Consistently hitting your landings just right takes a lot of practice. You have to learn what gear, revs, speed and how hard to hit a jump in order to stick your landing. Two important techniques to practice are launching a jump or absorbing a jump. When launching you help the compression and rebound by spiking your body weight into the footpegs upon compression and then lift your weight out of the footpegs upon rebound. This technique gives you more height and distance.
