    Ain't even close to the same thing as gravel, sand or mud. Plus I'm not doing 80--100 on those surfaces.

    Crossed it a few times on a moto, it's always "exciting." I do like being able to look down through the grate to the water below - kind of gives you the feeling of flying. And maybe a little vertigo thrown in for fun. :D

    This thread bump is timely. I was riding home on the GS from Grand Rapids (to Detroit) last week and thought I'd lost a front wheel bearing or the steering head had gotten loose or who knows what. I am running Tourances. There was this persistent wiggle in the front end. Sounds like it could just have been the pavement grooves, as it's not there now.

    FWIW, the size of the tread blocking versus the width of the grooves or size of the openings in an open deck will dominate the tyre behaviour. If the blocks are 2x or greater, there will be little impact. If they are 0.5x or smaller, also less impact. Around 0.67 to 1.5, all hell will break loose. It can be broken down to relatively simple harmonics. Also, think of a car with very wide tyres tramlining on a road with deep tyre tracks in it.

    No idea, I've never seen a Karoo T in person.

    Waaay back in the '70s, I remember reading in Roger Hull's Road Rider magazine that when California put in the first grooved roads, the first motorcycle to have an accident because of them was a California ChiPs bike.
    A bit ironic I thought. :rofl

    Ride a lot of soft sand. Grooved pavement will then seem like ideal road.

    With time and experience, you won't give grooved roads a second thought. Same thing with steel grid on bridges, providing it isn't wet. There is plenty of grip on both. Relax, let the tire wander a bit and enjoy the sensation.

    Not sure what the deal is here in Idaho. New stretch of freeway was grooved concrete from day one. Now they are resurfacing all concrete bridges and overpassed and the finished product is grooved. Not terrible but takes some getting used to.

    Slow down if needed(it's not a sin or threat to your manhood). Relax stay loose on the grips/controls and let the bike track. Adjust your speed and riding style to the conditions you're currently dealing with.
