I dont think they should cause any problems on a MC.

At some exits they have them across the whole lane, so you dont slam the toll booths at 80mph.

might scare the kwrap out of you though...

thing is you cross those at 90 degrees not at an angle like what you would have to do on the shoulder ones, i'v crossed the shoulder ones at 45 or 50 and they grab you pretty good at that speed but recovery is easy, i guessing at a certain speed recovery might not be possible, like if you had to use the shoulder to get out of trouble with no time to slow down before crossing that strip.

I googled this a bit today and I dont see any indication of danger to MC riders.

They also put them on the center line on some two lane roads so you dont cross into on coming traffic.

They are dips or bumps scalloped into the asphalt, and they dont have any directional component to them. Not like when they groove the pavement to put down new asphalt, or the gratings on steel deck bridges.

It might deflect your steering angle a bit but I dont think it would be enough to knock the wheels out from under you, like hitting a median or a curb. Motorcycles are incredibly stable because of the gyro forces of the spinning wheels, esp at highway speeds. It would take a tremendous force to knock a motorcycle over sideways.

Now Im going to have to find a road with rumble cuts in the center line and try it. (no officer, I have not been drinking...)

I've crossed over the center ones on a two lane just to see what they do. It's a rough ride just like in a cager but not something that will put you down. To me some steel bridge grates are worse.

i'm worried that crossing one at speed could cause an unrecoverable tank slapper

I dont think a properly designed, maintained (wheel bearings, steering head..) and loaded MC is able to get into a tank slap instability.

Its an interesting topic, Ive never seen any thorough studies on tank slap.

I hit one at 75 and didn't have any issues...it's a rough ride for sure, but it wasn't anything I couldn't handle.

I haven't hit them on my bike, I'm sure they are no fun, but not likely inherently dangerous to MCs. I'm sure they are more safe than not having them. One day while riding my sport bike I woke up and realized I needed to take a break. It wasn't a long ride or anything, I just wasn't getting good sleep in those days. If the road i was riding on had the rumble strips I probably would have been better off.

The US60 west from the east valley into Phoenix has a nasty groove down it in one lane. It goes for miles and is scary as heck on my bike. I'd take rumble strips over it any day of the week.

If you ran over rumble strips on a MC with straight pipes at 80mph

how would you know?!

Groovy Baby! means the opposite on a motorcycle...

we get them in upstate NY where the paving lines between rows with the asphalt truck freezes and thaws, and blows out about 3 inches wide and deep between the lanes on the road.

Sometimes the yellow lines hide them - not good when passing....
