context_page_description: An underbone is a type of motorcycle that uses structural tube framing with an overlay of plastic or non-structural body panels and contrasts with monocoque or unibody designs where pressed steel serves both as the vehicle's structure and bodywork.
  Outside Asia, the term underbone is commonly misunderstood to refer to any lightweight motorcycle that uses the construction type, known colloquially as step-throughs, mopeds or scooters.
  An underbone motorcycle may share its fuel tank position and tube framing, along with fitted bodywork and splash guards with a scooter while the wheel dimensions, engine layouts, and power transmission are similar with conventional motorcycles.
  Unlike motor scooters, underbones are mostly popular in Asia, particularly in Southeast Asia, Middle East, Taiwan, China and North Korea, in Latin America, as well as in some parts of Eastern Europe, Greece and Russia.
