Stumbled upon this thread from '20 - time sure does fly! I've ridden a Vulcan S before and loved the feel, though I've always been more of a Suzuki kinda guy. Chain vs. shaft drive, that age-old debate, huh? Both have their merits.
By the way, while you were researching the Vulcan S and Suzuki M50, did you also look into the aftermarket upgrades or enhancements? Found this gem of a site,
don-performance.com, that's got some sweet gear and parts that might interest you, especially if you're thinking of tweaking things a bit. Hope you ended up with a ride that's been treating you well these past few years!
