Yes... motorcycles aquaplane, or hydroplane as you say over there....
I was returning home late one night down the Argyll Forest road, my front tyre was down to about 1.5mm remaining tread depth... very near due changing... it was very wet and still raining..... and several times I felt the front lift, once or twice into sweeping right hander's where water was puddling on the road..... very, very, disconcerting.... my biggest concern wasn't the aquaplaning, but that the front wouldn't regain grip before running out of road... sideways....
It's an odd feeling when you feel the bars go "quiet" for a split second...... but you get sort of used to it, almost anticipating it in certain conditions and adjusting your riding to suit...
The harder the rain and the deeper the surface water, alongside the shallowest of front tyre tread depth, makes for an exciting ride......
Seldom happens with the rear unless it is very near a slick.... as the front clears the way, even when it is itself almost done..... tyre pressure also plays a significant part in this phenomenon...
