You might need a Left- handed screw driver to fit the Power bands too..

That's normally only for 'left hand drive' models afaik, if it's a UK 'right hand drive' model then I think you are fine without one

f**king lol at this thread, I don't think he's coming back now anyway.

However if you do, you're gonna need a litre of elbow grease to fit that power band.

Good old elbow grease.

My mate used to work at the Honda specialists, he said if you're trying to fit a powerband, its crucial that you use elbow grease otherwise once installed, the power band will snap under the immense weight of the average cbr/f 125 rider.

be carefull fitting those powerbands! one flew off and broke my nose once, a nice tip is to use vaseline to lube up the nipples before bringing it home.

Try converting it to diesel, powerbands are still better though, I put gold powerbands on my skyjet and gives such a smooth power and responsiveness, not too much power but still noticeably more, topped out at about 80/85

Would it not be easier to upgrade to a bigger bike.

Give either collywog or russ/ squirell a message mate.

That tricolour one your getting me to test is the best one ever russ!

My mito now does 145mph!! and it goes a month on 5 quids worth of fuel. So much quicker than r1 turbo's too

IIRC the CBF, ulike the CBR, has a belt-driven triple overhead-cam configuration so you make sure you get the INFINITY powerband (actually called a torque-band). After this reinforced kryptonite band is installed, although your peak power will remain the same, you will within reason be able to gain unlimited lb/ft of torque, hense 'infinity'. So for example you will still have say 12/13hp but 470lb/ft of torque and this will deffinately give your CBF a lot more grunt. In theory you would be able to pull a small plow.

Hope this helps,let us know how you get on with finding the right band

You seen the price of them though? lol

Be sure to go easy the first time you go for a ride with new power bands if you're not used to them. I made the mistake of giving my cbr too much throttle pulling away from the lights, front wheel came up over my head and ended up flipping it

I hate seeing poor advice given out on here. If you are going to try fitting powerbands then i would recommend getting some practise in on a sports 600 first, then it won't be so much of a leap for you. Yes it's all very funny guys but it won't be if he kills himself

i rang halfords and asked for said powerbands, but they just laughed for a few seconds and hung up, do they not realise i can handle the immense power of them?

ive had gold powerbands fitted to my race track bike before, you have to be careful not to exceed 88mph with them fitted though, otherwise the regulator outputs more than 1.21 jigawatts and youll find yourself back in 1955.

trust me on this.

I painted mine with tartan paint so I have all the best colours needed to crack 100mph

I'm experimenting with Global Hypercolour powerbands that change colour depending on temperature. That way I can't overrev the engine until it's at full temperature. Once I'm up to temp, the powerband changes from blue (rev limited to 6k) to red (unlimited revs). This should help prevent seizures.

Im not sure if russ stocks them, but i know all of the race spec aprilias use Titanium/Vanadium alloy powerbands (2 per cylinder). They dont have the most power increase (around 90% of the rainbow ones), however they do increase the torque no end, you can easily to a small elephant, and you can even wheelie in 6th. As stated above, elbow grease is mandatory, as is the use of 156RON petrol at all times, otherwise the powerband will not be fully lubricated, causing it to snap and lock up the front wheel, meaning you will go head over heels.
