It's still 50cc
I'll probably just keep it for the 10 months or so, then sell it for a car. Doub't I'd move up to something bigger.
Imagen having a 1000cc, 70mph in first gear..
sorry for old quote, but you'll never be able to get the RS go 70mph orginal
New carbourettor, new cylinder (which dosen't make it a 50cc anymore), new exaust etc.
and thats bloody expensive + it's illegal and you may loose your lisence, get a big ticket and loose the license plate
I have a Yamaha TZR, the biggest (and in my opinon the best racing-bike in the 50cc class) I had a new exaust on it and it went around 90km/h (think that's about 55mph), but I changed to the normal exaust with no restricons in it and it now goes about 70kmh
it's brilliant
