Motorcycles come in all varieties. Scramblers and trackers have become quite popular of late with bikers looking for a rugged look and feel to the motorcycles they ride. Having knobbly tires, comprehensive suspension systems, high exhaust pipes, and flat-track or motocross bars, scramblers usually come equipped with dual shocks, engines with single or twin-cylinders, and minimalistic design features. Trackers, on the other hand, take inspiration from actual flat-track racers and feature wide handlebars, chunky tires on tall wheels, solo seats, and a small tank. These motorcycles are usually driven in the dirt and in off-road terrains. A great delight for customizers, there are many builds of the scrambler and tracker type available in the market that has been completed by some of the most reputable custom-houses in the industry.
