A ridden motorized vehicle such as a motorized scooter, motorcycle, ATV, tricycle, snowmobile, or lawn tractor, having a driven rear wheel may be equipped with an enclosed chain or belt drive enclosure having a first end and a second end and an inner enclosure and an outer enclosure, such that the inner enclosure has the rear suspension member and the rear wheel mounted at the second end, and concentrically pivots at the first end on the motor assembly output shaft of a motor assembly fastened to or comprising part of the main vehicle frame, and the outer enclosure pivoted on another bearing co-linear with the motor assembly output shaft, but mounted on a removable section of, or attachment to, said frame.

A motorcycle frame includes hollow left and right frame members that define a fuel-containing volume. Left-center, right-center, left-rear, and right-rear engine supports each depend from a corresponding left and right frame member. Each engine support includes a first portion that is coupled to the frame member and a second portion that is coupled to the engine. Each engine support also includes a stress riser defined between the first and second portions. The stress riser is configured to cause the first and second portions to separate from one another in response to application of sufficient force to the engine or second portion. By causing the first and second portions of the engine mount to separate in a predetermined way, the frame members and the fuel-containing volume are left intact.
