berkeman said:A low-side crash is when you are in a turn and lose traction with your front wheel. That causes the front tire to turn in and slide out, and you fall the short distance to the pavement and start sliding along. It's called the low-side because you fall the short distance to the ground on the side that you are leaning on. Low-side crashes generally don't hurt much, as long as you don't hit anything before you stop, and as long as you don't get run over, obviously.
A high-side crash generally hurts a lot. It usually would happen when you are in a turn and lose traction with your back tire. The back tire starts to slide out, you back off the gas (or brakes) and the tire catches traction, and the bike whips back into you fairly violently. This usually results in you getting launched over the high-side of the bike, which means you fall further and bounce a time or two before you start sliding. You are also on the wrong side of the bike as it chases you down the road.
Thats about what I thought.
My low-side crashes have generally happened because I misjudged the amount of traction available, and lost the front end in a turn. You can sometimes save a low-side by getting on the gas (we do this in dirtbike riding a lot), but it just depends on the conditions. My fastest crash was a low-side at about a buck in Turn 5 at Laguna Seca at one of Reg Pridmore's CLASS racetrack schools. Turns out I put about a dozen thermal cycles on my new performance tires before the class date, and that's a bad idea. Maybe one or two thermal cycles (a commute), but not a dozen. You really learn a lot about traction when riding at a racetrack.
Ouch.
