Stihl MS 171 Vs MS 250

The STIHL MS 250 is a mid-range chainsaw that’s easy to handle and tough enough for most applications. The outer shell of the machine is constructed from impact resistant plastic, and the engine is built to last with sturdy components like a forged crankshaft, chromium-lined cylinder bore, and ball bearing supported crank shaft. It’s small enough to use comfortably even if you have very little experience with large power tools, and it’s safe to use even in close proximity to other people or flammable materials.

This model is one of STIHL’s most popular chain saws, and there are many reasons why. First, it has an X2 air filtration system that can last up to five times longer than other brands of filtration systems. This means more time between filter cleanings, resulting in less downtime and more work time. Second it has a larger fuel tank than other comparable models on the market which gives you more time in between fill-ups, meaning you have more time to get your job done before having to stop and refuel.

Third, this saw has an anti-vibration handle that reduces fatigue on your hands and arms by absorbing vibration from cutting logs or branches while still allowing full control over the saw’s movements during use.


MS 171 is essentially a more powerful version of the MS 250, but its advantages go beyond just an increase in horsepower. The engine has been designed with a number of features that make it more efficient and therefore more powerful than its predecessor. One improvement is the new piston ring design, which allows combustion gases to flow more freely; another notable change is that the carburetor has been redesigned so that fuel flows faster into the engine than before.

The exhaust manifold on the MS 171 is made of cast aluminum which can handle higher temperatures than a steel manifold. This allows the MS 171 to run hotter and cleaner at full throttle, resulting in less emissions.The fuel cap on the MS 171 has a venting system that reduces evaporative emissions when refueling.

The vent opens automatically as you put gas in, and it closes normally after fueling. This prevents excess vapors from escaping into the atmosphere and keeps your engine running more efficiently. Adjustments can be made to the carburetor on both models but only if something goes wrong with the carburetor or if you decide to tinker with it for other reasons.

STIHL MS 250 vs MS 171 |Engine Displacement

The 250 has an engine displacement of 2.8 cubic inches, while the 171 has 3.0 cubic inches of engine displacement. This means that the 171 will produce more power than the 250—but only by a small amount.

The MS 171 has a larger engine displacement than the MS 250, the displacement doesn’t necessarily mean that one saw is better than the other. In fact, in some cases, a larger engine size can make a chainsaw harder to use and less efficient.

STIHL MS 250 vs MS 171 |Power output

Power output:The STIHL MS 250 has an engine displacement of 45 cc, which is good for an output power of 3.0 bhp (2.2 kW). Meanwhile, the STIHL MS 171 has an engine displacement of 50.2 cc, which gives you an output power of 3.

One of the main reasons people buy a chainsaw is for its power. They want to be able to cut through thick logs and limbs without having to exert their own energy. That’s why the power output of both the STIHL MS 250 and MS 171 are important considerations when choosing between them. Both of these chainsaws have more than enough power for the average homeowner, but there are some differences between them that may make one better suited for your needs than the other.

STIHL MS 250 vs MS 171 |Weight

The MS 171 is a heavier saw than the MS 250. The MS 250 weighs in at 11.3 lbs, while the MS 171 comes in a little heavier at 12.3 lbs. When you’re working for long periods of time with an axe or a chainsaw, every extra ounce is important. You’ll feel that extra pound on the MS 171 at the end of the day, and you’ll be more fatigued if you don’t have help with your projects. However, for smaller jobs and lighter tasks, the difference will be negligible.

The STIHL MS 250 and MS 171 chainsaws are part of the same family of saws, but there are some differences you should be aware of before you decide. Both saws are excellent for occasional home use in a variety of applications, including firewood cutting, limb removal and storm cleanup. They’re also both lightweight, have a side-access chain tensioner and come equipped with an advanced anti-vibration system to keep you comfortable while you work. But if you decide on the 171 model, you’ll also get a number of additional features. The most notable difference between these two models is that the MS 171 has more power than the MS 250.

It comes equipped with a longer guide bar (20 inches compared to 16 inches) and is designed to take on larger jobs like clearing brush or trimming small trees. The 171 also features STIHL’s Easy2Start system for simplified starting, as well as a Quick Chain Adjuster for fast chain tensioning without tools. This model has a fuel-saving EcoBoost engine design that reduces fuel consumption by up to 20% and emissions by up to 50%. Finally, it’s equipped with the STIHL Quickstop inertia chain brake which stops the chain in fractions of a second if kick.

STIHL MS 250 vs MS 171|Power-to-weight ratio

The MS 250 is a lightweight saw with a power-to-weight ratio of 1.9 kg/kW, which makes it ideal for felling small trees, pruning and thinning, and cutting firewood simply and efficiently. The MS 171 is also a lightweight saw with an even lighter weight-to-power ratio of 1.7 kg/kW. This extremely low weight makes the MS 171 the perfect tool for thinning work, in particular over long periods of time.

Both saws are designed for ease of use: each features STIHL’s ErgoStart system to make starting particularly easy, especially when cold; a multifunction handle with a rubberized grip to reduce vibration; and a preseparation air filtration system with long filter service life to keep you working efficiently without interruption. Both saws also come standard with an adjustable oil pump to regulate flow according to application and user preference, as well as an anti-vibration system that reduces vibrations at the handles by up to 20 percent compared to STIHL models without anti-vibration technology.

