Buy the biggest, fastest, deadliest plastic-covered sportbike/biggest, heaviest cruiser you can obtain credit for. ('cuz them lil' 600cc Supersports an' 1500cc-and-less Cruisers you'll just outgrow in a couple of weeks)
Then, don't worry about gear or training before you pick it up - just hop on it and demonstrate your Manly Skilz by pinning the throttle (that twisty-thingie on the RIGHT handlebar) as far as it will go.
Jam it in gear (that funny clickie-pedal next to the LEFT footpeg: tap it DOWN), and dump the clutch (that silvery lever-thingie on the LEFT handle bar. your other Left....).
Hopefully, you're outside already, and pointed at traffic or a nice, solid cinder-block wall.
Do that, and you'll certainly leave an Impression that won't soon be forgotten.
Yeah: Nike makes expensive shoes, Levi's are among the priciest jeans, Toyota's Lexus division makes really spendy "Luxury Cars", and Lucas Electric makes vacuum-cleaners that don't Suck.............
You're Welcome.
