Ok, thank you Cynic for your replies. It is a 60 plate and is there anything I can do in the future to give it that extra??

Erm, OK then.... So adding a 250 barrel/ piston/ computer bits (ECU) would not be a option then. I have a full bike licence and am looking at adding a bit of extra oomph in the future.... Better start saving for something bigger then.

Probably been covered before, if so sorry. Can someone let me know the main differences between the 125 and 250 apart from larger barrel/ piston. Many thanks
