Hello everyone been a while since I posted here and sorry if this is the wrong place to post this well my dad is a mechanic knows almost all the how to's on bikes and recently we had the idea of tuning the engine to get increased peformance and speed on my CBR 125 Repsol and he says he knows how but doesnt know thecorrect bits to use for the engine so he has told me to ask on forums and where better than a dedicated CBR Forum so basically what parts like valves e.t.c at the moment everything is stock to my knowledge except the exhaust which came with the bike when I brought it (it's a 2nd hand bike) We replaced the old Carb with a new one correct model for the bike so its like a stock Carb just a good condition and so what parts should I get for my bike to increase top speed from 120kph to lets say around 190-200kph my dad knows hot to install parts we just need the parts if you also know a website to order from would be nice but if not the name and details of parts would be great, thank you.

 

You want a 125 to do 190-200 KPH
WHAAAT ?
D'you have some kind of death wish or something ?
You'd need to completely modify the engine, which would probably cost you more than the bike did, to get that sort of performance increase. I suggest you look up the post on mods for the 125's in this section...................

Secondly, your brakes wouldn't be up to the job of stopping you securely from that speed.
The tyres aren't rated for that kind of speed, so you'll need special tyres too.

Just my 2c worth

 

Well are there any like tuner up kits for the CBR 125?
