[QUOTE=vickytulla;4377580]The 250cc engine belongs to this Bike :
and these are the specs (not to mention it has more torque the Kawasaki KLX)
Motorcycle model: LF250 (dual sports)

Exhaust Index: CO≤3.8%；HC≤800ppm

Brake Performance: ≤7m/30km/h
It says here that the max speed is just above 100km/h, which I guess is not to be confused with the engine's actual performance. This bike weighs 148kg (on empty tank) and then I suppose the gearratio's/sprockets are set to allow for alooot of acelleration, since it's a dirt/terrain bike it needs that, am I right?
When installing this on street/roadbikes such as most of the one's in Pak, one could adjust the gearratio's to allow for comfortable 140km/h+ speeds? How does it work?
The average mechanic doesn't know about gearratio's he's only bothered with fixing bikes which won't run ......so confusing...
