I agree on not wasting money on tweeks for a new 125. Save your cash, keep the bike tidy and standard, do your A1 test, in two years time get a nice bigger bike. I spent 300 quid on my exhaust for my CBR125 and another 40 on a air filter. To be honest the exhaust and air filter added hardly any power, sounded nicer but performance wise, its hardly noticable. I dont see the point of tuning 125s for the road. Most vehicles on the road will go faster than a 125 any way. The best way to make your 125 go faster, is to take extra training, road positioning etc.
