My IIA 1-Ton will do about 65 flat out and absolutely screaming - no fun at all on 900x16s and with such low gearing. Been a long time since I had anything like that kind of speed out of it. Its normal cruise is about 40-45 depending how flush I am feeling for petrol money (it does only get 12 mpg)
My 110 Puma is of course limited to 82, which it has done on the continent, again not very pleasant, the handling is crap at those kind of speeds, its noisy and very thirsty. I usually cruise it at about 60 which seems nicer. In any event, its limited to 50 on single carriageway, 60 on a dual and 70 motorway anyway so no need to rush.
