New to the sport, don't have a bike yet so forgive my noobness plzthx
I've noticed that at least half of those crashes were in the corners. Now correct me if my hypothesis is wrong, but I see the rear tire slide out and then I guess the riders instinctively stops accelerating which allows the rear to catch traction again. When this happens the front and the rear tires are out of alignment resulting in the bike re-aligning itself causing that jolt which sends the poor soul over the handlebars.
What are they doing wrong that slides the rear out in the first place?
