The Fury isn't hiding anything. The max horsepower is at 4300 RPM and the max torque is at 3100. This is for a stock Fury and with some mods some things change, but not drastically. The max power for the extreme mods done on the Motorcycle USA Project Bike (2010 Honda Fury Project Bike Preview - Honda Cruiser Project Bike - Motorcycle USA
) include substantial engine mods and the max power is still at 5100.
After you hit the max power RPMs the power tapers off and gives you LESS power. You could try to bypass the rev limiter but if you succeeded you would actually have less power by reving higher then finding the proper shift points. Also you risk blowing the motor up.
Okay so you mod the engine put max HP and TQ output 150 spins below where the rev limiter cuts it out right? 5100 you get to max then half a second later you fall on your face when you hit the spin killer. Now ask around and look at other performance charts out there for any type of competitive machine and see if you dont run at least 1000 rips past the hump. You cant enjoy any of that seat of the pants performance without extending it a little bit oh and don't forget we also got a speed limiter to deal with too. again like I said not worried about beating the speed killer, but when i kick her in the arse from the light or in a pack, i wanna be able to walk a little taller in the first 3 just like anybody with a performance machine does. Take a look at any dyno chart for just about anything and see if the redline and the top of the curve are the same.....they aren't. This ain't the first scoot with these "safety" additions for example most of the cows out there have speed and rev limiters but do a little research and see what you can do with 2 pieces of wire about an inch long (jumpers) and all the cows have ECU's too. Its not so much reprogramming the CMOS as it is figuring out how to fool it. Do some research its out there for almost all the other brands, so its hard for me to believe the great winged one from across the pond has come up with something so different from the rest of the world that it cant be done...think about it. Go buy a power commander that also controls the ignition and you will see a little tab up there that say "rev xtend" so its a click of the mouse, but if you look at those for these scoots born under the rising sun they have no ignition control, only fuel management.
