STIHL MS 170 Vs MS 171 : What You Need To Know

STIHL MS 170 Vs MS 171: Both of them are 2-stroke, air-cooled chainsaws with a 16″ bar and chain. They have a similar design, with the same safety features, but there are some differences that may make one better than the other for you. The MS 170 has a 14.5 cc engine while the MS 171 has a 15 cc engine. This means that they both have enough power to cut through a variety of materials easily, though the larger engine allows for more torque and therefore more cutting power.

The MS170 is a light, powerful chain saw for homeowner use. This unit is ideal for cutting firewood and for light clean up tasks around the yard. It features a high power-to-weight ratio and STIHL anti-vibration technology to reduce operator fatigue. The MS 170 also features redesigned ergonomics that improve operator comfort, including a low vibration handle and carburetor preheating system for quicker starts in colder weather. 


The STIHL MS171 is the latest evolution of the successful MS170. With its improved performance, the new model offers a better balance between power and weight. This makes it a good choice for smaller cutting jobs.  

This stihl chainsaw features an anti-vibration system that reduces vibration at the handle by up to 25%. It also has a low noise level which makes it suitable for use in residential areas as well as commercial sites where noise pollution is not allowed. 

Engine Displacement

The MS 170 has a 24 cc engine while the MS 171 has a 26 cc engine. Engine Displacement The main difference between these two models is their engine displacement. While they both have an 18″ bar and chain, one model has a 24 cc engine while the other has a 26 cc engine.

The larger displacement allows for more power from each pull of the trigger, but also increases fuel consumption slightly due to increased heat generated by the increased compression ratio of larger engines. 

Power output

Both chainsaws have an engine power output of 0.75 kW, but the MS 171 has a slightly higher maximum cutting speed than the MS 170. The maximum cutting speed for the MS 170 is 8,000 RPMs and for the MS 171 it is 9,000 RPMs. However this difference isn’t likely to be noticeable when you are using either chainsaw on trees or small branches as both machines can cut through wood at this speed without any problems.


The Stihl MS 170 and MS 171 are both light weight chainsaws commonly used for cutting firewood, pruning trees and other small yard work. As far as weight goes, they are virtually identical. The Stihl MS 170 has a dry weight of 5.9 lbs while the upgrade, the MS 171 has a dry weight of 5.8 lbs. Both weights include an empty fuel tank and bar/chain oil reservoir but do not include the guide bar or chain itself.

Power-to-weight ratio

The MS 170 has a power-to-weight ratio of 0.45hp per kg. This is quite low compared to other chainsaws in its class, but it’s still enough to make short work of hardwood and softwood trees. The 171 has an even lower power-to-weight ratio of 0.27hp per kg, which makes it one of the lightest chainsaws on the market today.

Sound pressure level

Sound pressure level (LpA) is the primary difference between these two models. The MS 170 has a sound pressure rating of 98 decibels, which is about as loud as a household drill. Some states require hearing protection to be worn at this level, so it’s best to check your local regulations.

The MS 171 has a lower sound pressure rating of 94 dB(A), which is about as loud as a food blender. This means that no hearing protection is required in most states when using this saw, and you’re less likely to disturb your neighbors and other people around you with excess noise.

Sound power level

The sound power level is a measure of how loud the machine is when it’s running at full throttle. The STIHL MS 171 has a sound power level of 93 dB(A), while the STIHL MS 170 has a sound power level of 95 dB(A). So, if you’re looking for an extremely quiet chainsaw then don’t get either of these models because they can be quite loud! 

Vibration level left/right

The STIHL MS 170 weighs just over 12 pounds and features a telescopic handle that allows you to adjust it depending on your height and size. It also comes with an anti-vibration system which reduces fatigue during use by up to 50%. Finally, this model offers excellent safety features including an anti-kickback bar that prevents kickback if you hit something while cutting or an integrated oil pump.

The STIHL MS 170 has a lower vibration level than the STIHL MS 171. This means that it will be easier to handle and operate for long periods of time without causing fatigue or pain in your hands or arms.

Saw chain pitch

The pitch refers to the size of the drive link where it connects with a sprocket tooth. The pitch is expressed in inches, starting with 1/4” pitches, although 3/8” pitches are becoming more common in chainsaw models.

Choosing a saw with a less common pitch can make it difficult to find replacement parts, so it’s best to choose a model that uses a common pitch. The STIHL MS 170 is equipped with a 3/8″ PM3 saw chain. The MS 171 is equipped with a 3/8″ Picco Micro 3 saw chain. 

STIHL MS 170 vs MS 171|which is more better

Both are lightweight, economical chainsaws with a great warranty. However, the MS 171 is a more advanced version of the 170. Both models have an anti-vibration system to reduce operator fatigue when using them over long periods of time. They both have an automatic oiler to keep your chain lubricated so it doesn’t get damaged by friction or heat during operation.

The STIHL MS 170 is a small, lightweight saw designed for cutting firewood and general clean-up tasks.Both models are part of the Homeowner series of chainsaws. The MS 170 and MS 171 are powered by gas engines, which means they produce fumes you’ll want to be careful not to inhale while operating the saw.

MS 170 Vs MS 171


The MS170 and MS171 are both lightweight chainsaws but they still pack enough punch to get most cutting jobs done. While the 170 and 171 are extremely lightweight, they are also well balanced which makes them easy to control while working with them.
