its easier to shoot water droplets than shooting bikes at 150mph

But you are right, good timing helps. But having a higher fps helps more. and having a fast lens helps even more

Sports is easy to shoot, you just need the lenses.
Look up on Google "Sports photography" And I guarantee you in all of the articles you will get referenced "Get out your checkbook"
Sports is the most expensive, but it's also not much harder than other types...
All you need to do is gain access to a closer spot, or a good focusing point, wait for the bikes/cars to drive around, and start shooting.
High fps will just give you 6 different shots of the bike every second...(Each one will be a slight bit different)
Just time it right, get the focus right, and get 1 amazing shot.
If you miss then just wait for another car/bike to come around. Just takes practice and timing...and huge lenses.
