Old article, been on here a couple of times... still, love this part the best about the Big Dog:
If only it were a bit more comfortable to ride over 50 miles, or above 50 mph...
...assess city manners and slow-speed handling behavior. This, in the case of the Big Dog, can be summed up in one word: DON'T! The K9 doesn't flop or fall over at slow speeds like you might expect, though it takes a lot of muscle to maneuver such a long, tall, heavy bike. You're always aware of that 13-inch-wide rear tire, too, with its Weeble Wobble tendency to right itself mid-corner--despite the balancing effect of Big Dog's proprietary "Balanced Drive System," which relocates final drive to the right side of the bike. Heat management is an issue, too. Temperatures in the mid-90s were enough to momentarily kick the K9 into self-preserving limp mode at stoplights.
Like dog years, it seems 300 Big Dog miles are roughly equivalent to 2100 human miles, and we were feeling every last one of them. All that airspace between the K9's low seat, high bars and forward controls make it impossible to brace your body, and with a scant 3 inches travel from the hidden, Softail-style rear suspension, every expansion joint sends a jolt straight up your spine. Then there are the vibes--any acceleration shakes your feet off the pegs, giving your hip adductors a workout keeping your feet in place. You'll soon curse the K9's 130-mile cruising range--even 50 miles at highway speeds is hard to bear.
