Hello all,, To set the record straight,the 2007 to 2009 CBR 125's have Fuel Injection. So yes your bike is fast for a 125 it has been modded(big bore kit) and the carb has been modified too along with the CDI unit. With E.F.I. the 07 and up CBR 125's are harder(at this point) to modify because the aftermarket venders haven't developed products ,,yet. So a STOCK 125 R will reach about 140 KM/HR or about 80 MPH. The CBR 150 R 's are made for the Asian market and have a 4 valve head (125 R has a 2 valve head). So the 150 R is rated at about 18 HP(stock) and the 125 R is rated at about 13.5 HP (stock) L.Potter

 

119 km/t on highway? that wasnt much, that must have been in headwind?

i had mine do 135 kmt with a bit tailwind, if the road is long enogh it do 140 kmt and thats it you gain a lot if you shrink on the tank, sorry my bad english

i miss more torque on it, therefor i want a cylinderkit that will give 4-5 HK, which is fine for me, and then a other sprocket 1 tooth

 

You can go with just a Cylinder kit and get 160cc. Best bet would be Complete Cylinder and Head with Bigger Valves and Camshaft. All depends on what you need and want.

 

hello all... new owner of a repsol 2006 CBR125.. and i was wondering,, which exhaust sytem is best... Remus or GPR? because the resrictor is in the exhaust but i can still his 84 mph... want to hit a ton with different sproket, uprated carb (bigger jets)... anymore suggestions?

 

Buy a 600 lol

 

"Buy a Ferrari lol :-)"

 

Would they do 110km for an hour or so fine? Or would I be drestroying my baby babyblade? =P

 

i have one here in canada, i only bought it because of insurance and im 19 so i gotta build up a good rep before moving up to the higher cc bikes.

I have to say its a great bike for the city, i live in brampton and its a rural area so traffic is around 80km/h and my bike is pretty quick to catch speeds and keep up with traffic, but i dont recommend highways cause the bike is very light and gets tossed around with heavy headwinds
