The speed limit is 70, yes... But when you roll on the throttle of the FJ, you understand why there's nothing else like it on the planet. Move up to 40mph, click up into 3rd and then roll on - You'll be at 70 in an instant and you'll feel the surge of power, but with the perfect security of knowing that the bike is so heavy that both wheels will stay firmly planted... and it's like that in any gear - There's almost no discernible power band.
Going back to the weight - Yes, the FJ is 42 stone (266kg) of bike, but you only feel that when you're trying to push it. You're not going to be flicking it around in the twisties like a 125, but you're not going to be especially struggling with it either. You won't want to reverse it back up a slope, but that's the same with many other bikes. Having unfortunately had to lift mine up off the floor, it's still not that heavy in the grand scheme of things.
Comfort is not simply whether you are or are not comfy. It's about *how much* comfort you have - My naked Cruiser was comfy... but the FJ is much more comfy. That's what Sports Touring is all about - The powerful performance of a sporty bike with all the comfort of a Tourer!
The FJ has many things about it - One of those is that you just whip the tank off and everything is easily accessibe. You can even turn it rounmd and leave the fuel line connected, which makes sorting the carbs out an absolute doddle.
It's pretty bullet-proof with massive tolerances, parts are cheap and plentiful, fuel economy is still OK by today's standards, and it just has so much character.
