Hence Chelsea tractors, Supermoto motorbikes, high heels, goatee beards et al.

One of these doesn't belong.

What kind of motorcycle do you want around town?

Light weight and wide bars for manoeuvrability
Upright riding position for good vision and to keep the weight off your wrists as slow speeds.
About 40hp from a simple single cylinder motor, for lower weight and better fuel consumption than a multi-cylinder motor.
Only needs about 2 gallon tank, keeps weight and width down while providing all-day range for urban use.
Plenty of grip and good brakes from true road bike equipment, but with enough suspension travel to soak up our unmaintained roads.
Motocross plastic is crash proof, stops a trivial fender bender from turning into an insurance claim.

If you were designing the perfect city motorcycle, you might not end up with one of the current production super motos, but you might be quite close.

In fact, as bikesnobnyc keeps pointing out, for similar reasons we don't need no stinking Dutch bikes when a rigid MTB with Schwalbe SuperMoto Big Apple tyres will do the job better for half the price.
