Hi Declan, Wendy is currently carrying the weight of a small person in luggage, maybe 50 kilo🤔. She says she cant notice any difference. So im guessing a small pillion should be fine. We dont go over a 100 kph either, so, hitting bigger speeds with 2 up may be difficult too. You have a fairly wide car tyre on the road up back, so stabilty seems good. Summing up, if the 600 is as far as the budget stretches, and you both are average size, I reckon its do-able. Hope this helps, ride safe👍
