Can you ride an Aprilia RS125 at age 16 if you restrict it to 50 then use it fully at 17?

Take in mind there is no quick fix to downsize an engine.

Firstly you will need to buy yourself a rs125 ''top end kit,'' (piston, cylander, pin and circlips) an aprillia top end kit will cost about £400, cheaper paterned parts ie Mettaka are just as good and quite cheap (aprox £150) but will void your warrenty.

secondly you will have to get a capable person to fit the kit, (also remember all two stoke engines rely on crankcase presure to power the engine if your running a 34m carb (standard rs125) the bike will scream as soon as you fire up, your crank case will blow or the piston will seize within the first few miles. alas! you need another capable person to rejet your carb! :-)

Thirdly you need to book an apointment with the DSA test centre, for around £100 + Labor a mechanic will judge the bore of you bike.

All in all this is what it will cost you

£150-£400 Topend Kit

£200-£300 Fitting and rejeting

£100-£200 Bore Assesment

Total

£450-£900 - Take my advice, Just wait till ya 17

:-)

PS: you can use all roads on a CBT apart from motorways
