A very interesting new vehicle: Jason Scherer’s 2025 KOH racer. This is one of the highest-quality mods in this category, featuring an exceptional level of detail. It is an accurate replica of the real-life machine and handles brilliantly.

In version 2.0:
Configurations
- New 2026 race configuration featuring new wheels, 42-inch tires, and a 74Weld livery.
Slot Configurations
- Each model year (2025 and 2026) is now tied to its real-world drivetrain configuration and exterior appearance. This means different liveries come with specific RPM limits, transfer case gear ratios, StarLink systems, antenna setups, and wheel/tire combinations (including the spare).
Cockpit
- All cockpit switches are now functional: battery master switch, ignition key and start button, fuel pumps, engine/oil/transmission cooling fans (AUTO/ON/OFF), helmet blower, headlights, siren (mapped to the HORN key), pit-lane speed limiter (via CAL SELECT and OK ALARM). Keyboard buttons now light up when hovered over, and the keycaps have been redesigned. New key bindings have been added for ignition, starting, headlights, the siren, Live Valve, and the winch. The gear shifter now allows for manual shifting up to 4th gear. Includes a MoTeC display and GPS. Features a reverse gear and a dedicated reverse button. The PDM (Power Distribution Module) now displays a feed from the rearview camera. (Note: The camera has a significant impact on performance and can be removed via the frame slots.) The MoTeC C187 dashboard has been overhauled to include authentic "RACE" and "WARM-UP" pages, a warning light array, and functional LEDs (monitoring voltage; water, oil, transmission, and torque converter temperatures; as well as oil and fuel pressure). Gear shift indicators have been fixed; the redline and shift point now track with the rev limiter. A rearview camera feed is displayed on the MoTeC unit and activates automatically when reversing. The instrument cluster no longer glows excessively bright at night. A new Lowrance GPS screen has been added.
Lighting
- All lights have been reworked using real-world output specifications: Baja Designs LP6 Pro units (in Driving/Combo or Spot configurations), plus RTL rear lights.
Fox Live Valve
- Functional Live Valve system with 5 modes: Rock Crawl, Nuisance Rock, Desert, and 2 qualifying modes. Includes front-mounted full-compression and full-rebound adjustment knobs. Calibration sliders for ride-height retention are available in the settings for each mode (front and rear). On-screen prompts explain each mode upon selection. - Suspension: Long-travel front bypass shocks. Fixed a tube-related malfunction; coilover damping adjustment is now functional, with a softer base tune. Corrected a missing 7-degree kingpin inclination angle. Front rubber bump stops now provide proper travel. Shafts are modeled after real-world counterparts. Coilover crossover rings move in sync with the crossover slider. Strengthened upper rear control arms and lower front control arms. Reinforced lower front ball joint. Softer rear sway bar.
Shock absorber sounds.
- Realistic check-valve clicks, Live Valve solenoid clicks, and nut-to-bump-stop impacts. Distinct interior and exterior sound profiles that attenuate with distance.
Winch.
- Fully functional Warn Zeon 12-S winch: features power-in/power-out, a freespool handle, and a synthetic rope. The rope snaps under a 12,000-lb load; upon failure, the remaining portion retracts onto the drum. Pulling force decreases as the rope spools onto the drum, mimicking real-world operation. The hook can be anchored to the ground, rocks, or other vehicles. The hook glows red when you aim the winch attachment point at it, and it is labeled "Winch Hook" when extended. It includes sounds for the motor, freewheeling, stopping, and jerking. The winch draws power from the battery.
Drivetrain Damage
- Driveshafts, CV joints, gears, differential gears, and portal gears can break under impact loads. Front CV joints become weaker at sharp angles. Damaged gears crack and chip; missing teeth cause intermittent drive and can lead to the drivetrain seizing. Broken front half-shafts now disappear from the vehicle.
Engine and Electrics
- Dry-sump lubrication system: functions correctly when the vehicle is on its side, but experiences oil starvation when upside down—resulting in smoke, a knocking connecting rod bearing, and eventually, engine seizure. The battery is charged by an alternator; if the battery is depleted, the starter will only click, and the MoTeC display will trigger a low-battery alarm.
Driver and Cameras
- Driver figures are present in both seats, equipped with safety harnesses and HANS-device physics (reducing head movement during impacts and landings). The driver-view camera no longer shakes.
Physics and Fixes
- Body panels now deform rather than exploding upon hard front-end landings. The rear driveshaft now has collision properties, preventing rocks from passing through it. Fire extinguishers are mounted correctly and no longer fall off. Brakes are more powerful, featuring racing pads and improved cooling. The driveshaft is now slightly more durable. Fixed an issue where the vehicle would overlap the Bolide's interior material.
