Yeah, but then you don't have an R125 do you? Think about. It aint the same bike after all that.
i was researching for you guys and my self as im sticking with this till im 24 then doing full bike test then getting on a restricted r6 cheaper and i like modding things and tunning them moneys money at the end of the day aslong as i got a good income i will spend it on parts i can sell them later on if dont want them no more or changing them.For how much it will cost mate, you're best doing your test and getting a bigger bike. Not gonna make any drastic difference. Theres only so much a cyclinder on a 125 engine can do
I've read up on it, and it's possible to have as much as 35+ hp from the R125 engine if it's completely modified. (210cc kit, bigger injector, PCV, air filter, camshaft, larger head etc.)
That's about what a 400cc puts out (for example the DRZ)
So, you can get a bit out if it, but, you'll never be the fastest one on the road
However, a 35hp R125 would beat many cars
