A 4-stroke, 123cc Overhead Valve engine is the heart of the YP20. This mid-range pump can move up to 600 litres/minute through a 2-inch port. It's engineered for long life with features like auto shut-off, low oil warning, and more.
Auto decompression system reduces engine compression to provide a light recoil starter pull for effortless manual starting.
Maintenance-free transistorized controlled electronic ignition (TCI) provides a hot spark for fast, easy starting.
Cast iron cylinder liner provides excellent heat dissipation for consistent performance and long engine life.
Yamaha's Oil Watch Warning System automatically shuts off the engine when oil level is low and will not re-start until oil is added, preventing costly engine damage and enhancing long-term durability.
