This is an essential feature if you work in a dusty environment as it ensures that your machine will continue running smoothly without any problems. The chain brake system on this saw is automatic, meaning that it starts working as soon as the trigger is released so you don’t have to worry about wasting any time getting it ready again after each cut.

The chain brake also prevents kickback which can be very dangerous if not dealt with immediately. The MS 251 C-BE comes with an 18-inch bar and chain which allow you to cut through thick branches and even small trees with ease — something that would be impossible with a smaller bar length!

STIHL MS 231 C-BE vs MS 251 C-BE|Engine Displacement

The STIHL MS 231 C-BE and the STIHL MS 251 C-BE are both chainsaws from the manufacturer that have been on the market for quite some time now. Both of these models are designed to provide users with a wide array of cutting options, including a powerful engine that delivers plenty of power and torque to cut through even the toughest of materials.

The STIHL MS 231 C-BE features an engine displacement of 90 cc while the STIHL MS 251 C-BE features an engine displacement of 110 cc. While this may not seem like much of a difference in terms of performance, there are some important things to consider when comparing these two models side by side: The larger displacement engine on the STIHL MS 251 C-BE provides more power than its smaller counterpart.

The engine displacement of a chainsaw is the total amount of air and fuel that can enter the engine per cycle. It’s measured in cubic centimeters (CC) or cubic inches (CI). The bigger the number, the more powerful the saw will be. An engine displacement of 43 CC means it has an air/fuel mixture that’s 43 times larger than what a car engine can handle.

The STIHL MS 231 C-BE and STIHL MS 251 C-BE both utilize 2 stroke engines as their primary power source. 2 stroke engines are simpler than 4 stroke engines because they don’t have to go through all four cycles of operation — intake, compression, power and exhaust — in order to complete one cycle of operation like 4 stroke engines do.

STIHL MS 231 C-BE vs MS 251 C-BE|Power output

The MS 251 C-BE produces an additional 0.4 horsepower over its counterpart, making it a more powerful chainsaw. This extra horsepower is especially noticeable when cutting through hardwood, like oak and maple. It also increases the overall speed of the chain, meaning that it’s able to cut faster and deeper.

MS 231 C-BE has a fuel consumption rate of 376 grams per kilowatt hour, while the MS 251 C-BE burns 392 grams per kilowatt hour—that’s an increase of 16 grams. Even if you use your chainsaw sparingly, this is enough to make a noticeable difference in how much gas you need to get through the year. Another major difference is in their design features. The MS 231 C-BE has an overall length of only 27 inches, which makes it ideal for people who work alone and need to be able to maneuver their chainsaws around obstacles easily.

STIHL MS 231 C-BE vs MS 251 C-BE|Weight

The weight of these two saws is very similar, making them both lightweight and easy to maneuver for their class of saw. This means that both are capable of handling a wide range of tasks, from light cutting to more demanding work. Both models have an Easy2Start system that makes starting your STIHL chainsaw easy and convenient with just one pull, no matter what the weather conditions may be.

The STIHL MS 231 C-BE chain saw with Easy2Start technology is easy to use and ideal for cutting firewood or felling trees. It features a low-emission, fuel-efficient engine, and an advanced anti-vibration system for operator comfort. 

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

If you’re looking for a gas-powered chainsaw that’s lightweight and easy to carry, the MS 231 C-BE is an excellent choice. The STIHL MS 251 C-BE, on the other hand, offers even more power in a comparable package. The MS 251 C-BE weighs 3 pounds more than the MS 231 C-BE and has a slightly longer bar length (14 inches).

It also boasts a higher power-to-weight ratio than its smaller sibling, meaning it can outperform it in most situations. In addition to being heavier and longer, the MS 251 C-BE also has two more teeth per inch on its chain — which means it can cut through wood faster than the MS 231 C-BE.

STIHL MS 231 C-BE vs MS 251 C-BE|Sound pressure level

Another difference between these two models is their sound pressure level (SPL). This is measured in decibels (dB) and expressed as a single number rather than as a range like other noise ratings such as dB(A). The SPL rating indicates how much noise each machine produces when operating at full throttle.

MS 251 C-BE is a powerful, compact chainsaw with a 3.2 kW engine, making it ideal for cutting hard and softwood trees. It features an anti-vibration system that reduces vibration by up to 50%.
