Moto X3M Ultimate Speedrun Handbook: Physics Mechanics & 3-Star Guide (With Visuals)

Chapter 1: Counter-Intuitive Core Mechanics
Front Wheel Landing: Causes the bike to bounce, or even flip over due to the center of gravity shifting forward (Wasted). Rear Wheel Landing: The physics engine registers this as "shock absorption." Not only will you not crash, but you will also receive an instant forward thrust boost.

A Losing Deal: If you intentionally slow down to set up a flip, or waste 1 second adjusting your posture upon landing, you have actually lost 0.5 seconds. The Winning Rule: Only use flips on large parabolic terrains with airtime clearly exceeding 1.5 seconds.

The Principle: In the game, the friction resistance of the front wheel is higher than that of the rear wheel. Driving on the rear wheel alone is about 10%-15% faster than driving with all wheels on the ground.

Chapter 3: The Metaphysics of Bike Selection
Classic Red Bike: Stability ⭐⭐⭐⭐⭐ | Speed ⭐⭐⭐ Ninja Bike: Agility ⭐⭐⭐⭐⭐ | Stability ⭐⭐ Ghost Bike: Grip ⭐⭐⭐⭐ | Hitbox ⭐⭐ Classic Red Bike: Has the most stable center of gravity. Perfect for first-time clears on complex terrain (like the tunnels in Level 15). Ninja Bike: Rotates extremely fast; a slight tap of the arrow key can spin you around. It is an artifact for grinding leaderboard ranks, but it is extremely easy to "over-rotate" and faceplant.
