Rotax 125 Max DD2 Evo

The engine for everyone aged 18–100+

What sets the Rotax DD2 apart from other kart engines is the absence of a chain and the smooth paddle shifters mounted directly on the steering wheel.

Closer Racing

After 15 years, the major update to the Rotax Max engines finally arrived — EVO.

The new engines still use the same crankcase and cylinder as before, but Rotax has added color accents to the crankcase and cylinder head for a more modern appearance. Performance remains the same, but is now much more consistent than before. The engine delivers peak performance straight from the factory.

Thanks to the EVO update, the engine received fantastic throttle response, while previous issues with misfiring and detonation have been eliminated.

Carburetor

The new carburetor marked “XS” provides significantly improved throttle response out of corners. It is easy to tune and requires far less fiddling with jets and adjustments.

Electronic Control Unit

Specific ECU for the DD2 with an optimized ignition curve for the engine.

Electronically Controlled Exhaust Valve

The exhaust valve is controlled by the ECU and opens using vacuum pressure. This means it requires no manual adjustment from either the driver or mechanic.

Battery Holder

With an integrated and combined switch (OFF / ON / START) — reducing installation complexity on the chassis and making it easy to operate.

Exhaust System

Featuring a split rear silencer and exhaust system for reduced noise levels and improved durability. Also lower in weight.
