SKU: MS651
Avaibility: In Stock

High-performance saw for demanding applications in high-density stands. STIHL anti-vibration system, HD2 filter with an excellent filtering effect, controlled-delivery high-performance oil pump for conveying high quantities of oil; roller chain catcher as standard.


STIHL 2-Mix engine

High power with up to 20% lower fuel consumption compared to conventional 2-stroke engines.

Improved anti-vibration system

Optimum user comfort and control, even when using long guidebars. Approx. 50% less vibration that MS 650.

Easy-to-repair technology

Thanks to smart engineering there is no need for computer software to do repairs.

HD2 filter

This air filter keeps even the finest dust away from the engine, ensuring a particularly long service life. Thanks to its special material, the filter can easily be cleaned by washing, for example with STIHL Varioclean and warm water.

STIHL ElastoStart

Due to compression pressure, jerky stresses occur when starting internal combustion engines. The damping element in the ElastoStart special starter grip alternately absorbs and releases force according to the compression pattern. The result is smooth, even starting.

Tool free fuel caps

Special caps to open and close the tank cap quickly, easily and without tools.

Decompression valve

The decompression valve is part of the easy starting system. The valve should be pressed before starting to reduce the compression pressure when starting, as well as reducing the effort needed to pull the starter rope. The decompression valve is semi-automatic; it must be pressed manually before starting, but then closes automatically.

STIHL Ematic System

Compared to conventional bars without Ematic, the STIHL Ematic system reduces the consumption of chain lubricant by up to 50%, depending on the type of wood and the cutting attachment used. This system comprises a STIHL Ematic or Ematic S guide bar, a STIHL Oilomatic saw chain and a variable-flow or reduced-flow oil pump. As a result, virtually every drop of chain lubricant is delivered to exactly the right spot.

Side-mounted chain tensioning

Side-mounted chain tensioning makes it easy to tension the chain safely.


Controlled-delivery oil pump

Different bar lengths, wood types and sawing techniques require different amounts of oil. The controlled-delivery oil pump allows the user to select just the right amount of oil for the job at hand.
