so they can sell you a whole new motor when it breaks, and then chastise you for not following their maintanence schedule 
the reason is that to have to motor non-interference, the fuly open valve musn't come into contact with the piston at TDC (obviously) and this takes a little more creative effort when designing the piston and head.. effort they cbf going to.... the tradeoff for non-interference is chamber/piston shape, and compression ratio. it's easier to have higher CR with interference..
anyhoo,
