Stihl MS881 Bar Length

The STIHL MS 881 Magnum represents the pinnacle of heavy-duty commercial cutting power, holding the title as the world’s most powerful series-production petrol chainsaw. Engineered specifically for forestry professionals, logging contractors, and sawmill operators, this high-output powerhead delivers exceptional torque and cutting capacity for felling massive hard timber, processing thick logs, and heavy-duty rip-sawing applications.

In the Australian market, the STIHL MS 881 is supplied across multiple guide bar length configurations to suit varied commercial requirements, ranging from the standard 63 cm (25 inch) Rollomatic ES bar up to 75 cm (30 inch), 80 cm (32 inch), and extended 90 cm (36 inch) Duromatic bar options. Powered by a 121.6 cc 2-MIX engine generating 6.4 kW of output, it runs heavy-duty .404″ pitch saw chains designed to handle maximum mechanical force with minimal flex. Equipped with an advanced HD2 air filter, decompression valve, and an anti-vibration dampening system, the MS 881 maintains peak engine efficiency and operator comfort during extended, high-intensity operations.

Key Features

• Multiple Bar Length Options: Available with guide bar configurations ranging from 63 cm (25″) up to 90 cm (36″) to accommodate extreme-diameter timber harvesting.

• World-Class Engine Performance: Massive 121.6 cc STIHL 2-MIX engine produces 6.4 kW (8.7 hp) and 8.0 Nm of torque for unmatched cutting speed in dense Australian hardwoods.
