The Robin EX27 (often marketed under Robin-Subaru) is a heavy-duty, commercial-grade 9.0-horsepower petrol engine. Stepping up in displacement from the EX21, the EX27 is engineered to provide high-output power, exceptional torque, and reliability for demanding industrial, construction, and agricultural equipment.
Key Technical Specifications
Engine Type: Air-cooled, 4-cycle, single-cylinder, Chain-Driven Overhead Cam (OHC), horizontal PTO shaft
Displacement: 265 cc
Maximum Output: 9.0 HP (6.6 kW) at 4,000 RPM
Maximum Torque: 18.6 to 18.7 Nm (approx. 13.7 ft-lbs) at 2,500 RPM
Fuel Tank Capacity: 6.1 Liters (approx. 1.6 US gallons)
Oil Capacity: 1.0 Liter (34 oz.)
Dry Weight: Approx. 21 kg (46 lbs)
Starting System: Available in standard recoil start or electric start configurations
Standout Features & Benefits
Chain-Driven OHC Design: The overhead cam configuration optimizes valve timing and combustion efficiency, resulting in lower fuel consumption and cleaner emissions compared to legacy side-valve engines.
Industrial Durability: Features a robust cast-iron cylinder sleeve, a dual ball-bearing-supported forged steel crankshaft, and a high-grade aluminum block built to withstand high loads and prolonged run times.
High Torque Curve: Delivers strong pulling power at lower RPMs (peaking at 2,500 RPM), making it ideal for machinery that encounters sudden heavy loads.
Refined Acoustics & Balance: Precision engineering reduces engine vibration significantly, while a large-capacity, soft-tone muffler keeps operational noise levels down.
Common Applications
Because of its heavy-duty output and dependable performance under stress, the EX27 is widely used for:
Log splitters and commercial wood chippers
Large pressure washers and trash water pumps
Medium-to-large portable generators
Go-karts and specialized turf/agricultural machinery
Concrete saws and heavy plate compactors