STIHL MS 250 vs MS 171|Sound power level

Sound power level of the MS 171 is 5 dB(A) higher than that of the MS 250, which means that the MS 171 is slightly louder than the MS 250.

The MS 250 is a professional-grade chainsaw designed for heavy-duty use by landowners and farmers. The MS 171 C-BE has similar features, but also includes some additional features such as the STIHL Easy2Start™ system, making it easier than ever to fire up your chainsaw. Aside from that, the two models are comparable in terms of power, technology, and weight.

Both models have 2-MIX engines that provide efficient fuel consumption and lower emissions compared to conventional 2-stroke engines. These engines also reduce wear and tear on the engine itself due to less friction, resulting in longer service life and longer periods between servicing. Both saws also feature anti-vibration technology to make them more ergonomic for users by reducing strain on muscles and joints during extended periods of use.

The STIHL MS 250 and the STIHL MS 171 are both powerful chainsaws, capable of felling medium to large trees. The two chainsaws are identical in terms of design, size and weight. The only difference between the two models is that the STIHL MS 171 is a newer version with an improved engine and other technical upgrades.

Due to these upgrades, the STIHL MS 171 emits slightly less sound than the MS 250.

STIHL MS 250 vs MS 171|Vibration level left/right

The MS 250 features an anti-vibration system that reduces vibration levels to the operator, which in turn reduces operator fatigue. This feature makes it ideal for those who want a heavy duty chainsaw that can be used for extended periods of time.

On the other hand, the MS 171 does not feature this anti-vibration system, making it less comfortable for use during long periods of work. Fuel Efficiency & Performance The MS 250 uses a 2-MIX engine which provides a greater fuel efficiency than conventional 2-stroke engines. The result is reduced emissions and up to 20% less fuel consumption compared to other models in its lineup.

STIHL MS 250 and the MS 171 C-BE are both great chainsaws and it may be hard to determine which one is right for you. The 171 is an updated version of the 250, but they are similar in many ways. For example, both are equipped with a powerful 2-cycle engine, side-mounted chain tensioner, and excellent build quality. They have easy-to-use features that make them extremely comfortable for long periods of use and great for homeowners or landscape professionals.

STIHL MS 250 vs MS 171|Saw chain pitch

The STIHL MS 250 is a good chain–very efficient at cutting wood, and it can handle wet wood without much fuss—but it’s not the best Stihl chainsaw you can buy. The main reason why it isn’t is because of its pitch–the number of teeth per inch on the blade. Basically, when you look down the blade, you’ll see a lot of jagged teeth (the teeth are irregularly spaced). This means that when you’re trying to rip a log or cut branches, the blade will have trouble cutting properly and will end up snapping off at one of those irregular rows.

This happens because when the blade moves through a piece of wood, the firmness of its contact with the wood causes friction which stops the blade from moving through the piece smoothly. In order to prevent this from happening, STIHL designed their chains with a finer pitch–a much smaller number of teeth per inch. The result is that when you’re cutting with these chains, there are no points where teeth are being pinched together.

When it comes to tree trimming and clearing, there are two of the most popular saws used on our property: MS 250 and MS 171. Both are equipped with a rip fence, adjustable chain pitch, and dual-action chain brake. The differences between each can be difficult to tell at a glance. 

STIHL MS 250 vs MS 171|STIHL Oilomatic saw chain type

The MS 250 uses STIHL Oilomatic Picco Micro 3 (PM3) chains, which feature a narrow kerf design for high performance but lower cutting resistance than other chains. The type of chain used in each saw determines how much cutting power it has and how long it will last before needing replacement. 

With a long list of specifications and features that make these two chainsaws so similar, it may be difficult to choose between them. The following is a list of the most important differences between the STIHL MS 250 and MS 171. 

Both models have a power rating of 2.6 hp, which means they can easily handle cutting through large trees or logs. They both use an air-cooled engine, which means they are not prone to overheating and can cut through much thicker material than other models would be able to handle. In addition to this, both models feature a 35cc engine, which means they can handle much higher speeds than their smaller counterparts.

STIHL MS 250 vs MS 171|which is more better

The main difference between the STIHL MS 250 and 171 chainsaws is that the 171 uses a specially-developed cutting attachment system. This means you have to use STIHL cutting attachments with the MS 171, but you can use any brand of cutting attachment with the MS 250. The other difference between these saws is horsepower: The MS 250 has more horsepower than the MS 171.

Other than that, these two chainsaws are identical. Both of these machines are ideal for homeowners who need a lightweight chainsaw for small jobs around their property. The STIHL MS 250 and 171 are both compact, powerful, and easy to start. These saws are gas-powered, which means they’re easier to start than electric saws because they don’t require an extension cord or outlet to be nearby. They also have a lower minimum RPM than electric motors, so they don’t bog down as easily when working through tough materials like wet wood or very long logs.

STIHL recommends that newer users choose an electric saw over a gas saw because it’s safer and easier to operate, but there’s no denying that gas chainsaws give you more power and versatility.
