i bought a yamaha yzf r125 . will a bigger engine fit in it ? would it be too much work ? what would be the best engine to put in it (east fit and decent power) ?

thanks 4 any help on the subject

sorry i should?

my first bike was a 1992 cbr600f. cost me 1000 squid and was fast enough to keep up with my mates on 3 year old gixer sixers.

for the money itl cost to buy a new engine and the time and effort itl take. ide just keep the 125 as it is for a run around and buy a 15 year old sports 6. it will be faster than the biggest engine you could fit in a 125 would be.

and handing over cash is a bit easier than breaking ur balls changing an engine lol

good luck whatever you decide to do.

i was told maybe a 400cc yz engine could fit but maybe need to change few bit's and few mod to get fit because there is loads of room to fit bigger engine
