This Stage I kit is designed for touring and custom bikes seeking a freer intake without complicating installation: a single-piece aluminium support plate, chrome finish, and pre-oiled round element for quick preparation before fitting.
- Design: Stage I, round shape with a “Big Sucker” profile for unobstructed airflow.
- Material & finish: Aluminium with chrome finish, silver colour.
- Integrated ventilation: concealed breather with O-rings at the heads leading to the injector/carburettor side — effective ventilation without external hoses.
- Compatible: installs with the OEM air filter cover.
- Ready to fit: pre-oiled; all mounting hardware and instructions are included.
Designed to maintain a tidy line while improving airflow to the intake, this kit retains a discreet integration thanks to the concealed breather technology.

Ideal for riders who want a high-performance intake and a custom look without technical complications.
