If anything the opposite trend makes more sense, the motard / supermotard style where a competent off-road bike is retrofitted with road tyres and suspension tuning. They look like an absolute blast.
>At least they're not as silly as the trend of sticking knobbly tyres on road bikes for that "scrambler" look.
FWIW I've got a mid-weight streetfighter that I'd love to put some 50/50 tires and a skid plate on. But I already take it into the dirt so it would be an improvement.
And yes, supermotos might be the ultimate motorcycle.
A buddy of mine dropped his s1000rr coming out of a right turn at a traffic light and was up for around $8k in damages... He was only going ~10mph. I envy those who can fix their bikes after dropping them for $20 when they didn't even have frame sliders etc.
660cc single-cylinder that you could just beat on all day without breaking the law too much, plus super long suspension travel and fat sticky road tires made for a bike that just ate up speed bumps and rough roads. I pulled some gnarly wheelies over bumps and cresting hills, so much fun.
And it was obnoxiously orange, I loved that bike. It was a shame someone else decided that he liked it more and cut though a massive Kryptonite chain to get it.
I think the most interesting take-away is that there is a segment of people who value being given an excuse for something rugged— I heard lots of "I just like the peace-of-mind that I could go anywhere if I needed to" whether they believe themselves or not.
Not a motorcyclists but I assume these adventure/dual sport bikes perform much better over say unsealed roads, and are at least workable on fire roads.
So yeah, ADV would seem to be useful for something other than wanting to look rugged.
Single track is hard work but there's nothing quite like ripping open the throttle on a 100hp dirt bike and throwing up a tornado of sand. I owned an XR250R for a few years and just found it boring.
