Power to weight ratio would be the issue. If it was a 600 ACE (60 HP) then it would be a smaller, lighter platform altogether. If the RS was to stay full-sized, then the 900 ACE (90 HP) would be more logical. I just don't know about the whole less expensive angle here. I don't see that as the primary objection from potential buyers. Look at what is sold now and what the owners are doing to them, what kind of rig are they creating? Look at what people are doing to their F3s right now - that should be our best indicator. This is what steered the RT from what people were doing to their GS/RS models right from the start.
I keep coming back to the question of who they are trying to sell units to - the current group of us Spyder owners, or that great big aging demographic that is on two wheels right now. That is the nut they so desperately want to crack open. We have already bought into the 3-wheel thing, so we are not the main target. How do they make a Spyder "cool" and "desirable" to the masses? How do you make it horny and lusty, something that people want worse than anything else? That is the multi-million dollar question here.......thus, with an intro at Sturgis it has to be something that will appeal to THAT demographic.
