Let's say you're riding down the highway in a sportbike when suddenly the road turns into a river. Will you and your motorcycle survive? It's possible!
At least this one Dutch rider made it out of a surprise bike wash on the way between Amersfoort and Zwolle. Here's the rider's description of the run on the video he uploaded back in 2012.
It started raining when I was returning home from a very nice touring weekend with some friends. About 30km from home I noticed a traffic jam ahead and when I was about to turn on my warning signals, I ended up in this situation
A part of the highway was flooded because of heavy rain. My visor was dirty and I couldn't see the road clearly while I was focusing on the traffic jam in front of me
Something tells me his visor wasn't the only thing that was dirty after that run.
