STIHL MS 231 vs MS 251|Engine Displacement

The most obvious difference between the two chainsaws is their engine displacement. The STIHL MS 251 C-BE has a larger engine at 50.2cc. In contrast, the STIHL MS 231 C-BE only has an engine displacement of 44.3cc. In addition, the STIHL MS 251 C-BE has a larger fuel tank at 15% more capacity than that of the STIHL MS 231 C-BE (at 18.3 fl oz vs 15.9 fl oz).

Also, both chainsaws have different cutting bars for different uses: The STIHL MS 251 C-BE chain saw comes with a 16 inch Bar and Chain – ideal for cutting through medium sized branches and logs up to 24 inches in diameter (also available in 14 inch, 18 inch, 20 inch and 24 inch bar lengths) The STIHL MS 231 C-BE chain saw also comes with a 16 inch Bar and Chain – ideal for.

When you need a chainsaw that’s lightweight, reliable and easy to start, the STIHL MS 231 and MS 251 are excellent choices. Both of these models have the QuickStop® inertia chain brake for added safety, as well as Master Control Levers™ for easy operation and comfortable handling. Every STIHL saw is built to be durable and dependable, so we’ll focus here on what makes these two mid-range models unique.

STIHL MS 231 vs MS 251|Power output

The first difference between the two chainsaws is their power output. The MS 231 has a 3.1 horsepower output, while the MS 251 has a slightly higher 3.2 horsepower output. The two models are otherwise nearly identical in weight and dimensions, so this difference would be apparent only if one was used next to the other.

There may be some small improvements in performance due to this discrepancy, but it is unlikely to be noticeable without rigorous testing or scientific analysis of the tools’ capabilities. Bar Length The bar length of the Stihl chainsaws also varies slightly. The MS 231 has a 16-inch bar length, while the MS 251 has an 18-inch bar length.

One of the main differences between the two chainsaws is the power output. The MS 231 gives out 2.4 kW at 9,500 RPM. On the other hand, the MS 251 gives out 2.6 kW at 9,500 RPM. That extra 0.2 kW may not seem like a lot but it means that when you are handling work you could get it done faster with the MS 251 than the MS 231. Another difference is the weight of these two chainsaws. The MS 231 weighs in at 10 pounds while the MS 251 weighs in at 11 pounds.

STIHL MS 231 vs MS 251|Weight

Stihl MS 231 vs. Stihl MS 251: Weight Looking at the specs of the MS 231 and MS 251, there is no noticeable difference in weight. Both saws weigh 11.3 pounds. There are a couple of things that may account for this similarity in weight.

First, the MS 251 and MS 231 have identical engine displacements. Second, they use similar components, such as crankshaft types and mufflers. Both models are relatively lightweight compared to other chainsaws on the market. However, some homeowners may find these saws too heavy for extended use.

Fortunately, STIHL offers both models with small features that can make them more comfortable to use for longer periods of time. Their top handles can be adjusted for varying heights and postures, and an ErgoStart system eases starting for all users.

Another consideration when choosing between the Stihl MS 231 vs. Stihl MS 251 involves the type of cutting tasks you need to perform. If you plan on cutting large logs or felling trees frequently, either model will work well for you. However, if you only need to cut smaller pieces of wood or occasional limbs from trees, it may be worth looking into a lighter saw that offers similar performance characteristics.

MS 231 Vs MS 251

STIHL MS 231 vs MS 251|Power-to-weight ratio

We compare the STIHL MS 231 vs MS 251 to help you decide which is right for you. Both the MS 231 and the MS 251 are petrol powered chainsaws with 2-MIX engines, both have side access chain tensioning, and both feature tool free fuel caps.

The main differences are in the power-to-weight ratio and anti-vibration systems. The MS 231 has lower engine displacement (31.8cc compared to 50.2cc) than the MS 251, which means it will be less powerful (1.6kW vs 2.3kW), but it’s also lighter weight (4.1kg without fuel and cutting equipment compared to 4.7kg). The lower engine displacement is great for users who want a lighter weight saw that’s still powerful enough for most jobs around their property, especially if they don’t necessarily need to cut through large amounts of wood per day.

STIHL MS 231 vs MS 251|Sound pressure level

The MS 251 is one of our most popular chainsaws. Like many of the STIHL models, this saw has a 2-MIX engine which allows for increased efficiency and lower fuel consumption. One of the main differences between the MS 251 and the MS 231 is that the MS 251 has an additional 10% more power than its predecessor.

Another difference between the two saws is the sound pressure level. The MS 231 has a sound pressure level of 111 dB(A), while the MS 251 has a sound pressure level of 98 dB(A). The sound pressure level refers to how much noise is made during the operation.  A lower number indicates that less noise is being produced by your chainsaw, making it easier on your hearing. 

STIHL MS 231 vs MS 251|Sound power level

One of the most popular Stihl saws is the MS 251 chainsaw, which is in the same series as the MS 231. While both chainsaws are known for their power and efficiency, there are some differences between them.

Perhaps the most notable difference is that the MS 251 has a larger engine than its counterpart (50.2 cm3 compared to 45 cm3). The larger engine allows for more power output, but it also means that the MS 251 has a higher fuel consumption—about .88 kg/h higher than that of the smaller model.

Another difference between these two chainsaws is found in their oil consumption: the MS 231 uses about .17 l/h less oil than its larger counterpart. These differences may seem small, but they’re significant enough to have an impact on fuel and oil consumption if you plan on using either of these tools for extended periods of time.

Both chainsaws have similar bar lengths and weigh approximately the same, which means they’re light enough to be handled with ease but still effective at cutting through wood of varying thicknesses. The MS 231 and MS 281 chainsaws also share other similarities such as a manual fuel pump, an automatic chain lubrication system, a side-chain tensioning system and a sound.
