I owned two 1100 Yamaha V's and they were as good as that engine configuration can be. Smooth, decent low end torque, no heat issues (probably due to low compression; I don't think it even required more than 87 octane).
The air-cooled twin market is mostly veteran riders; seems as though most under 50 are going for adventure, dual-purpose bikes, or more sophisticated / efficient touring setups. Seems strange to me that they would invest this much into a market that is at the end of their bike buying years, not in the middle or beginning.
I want to ride this bike and see what it is all about. The wide tank may bother me, plus it just feels bulky. Maybe that is different once underway. I need to feel comfortable throwing a bike around in an evasive maneuver in order relax while out riding.
As for heat, I live and ride in upstate NY; we only get a couple dozen days above 85 F most years anyway, and I ride on state and county highways with little traffic so engine heat in hot temps and stop and go traffic are not really factors for me.
