Abrégé

A semi-monocoque structure for a vehicle preferring a two wheeler comprising load bearing drive assembly, a shell assembly for providing support for driver and pillion seating matching with the drive away assembly maintaining the continuity of vehicle aesthetic and a pair of sheet metal lockable cowls providing cover and safety for engine and other parts. Drive away portion consist of Front End and Rear End where as Front End is basically of sheet metal construction (1.1, 1.2, 1.3, 1.4) and Rear End is mostly of tubular construction (3.2). A semi-monocoque structure for fitment of two stroke as well as four stroke engine, facilitates use of LPG or CNG tank (3.15) and 2 or 3 stage gas pressure reducer with in the existing shell with minimum insignificant changes.
