my scooter thinks its a superbike

had my scooter for nearly a fortnight now ,and done quite a few miles ,been everywhere ,got lost a good few times
I bought the scooter off a mechanic who's rebuilt it and most parts are new ,its got a leo vince racing exhaust and god knows what else he has done to it, but it is rapid ,and I mean rapid .
it's got 50mph on the clock ,it reaches that at 3/4 revs on a straight and just keeps going ,I can burn cars off who want to race .
only thing is I don't think the brakes have been upgraded to cope with the speed as it takes a good bit of distance to stop ,it's not to much of a prob at the moment, just need to leave more room between other cars and upgrade next payday .

anyone else getting speed like this from a 50 ? and what could he have done to it to make it so fast ?
not got a clue about engines and the like, so just curious .

 

possibly a 70 kit, maybe tuned as well, larger carb than std and racing variator...the list is endless. A decent 70 without tune should nudge 70mph if you're lucky

 

would it still pass an m.o.t if it was a 70 ? as it only went through on the 6th of this month .
as I say I don't know much about them really ,apart from sitting on and steering lol .

 

nice! My speedfight 100 takes about 3 weeks to get to 50! thats with a 19mm stage 6 carb on as well! fml

 

55-57 for a 50

 

it's a Peugeot jetforce 50 c-tech on a 55 plate ,
sorry don't know what ac /lc is , so how will I find out .
im wanting to learn as much as poss ,with a view to upgrading parts myself .

 

all of my 50's have done 50 pretty much standard
