The Modtreme4 has been uncompromisingly optimized for speed and handling. Through innovative adjustments to the housing and overall design, it gives you decisive advantages on the track:

Lightweight Construction

Compared to its predecessor, the Modtreme4 is 3% lighter. This reduces the overall weight of your chassis and improves agility.

Centralized Center of Gravity

The solder tabs have been moved inward, shifting the motor’s mass up to 7% closer to the vehicle’s centerline. This results in better weight distribution along the middle of the car and enables faster left‑to‑right weight transfer.

Premium Hardware

The motor comes equipped with titanium housing screws straight from the factory. This not only reduces weight at the highest point of the motor but also provides a refined look and maximum durability.

Unmatched Precision

As expected from ORCA, the M4 delivers extremely precise throttle response and top‑tier efficiency.

Technical Highlights

• Housing: Optimized design for improved cooling and reduced weight
