Get Ready for the Next Era!

The Project OEM v0.19.0 MX update is all about pushing the riding experience to a new level. We’ve taken your feedback to heart and focused on making the bikes feel more natural and responsive, especially when it comes to grip and control. With changes to the tyre system and bike mechanics, our goal is to make the ride feel more realistic and connected to the terrain beneath your wheels. The biggest change is the new tyre system, which now adjusts traction based on how much load is on the wheels. This really changes how the bike handles across different surfaces. Whether you’re ripping through corners, navigating hardpack, or clawing your way up a steep hill, you’ll find that small changes in body position, throttle control, or braking can make a big difference in how the bike responds. We want to give you more ways to control the ride and capture that authentic motocross feel. We’ve also fine-tuned the bikes to improve handling, performance, and balance. Changes to steering, power delivery, gear shifting, and braking aim to make every class and model feel distinct while still keeping that familiar control. Whether you’re threading a 250cc through tight sections or letting a 450cc loose on an open straight, you’ll feel the difference. And with updated audio and new 2025 liveries for some models, it’s not just the ride that’s improved—it’s the whole experience.

We proudly present the MX OEM v0.19.0 Update!

One of the bigger updates done to this pack, from reworked rubber donuts to adjusted tuning screws out of the box.

There are no model updates for this update – these will come in v0.19.1. Sorry for any disappointment.

Changelog

Tyres

• New Tyre System: Experience dynamic traction based on wheel load.
  • Wheel load refers to the force exerted on each wheel, influenced by factors like body position, leaning, throttle control, braking, and terrain adaptation.
  • This system gives you direct control over traction, allowing for precise manoeuvres such as power sliding, squaring up, gripping the terrain, and handling challenging sections with confidence.
  • Previously, erosion was inverted, with the deepest ruts forming before the tyres had the most load. Now, erosion matches the highest load, so tyres grip better in both premade and dynamic ruts. Try it out by adjusting the deformation slider!
• New “OEM_MX” Tyre Folder:
  • Introduced a dedicated “OEM_MX” tyre folder. This means OEM bikes no longer rely on the default “P_MX” tyres, improving compatibility with other bike packs. Please delete the “p_mx” folder from your mods/tyres folder!
  • The new folder comes preloaded with Gio’s Dunlop tyre model by default. (Instructions on how to swap tyre models will be available soon.)
• Expanded Tyre Options: Updated and expanded the tyre line up to cover all classes.

Tyre Roster

• Front Tyres:
  • All classes: OEM MX IS 80/100-21
• Rear Tyres:
  • MX1: 110/90 and 120/80
  • MX2: 100/90 and 110/90
  • MX3: 110/90, 120/80 and 120/90
  • MXE: 100/90, 110/90, 120/80 and 120/90

Bikes

• Steering Improvements:
  • Enhanced steering response to match the new tyre system and recent updates in Beta 19.
• Power Delivery Recalibration and Optimization:
  • Fine-tuned power output across all bikes to feature better balance across the board.
• Improved Power to Ground for MX2 Class:
  • Making the MX2 class more viable and fun.
• Temperature Management:
  • Adjusted engine temperature handling for more consistent performance.
• Shift Helper Refinements:
  • Made gear shifts feel more realistic, with a fairer difference between bikes equipped with quick shifters and those without.
• Engine Damage Temporarily Disabled:
  • While waiting for a fix on tyre collision detection by Piboso, engine damage is turned off to prevent sudden failures during races.
• Higher Usability for Gears 4 and 5:
  • Improved the effectiveness of higher gears.
• Stronger Rear Brake:
  • Increased braking power for better control.
• New 2025 Liveries:
  • Updated GasGas, Husqvarna, and Yamaha bikes with the latest PNT liveries.
• Suzuki Shifter Fix:
  • Corrected the shifter’s rotation to the proper orientation.

Audio

• Sound Positioning Improvements:
  • Enhanced spatial audio support for a more immersive experience.

What Is Wheel Load And How To Influence It

In the changelog we’ll mention wheel load – so here’s a brief overview;

In motocross influencing wheel load is crucial for maintaining control, improving traction, and navigating different types of terrain. Wheel load refers to the amount of force or weight applied to each wheel, and you can influence it through the various techniques listed below. By mastering these techniques, you can effectively manage wheel load and with that the traction and handling characteristics it brings forth.

Body Position

• • Leaning Forward: Moving your body weight forward increases the load on the front wheel. This is useful for improving front-wheel traction, especially when cornering.
  • Leaning Backward: Moving your weight backward increases the load on the rear wheel. This helps when accelerating, climbing hills, or when you need more traction on the rear wheel.
  • Standing vs. Sitting: Standing on the pegs raises your centre of gravity and allows for quicker shifts in body weight, giving you more control over wheel load. Sitting lowers your centre of gravity, which can be more stable in some situations.

Throttle Control

• • Accelerating: When you accelerate, the rear wheel is loaded more as weight shifts backward. This can be used to gain traction on the rear wheel, but too much throttle can cause the front wheel to lift (wheelie).
  • Decelerating: Rolling off the throttle or using engine braking shifts weight forward, increasing the load on the front wheel. This is useful for improving front tire grip, especially when approaching a turn or when you need more precise steering.

Braking

• • Front Brake: Applying the front brake shifts weight forward, increasing the load on the front wheel and reducing it on the rear. This is effective for stopping power but requires careful control to avoid locking the front wheel.
  • Rear Brake: Applying the rear brake shifts weight backward slightly, though the effect is generally less pronounced. It’s useful for controlling speed without dramatically altering front-wheel traction.

Cornering Techniques

• • Leaning Forward in Turns: When cornering, leaning forward while applying the appropriate amount of throttle keeps the front wheel loaded, improving front-end grip.
  • Leaning Back on Exits: As you exit a turn and begin to accelerate, shifting your weight backward can help load the rear wheel, giving you better traction for acceleration out of the corner.

Terrain Adaptation

• • Soft Terrain (Sand, Mud): On soft surfaces, you may want to shift your weight backward to help the front wheel stay light, preventing it from digging in or getting stuck. This allows the rear wheel to drive the bike forward.
  • Hard Terrain (Rocks, Hardpack): On hard surfaces, a more balanced weight distribution or even a slight forward shift can help maintain stability and improve steering precision.
  • Premade ruts and dynamic erode: Previously, erosion was inverted, with the deepest ruts forming before the tyres had the most load. Now, erosion matches the highest load, so tyres grip better in both premade and dynamic ruts. Try it out by increasing the deformation slider!

Jumping

• • Preloading the Suspension: Before a jump, compressing the suspension by quickly shifting your weight downward and then pulling up can help balance the bike in the air. Your body position in the air (leaning forward or backward) will influence how the bike lands, affecting the wheel load upon landing.
  • Landing: Upon landing, absorbing the impact with your legs and ensuring your weight is balanced can prevent either the front or rear wheel from taking too much load, which could cause a crash.
