dead easy - board on side - on a motor bike - just grab two 'occy' straps - one for the front & one for the back ... attach the front one to
the front mirror or similar spot on the handle bar - the back one usually around the back blinker or similar spot

I've used them for surfboards as well on motor bikes in Bali & Thailand...

(much better than as a backpack as u get too much wind drag)

B warned, that if you have any rack on the side of any vehicle , including motor cycles . they cannot protrude more than 150mm .they can be defected as a dangerous protrusion

My method . Probably not recommended in Aus/NZ for reason mentioned above.

Cheers all, thanks for the feedback..
Looks like I'm just gonna go with some racks and see how they go
