then it gets even more fun, cheers

Hey! Fastest way by far is an online gear calculator. Just plug in your GSX-R750's redline, gear ratios (from your manual!), and tire size.
Blocklayer's Gearing Analyzer is super popular for this. You'll see those speeds per gear instantly!
