A regular motorcycle has a ‘sequential’ manual transmission, meaning you can only shift up or down one gear at a time. It is also designed to spin one way only. Adding reverse would require the crankshaft to spin backwards, or a much larger, heavier, expensive transmission. So it is easiest to dismount and push the bike backwards.
