hurting ankles on landings
Hey Vegas, I think I can offer you some advice that may help.
First. Try changing your foot position on the pegs, on really hard landings
you could easily break your ankles with your balls of the foot on them.
Put the middle of your boot on the pegs instead. This should help a lot.
Second. When you land on a tabletop, try to have your bike in a neutral
position in the air, in other words the bike is level.
Right before you land, give the bike some throttle, this will help the rear
suspension take the force of that landing. Which will result in a much
smoother landing. Which will also result in you having a better time at
the track.
Let Us know if these things helped.
