ADVENTURE & WILDLIFE ridership saw a resurgence. Sales of motor- cycles and scooters declined 43.2% in 2009, and continued to decrease in the first quarter of 2010, with scooter sales doing worst, down 13.3% compared to a 4.6% drop for all two-wheelers. Other types of small motorcycles include the monkey bike, Welbike, and minibike. Off-Road There are various types of off-road motorcycles, also known as dirt bikes, specially designed for off-road events. The term off-road refers to driving surfaces that are not conventionally paved. These are rough surfaces, often created naturally, such as sand, gravel, a river, mud or snow. These types of terrain can sometimes only be travelled on with vehicles designed for off-road driving (such as SUVs, ATVs, snowmobiles and mountain bikes) or vehicles that have off-road equipment. Compared to road-going motorcycles, off-road machines are simpler and lighter, having long suspension travel, high ground clearance, and rugged construction with little bodywork and no fairings for less damage in spills. Wheels (usually 21” front, 18” rear) have knobby tires, often clamped to the rim with a rim lock. There are specialized motorcycles for a variety of off-road motorcycle sports: • Motocross — Such bikes are raced on short, closed off-road tracks with a variety of Vol 4 | Issue 2 |Mar - Apr 2019 obstacles. The motorcycles have a small fuel tank for lightness and compactness. Long-travel suspension allows riders to take jumps at high speed. Motocross engines are usually single- cylinder two-stroke or four-stroke units, which vary in size from 50cc up to about 650cc. Motocross sidecar outfits have bigger engines, usually four-stroke and often twin-cylinder. Motocross bikes are also used in freestyle moto- cross. • Enduro — A modified and road-legal moto- cross bike, having the addition of a horn, lights, effective silencing and a number plate. Enduro riders compete over a longer course (which may include roads); and an enduro event may last between one day and six days (such as the International Six Days Enduro). Some enduro events (known as “multi-lappers”) are held on rather shorter circuits, not unlike scramble tracks. “Multilappers” are especially popular with novice riders. • Rally raid, or “rallies” — A special type of enduro bike with a significantly larger fuel tank for very long distance racing, typically through deserts (e.g. Paris-Dakar rally). Engine capacities tend to be larger, usually between 450 cc and 750 cc. • Trail — A trail bike is a dual-purpose bike, made for on-road and recreational off-road riding. A trail bike may resemble an enduro bike, but since a trail bike is not intended to be used for competition, 77
