Russian Rider Crashing Silly in the Rain [Video]
The main ingredient for riding safely in the wet is knowing the limits of the bike as far as traction goes. Namely, being able to tell when the tires are beginning to lose grip due to aquaplaning. Having this matter solved (i.e. well-known), it's all down to keep the speed in the decent range for the type of surface, avoid hard brakes or throttling and slowing down in time for turns.
Well, it looks like this Russian rider failed to follow the "drill" and as he tried to turn, the bike elegantly slid away under him. Machine and rider, they both slid out of the camera angle, but it looks like the guy will be alright, save for some scratches and bruises.
