MX Bikes is PiBoSo's motocross simulator, running on a scratch written physics engine with an automotive industry tyre model, chassis flex and terrain that deforms as you ride it. It arrived on Steam Early Access on October 7, 2019 and still ships with no AI opponents and no career mode, which leaves online servers and hotlapping as the whole game. Five MSM bikes and a short official track list come in the box; everything beyond that comes from the modding community.
Choosing the right build shapes your entire experience. This guide breaks down every option: what they're good at, what they struggle with, and which one matches your playstyle. For optimized builds with full gear sets, see our builds guide.
