thats with your specific bike from the gearingcommander website.....

lol not saying thats full of **** but it is....ill hit it with my radar if i gotta....ill try to find some time and space to hit it with my radar and get a video

With one down two up on a 06 your gearing will only allow you to get to 155. Now if its stock gearing it will be capable of 170 but you'll never get there . Even if it says it your not really goin that fast

No offense but simple physics proves this is BS or your bike and riding skills are better then the Honda Pro's that test these bikes.

The attached links Professional bike test driver got a max speed of 158.3mph on a closed course with stock sprockets.
Your sprocket change has lowered your top speed by about 15%.
You guage could be off anywhere from 17-24% off with the factory error.

In which if you were reading 170mph and your speedo was off the max you would be travelling at an actual speed of 137mph, which sounds alot more correct and the math behind this makes sense, That is unless you have a one-of-a kind RR that defies all manufacturers specs? :D

lol come on guys..def no pro rider here... Ill be the first to admit if im wrong. And still may be but id like to radar test it and know for sure.

Gearing commander says at 170mph with your set-up your at 17,500rpm and at 155mph your at 16,000rpm..... But hey I would believe a video radar proof over anything :D

Don't nee radar to tell you what math can. You have set gear ratios in the transmission. You have a set rear tire size. You have set sprocket teeth. You have a set redline for the motor. Combine all that and you know exactly what the bike is able to do top speed wise. Doesn't matter what GPS, radar or your speedo tell you. An all stock f4i can do 165mph at redline. No way to change that without changing hard parts. If you do sprockets down in the front and/or up in the back the top speed will go down. Same thing with an RR.

what he said and mostly everyone else said. its just wat it is, gears only let you do so much. i had 1 down 2 up on my 06 it would top out at 155 everytime.i had the speedo healer on it and it was calibrated on a dyno wich is more accurate then gps . so read gearingcommander.com and believe wat it says because math is math. done thread closed
