Because the spark plug must fire when the piston is at top dead centre of a compression stroke. If the plug fires when the piston is at any other position then you get backfiring etc and no start.
The correct firing order ensures the plugs fire at the right time.

What do you do if your motorbike does not start?
It depends on what is wrong - if the starter-motor does not operate it is probably a flat battery (charge it), starter relay (replace it) or starter motor (replace it) - always check for corrosion / bad earths. If the starter-motor is operating but the engine isn't firing it could be any number of things - but for a motor to run it must have: compression, fuel & ignition. The easy answer if your bike does not start is to get in touch with a recovery organisation or motorcycle dealer (such as ourselves: http://www.aprilia-merseyside.com )
