...that brings me to the Versys. It is 300 pounds lighter but that is about all that I know other than the brochure. Looking forward to any advice that I can get. Thank you,
...I know enough that four cylinders is smoother than two and as it is, I'm going down from six....
Bill - I came to the Versys 650 ['08] from a Suzuki Bandit 1200S, and in the 11 years since I got my FIRST one which I still have, at 82,4xx miles, (since '11 I HAD an '09, and HAVE a '15 TOO!) I've ridden them OVER 155,000 miles.
BEST handling bike I've ever ridden, and certainly smooth ENOUGH. Rode across Canada and back summer of '17 (8,668 miles in 25 days, camping, on the '15 650LT), been up to Inuvik, Alaska, Dawson City, YT SEVERAL times, and I'm ONLY a few years younger than YOU are.
IF you're really concerned about a top-heavy bike, consider the V300, and PLAN to get the seat modded for comfort - it is like sitting on a 2x4, but the bike is GREAT! It has 39HP, which is ONE HP less than the Triumph Bonneville had back in '62, and weighs the SAME.
