How do motor cross riders know how fast to hit a ramp/jump to land safely on the downramp?

Like, how do they figure out how to not overshoot or case it? Was just watching a guy hit a heap of jumps in an arena and he got every single landing perfect.

For smaller jumps of, say 20-40 meters you can kind of get sense of speed based on trial and error and experience. The suspension of the bike gives you enough margin for error.

You can also design jumps in such a way that they’re tolerant of varying errors in airtime.

For very large jumps you want to measure the exit and landing ramp angle then get someone with engineering knowledge knows how to massage the relevant physics equations and can give you the exact speed you need for landing. Believe it or not air drag starts to become an important factor in those equations faster than, say 80km/hr
