we have a little speed-check thing on my park, but the inrun isnt that steep, riding 75 km/h switch (of course not attempting a kicker that fast), and something like 85 forward, mor isnt possible on that one. but i am pretty sure that i am easily riding something like 110 km/h on my ar5s when we get down to the valley, and it isnt that sketchy.
and ive said before, that the racers get at something like 140, but i heard in the meantime, that they get at 150 or so
