Messenger bikes are the ones that bike messengers use, normally nighthawks, they are standard bikes mostly, but... still some of them use CBRs...We don't classify them in the "standard" category, hell, most people dun really care what they are, most of them and old and dirty and beat up, and are either Hondas or Suzukis. Our country doesn't really care much for bike class, there's only scooters, sportbikes and cruisers. Respectively, Young kids learning to ride on scooters or small bikes, then young adults driving sportbikes like there's no tomorrow, and the usual 40 year olds driving around in Honda Shadows, and such...
There isn't many bikes around here, everyone drives a Suzuki, either a Hayabusa, or one of it's underlings, but still, there are plenty other bikes around here...
Though Scooters took over 3 years ago, from Vento to Kymco, 125s to 650s, Scooters are motorcycles, maybe not classified as big bikes, but...it's the same, it's a two wheel vehicle driven by an engine... so it's a bike, its' just smaller... btw, scooters in my country, 180cc scooters, can beat a Hayabusa in the 1/8th of mile, fastest scooter around here is running low 7s... I got a 250... hopefully i'll sell it and get myself a ZX-10R this summer...it's bout that time...
