Wow, Bob, that Vulcan looks very comfortable! I can tell you're a very experienced rider with lots of experience with bikes. The seat height appears fairly low and slightly forward controls means less knee bend, also great for comfort. No doubt, way more comfortable than the Ninja 1000 I had previously, lol.
I've also had many bikes of various kinds and since adding the AK550, I thought I would never again have a chain and manual transmission. That preference didn't hold up ultimately since I missed my sporting days and added a Yamaha Tracer 9GT+. Like you, I'll put up with the chain maintenance. As far as the manual transmission goes, this bike has a great quick shifter both up and down. It's actually fun and the performance is pretty incredible. At any rate, I plan on keeping the AK simply because it's a great grocery getter and perfect for shorter rides and errands. The new Tracer is, for me, a thrilling ride and one I can go unlimited distances if desired.
