hummmm......was i think he can drictly go for 600cc...ager he practice not run fast on very first weak....
i drove zx64...for very first time....and i did around 25km on very first day....but no speeding over 70km/h and not above 3rd gear......
just learned stop and go and shifting gears.....
s ports bike is more easy to handle then those 125cc bike...i dont know why....but i feel more easy with sports bike then those road bikes
