Here's my two penn'orth! If you're a big bloke you might find the A7 a bit short on power. I'm over 18 stone and my A10 is much more fun to ride than the A7 because it is more willing. The A7 needs buzzing a bit with my weight on it. If performance isn't an issue I'd base my judgement on potential reliability. What you (probably) don't want is lots of maintenance work to start with. Find out as much as you can about both bikes and, provided you're not paying over the odds, go for the one which you expect to be reliable. I think the priority would be the reliability of the engine rather than cycle parts or electrics as these are usually quite simple and easy to fix. A tidy and sweet sounding engine would be my first priority, confirmed by a proper run where the bike should handle reasonably well and not have any problems which need fixing. Hope that helps.
