Good thing he didn't slip usually those are slimy!

Im pretty sure it would be easy to make a formula based upon the bike + rider weight, acceleration due to gravity, drag due to wind and water, velocity of the rider, and surface area of the tires in contact with water.

Alright, do that and get back to us. You can kinda tell you just wiki'd that too - if you knew physics you wouldn't be talking like that lol

Hydroplaning does have a set speed, actually. It's 70kph for cars I know that for sure. Bikes may be different but I can't say for sure.

There is no "set" speed at which hydroplaning "starts". It depends not only on speed but also on the pressure the area contacting the water exerts (i.e. a boat technically is "hydroplaning" at all speeds because it floats).

I'm sorry, my perspective on reality has been warped by being here at the world's #1 public uni for engineering... 
SUCK IT!!! WOOO.

Definitely did NOT just wiki that... I just thought you could make a formula from those. Engineering student here as well.

Of course you can 
. But not if you don't take the tire tread into account: massively important factor. Especially for a car, if you fit some regular car with slicks you can make it hydroplane at as low as...I donno, 40mph?
When it's raining really heavy, when there is a good layer of water on the highway, check out the spray of water other cars' tires are creating. You can see huge differences in how they handle the water. Some have very little spray forwards and sideways and seem to be riding through effortlessly, while other tires are already pushing massive amounts of water forwards, in front of themselves. They look like a boat ploughing through inefficiently. It's real easy to tell who's going to hydroplane first.
btw. Aerodynamics/'wind drag' don't matter shit. If you are going fast enough to aquaplane, you are going to, whether the wind is blowing with 300mph or not. It matters only when you want to know what's going to happen after you have started hydroplaning. Which would be a massively complicated differential equation .
Trust me, I'm an Engineer :p

you were going so well up until the last paragraph. aerodynamics would increase the speed that aquaplaning takes place. increasing downforce would increase the pressure on the tires thus resisting the force of the water trying to get underneath the wheel and lift the car up.
Also an engineer
Also cool pic

Right.
The point is contact area and pressure ...Believe me, I just had it in college

Surely such an equation would involve some really really gnarly surface integrals, one that would probably be impossible to analytically solve.

I'm not an engineer or anything, but I definitely know what hydroplaning is.
It's when you place two rabid squirrels in an arena together with combat-knives and stake bets on who will win first, then you take the winning squirrel, crown him as your king and form a religion around him and anyone who doesn't like it gets put into the ring with the squirrel-king and fights to the death, eventually you gather all the bones of the defeated heretics and create a bone-castle for the squirrel king to live in and fornicate with the other bangin' hot squirrel chicks.
True story.

f*ckin nerds dude. 18 messages about hydroplaning and physics?
go discuss this in another website.
sick little spot tho

at least road bikes cant.... i've gone way over 80 in the rain and I was fine.... damn cold though in that short sleeve jersey

great another useless and totally worthless conversation that has noting to do with the vid. Keep it up boys!!

Hydroplaned in a car that was only doing 60km/ph so yah, it is pretty easy to hydroplane, it has to do with the amount of water between your tires and a surface, the water essentially creates a frictionless barrier and you fly around the place. Not so much to do with speed.
