Rotax Max EVO Cylinder – A Bore – QR Code – 413530 (Micro / Mini / Junior MAX)

Brand new Rotax Max EVO cylinder, part number 413530, A bore size, featuring the factory laser-etched QR code and ROTAX RACING branding.

This is the current production EVO cylinder used as the base engine component for 125 Micro MAX, 125 Mini MAX, and 125 Junior MAX classes. Under Rotax regulations, the Junior MAX engine configuration is the foundation for both Mini and Micro, with class differences controlled by external restrictions — not by the cylinder casting.

Key Features

• Genuine Rotax factory cylinder

• A bore size (standard new-cylinder bore class)

• Latest EVO specification with QR code

• Correct 413530 identification code

• Single main exhaust port

• No exhaust valve (Micro / Mini / Junior configuration)

• EVO-style extended CNC-controlled port finishing

• Uniform cast transfer ports and passages

• Original factory finish — no machining, no honing, no rework

QR Code & EVO Identification

All current EVO cylinders are marked with:

• ROTAX RACING logo

• Laser-etched QR code for authenticity and traceability

The QR code confirms:

• EVO generation cylinder

• Genuine Rotax production

• Compliance with current technical regulations

Cylinders without a QR code are not current EVO specification.

Applications

• 125 Micro MAX

• 125 Mini MAX

• 125 Junior MAX

Not for Senior MAX or DD2 (those require exhaust-valve cylinders with different ID codes).
