ZTMoto Phantom 85 Bicycle Engine Piston Kit

Built for reed valve-equipped Phantom 85 engines, this windowed piston allows the air-fuel mixture to properly flow through the reed valve system for correct engine operation. The Phantom 85 V3 comes stock with this piston design.

IMPORTANT:

• Required when using a reed valve setup
• Standard non-windowed pistons are not compatible with reed valve induction systems
• Compatible with the stock Phantom 85 V3 reed valve setup
• Compatible with aftermarket reed valves using 40mm intake stud spacing

Phantom 85 Wraith Compatibility:

The Phantom 85 Wraith comes stock with a similar piston design, but without piston windows since the engine is factory-equipped as a piston port setup. This windowed piston is required when converting a Wraith to a reed valve intake system.

Compatible Reed Valves:

• OZ CNC Reed Valve
• Phantom 85 V3 Reed Valve
• G2 Style Offset Reed Valve
