Jim Cummings Ideally you should never shift at peak HP if you're looking for maximum performance. Forward thrust is essentially controlled by wheel torque. Any time you upshift, you increase the gearing disadvantage your engine has. The goal is to shift at the point where wheel torque in the current gear starts to drop below what it would be at the same speed in the next gear. This is usually somewhere after peak horsepower. You can often find charts that demonstrate this. For example, on the FZ-09 featured in this video, peak horsepower is at 10,000 RPM while redline is at 11,250. The optimal shift points depend on the gear ratios. When shifting from first to second, it's actually optimal to shift at redline and the optimal shift RPM slowly works its way down to about 10,800 RPM from fifth to sixth gear. On many bikes the best shift points should be somewhere around redline just like this, but it can be evaluated on a bike by bike basis.

I'm way late here, but there's no way in hell that stock gears on fz09 are good for 170 mph, I've had mine at the Rev limiter in 6th gear and first of all it's terrifying, and second your doing right around 145, my bike is flashed and piped and there's absolutely no way 170 is happening with stock gears.

@@wymonwatson1309 Your bike can't have stock gearing then because I can hit that speed in 5th

@something1random23 You make a vid doing 170 on an mt/fz09 and I want to see GPS speed, I promise you your not doing 170, my bike has stock gearing, I've been thinking about gearing it up, but it's already pretty scary doing 150 on a naked bike.

The limiter sneaks up on him Everytime. He needs an automatic or a bright shift light with a electric shocker in the seat to help condition him.

tubesvrider when you enhance the revolution speed increases. The speedo reads the same but your gears are longer now so the too speed in each gear changes. With going one up in the front I brings the bikes calibration closer to 100% witch also changes the speedo. 1st takes off so smooth now and 2nd rides out longer so wheelies you have a lot more room to work with in your gears.

+MCON89 - But I understood that you got a higher reading ( and higher topspeed-reading) in your speedo? And if the speedsensor is located at the outgoing shaft, you shoulden't get any different reading, the actual speed being higher, ofcourse, but rpm vs speed shown in speedo should be unchanged

tubesvrider correct

Dude that's retarded lol. Unless it's a pure stuntbike that's way too high

I hope you like tarmac sandwhiches

Every OEM except Harley Davidson purposely programs the speedo to read about 5-8% fast. Reason? Litigation issues with potential speed related accidents. You'll have to ECU flash to correct it, or get a down-stream calibrator plugged into the speed sensor wires.

Ya i need that info too bro, hope u can help out!

Why not both! 😂

I just swapped mine for a 17 and it still power wheelies in first. Second as well if you pull back on the bars.

i got the ecu flashed for a better mapping and for the slip on exhaust. it also deletes the stock speed limiter

thank you. I also just found 17 tooth sprocket for an R1 that is A 525, which is the FZ-09 OEM chain size. no conversions necessary. www.sportbiketrackgear.com/vortex-yamaha-yzf-r1-15-16-525-steel-front-sprocket/

Im not up to speed on flashing. But, I will be doing a slip-on as well. Where would a look to get my ecu flashed?

I just looked online and research a lot of companies that flash and picked the one I thought was best

yes its not recommended tho.

+pennsylvania woods yes

had a hard time finding reviews and general Info on this bike from someone who was not right in the city/ urban riding

This thing power wheelies in 3rd gear and you think it's geared too tall...?

I'm crusing close to 80 more often than I thought and rpms don't need to be that high (6k if i recall) and yeah 1st gear feels like a big rig granny gear to me

probably dont fit
