rider going way too fast foe his inexperienced.
he did brake b4 impact. but front locked up & rider flew to the truck in front.

when ride superbike, need to:
1) ride at speed that u confident u hav time & distance for braking & maneuvering.

2) make split second decision on when to brake, when to maneuver left or right, when to just left go & slide.

bck in my riding years, few friends died during convoy due to inexperienced.
most common being over estimate how fast he can take a corner.
that's y thinking bck, convoy, doesn't matter bike or car is a stupid thing.
cuz oftentimes, convoy lead by experience rider who knows the road well. he will go fast cuz ego.
rider at the bck, especially inexperienced 1 will hav tough time catching up, hence more prone to mistakes.
