Doesn't the G5 have a kick start and the C5 doe not? If that's so, then for me, I'd choose the G5. I love having a kick start-even if a bike has a 100% reliable electric start system.
Vince, I didn't realize you had any fuel injected models in stock right now. I have yet to see one- let alone ride one. But I'm back to work next Tuesday after another temp (one month) layoff, and will still have Sundays and Mondays off.
Take care, Jon
