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.
Boss fights are where MX Bikes tests everything you've learned. This guide covers strategies for bosses across all areas, organized by progression order. For general combat techniques, see our combat guide.

Practice Track Bosses
Area difficulty: Easy Recommended level: Any skill level Recommended build: Supercross with MSM 350XF
Strategy
The first bosses teach core combat mechanics. Focus on learning patterns rather than dealing damage. PiBoSo wrote the tyre model, chassis flex and suspension simulation from the ground up rather than licensing an engine. This is your primary tool here.
Key tips:
- Don't rush. Learn the attack patterns first.
- Use Scratch built physics engine to create safe windows.
- MSM 350XF is enough to handle everything here.
MXB Club Bosses
Area difficulty: Moderate Recommended level: Beginner to intermediate Recommended build: Supercross with MSM 350XF
Strategy
Early game bosses test your understanding of Bike setup tuning. Players who skipped learning this mechanic will hit a wall here.
Key tips:
- Bike setup tuning is critical for these fights.
- Farm MSM 350XF upgrades if you're struggling.
- Consider switching to Supercross if your current setup isn't working.
Maryland Bosses
Area difficulty: Hard Recommended level: Intermediate Recommended build: Motocross with MSM 250XF
Strategy
Mid-game bosses are the major skill check. They combine multiple mechanics and punish players who rely on a single strategy.
Key tips:
- You need both Scratch built physics engine and Dynamic terrain deformation mastery.
- MSM 250XF makes a significant difference. Get it before attempting these.
- See our combat guide for advanced techniques.
Winchester Bosses
Area difficulty: Very Hard Recommended level: Intermediate to advanced Recommended build: Motocross with MSM 250XF
Strategy
Late-game bosses are serious challenges. Build optimization matters as much as mechanical skill.
Key tips:
- Make sure your build is fully optimized.
- MSM 250XF at max upgrade is recommended.
- Study each boss's attack patterns. Most have 2-3 phases.
Straight Rhythm Bosses
Area difficulty: Extreme Recommended level: Any skill level Recommended build: Motocross with MSM 250XF
Strategy
Endgame bosses are the ultimate test. They require mastery of all combat systems and an optimized build.
Key tips:
- Top-tier build with best-in-slot gear is mandatory.
- Master every mechanic. See our combat guide.
- These fights reward patience and pattern recognition above all else.
General Boss Tips
- Learn before you fight: Spend your first attempt observing attack patterns. Don't try to win on attempt one.
- Match your build: Some bosses favor certain builds over others. Don't be afraid to switch.
- Upgrade your equipment: A max-upgraded MSM 250XF trivializes fights that seem impossible with weaker gear.
- Use Scratch built physics engine: The core combat mechanic is your best defensive tool in every boss fight.
- Check the walkthrough: Our walkthrough tells you when you're ready for each boss.
