Motorcycles and scooters are a great way to avoid traffic, saving time, money and unnecessary stress. And they generally produce far lower greenhouse gases than other motorised vehicles. Commuter motorcycling accounts for two-thirds of powered two wheeler trips and represents one of the cleanest forms of motorised transport for trips where walking, cycling and public transport are not viable. Motorcycles spend less time in traffic jams, whereas cars spend time with engines idling and air-conditioning running.
