STIHL MS 251 C-BE Vs MS 251

STIHL MS 251 C-BE is a premium, professional-grade chainsaw that is built for commercial use. It has the best power to weight ratio among all other Stihl chainsaws. The engine is made of cast iron and it has a metal plate for the crankshaft and flywheel. The bar and chain combination makes this a very powerful saw when it comes to cutting down trees or clearing land.

The engine delivers excellent power at low rpm and can easily cut through logs up to 30 inches in diameter. The only downside is that it takes some time to get used to the low rpm range, but once you have mastered it, you will have no problem cutting down any tree with this saw.

The main difference between these two models is their power source — one uses gasoline while the other uses diesel fuel. You can choose between these two models depending on your preference for fuel type. Another difference between these two models is their weight; MS 251C-BE weighs more than MS 251 because of its larger engine size which increases its overall weight by about 4 pounds (1kg).


STIHL MS 251 is a mid-range chainsaw with a powerful engine and an excellent cutting performance. It comes with a 2-year warranty and has many features that make this saw a great choice for homeowners who need a reliable tool that can handle most types of tree cutting tasks. The MS 251 is powered by an easy-starting and durable 50.2 cc engine, which delivers impressive performance in both softwood and hardwood applications.

It’s equipped with an auto return stop switch feature as well as automatic oiling system that helps to protect the engine from overheating while operating. The saw also features a chain brake mechanism to ensure safety when operating this machine at full speed. This model also has an auto return stop switch feature plus automatic oiling system that helps to protect the engine from overheating while operating with low oil levels in the reservoir tank.

STIHL MS 251 C-BE vs MS 251

Engine Displacement:

The MS 251 C-BE is the latest generation of the popular MS 251 chainsaw, incorporating a number of refinements over the original model. Like the MS 251 itself, the MS 251 C-BE is designed for demanding cutting jobs. The two models share many features, but there are also some important differences. Engine Displacement Both models boast a 50.2cc engine displacement, which translates to about two horsepower. This means that both models are capable of generating enough power to handle a variety of medium-duty tasks like cutting firewood and clearing land.

However, neither model has enough power to be used as a professional saw in logging applications. Chain Brake System The “C-BE” portion of the MS 251 C-BE’s name stands for “chain braking system.” For safety reasons, STIHL chainsaws are equipped with chain brakes that activate automatically when an object causes the chain to stop rotating suddenly. On the standard MS 251, the brake activates when your left hand presses down on a lever on top of the machine’s handlebar; this lever also houses a throttle control that allows you to adjust engine speed while you’re working.

Power output:

STIHL MS 251 C-BE is a mid-range cordless chainsaw that features a 6.3Ah battery, allowing for up to 1 hour of runtime. The MS 251 is a lower end model that houses a 4.0Ah battery and can run up to 45 minutes per charge. The 250 series chainsaws are designed for both professional and homeowner use, making them ideal for small jobs around the house or yard, such as trimming trees, pruning branches and cutting firewood. Both models are powered by a long stroke engine with an automatic oil pump system that ensures optimal lubrication at all times.

Both saws also feature an adjustable chain tensioning system that allows you to adjust the tension on your chain as needed based on wear or terrain conditions. Power output One of the biggest differences between these two saws is their power output. The MS 251 C-BE has more than double the power output of the MS 251 model at 3,000 watts compared to 1,500 watts respectively. This means it will have better cutting capability when dealing with thicker pieces of wood or heavier branches than its counterpart would be able to handle in the same time frame (45 minutes).


The STIHL MS 251 is a lightweight, two-stroke chainsaw designed for homeowners and occasional users. This saw weighs in at just under 11 pounds and features an anti-vibration system to reduce operator fatigue. The MS 251 C-BE is the same saw, but it comes with a bar and chain that are designed for commercial use. The MS 251 is powered by a 196 cc engine that produces up to 5.7 horsepower.

This provides plenty of power for most jobs around the house, including removing small trees and limbs, cutting firewood and clearing brush from your property. In this article we will take a look at some of the differences between these two versions of the MS 251 so that you can make an informed decision when deciding which one will work best for your needs.

Both of these models are great for cutting firewood, but there are some key differences between them that may help you decide which one is best for your needs.

Both the MS 251 and 251 C-BE are designed with a 2-MIX engine, which combines fuel and air in a precisely metered ratio.

Additionally, the MS 251 C-BE has a pre-separation air filtration system that can extend the life of your air filter by five times over non-filtered systems.

Sound power level:

The STIHL MS 251 C-BE and MS 251 are very similar in that they both provide the same great power, fuel efficiency, and performance. The main difference between the two is that the MS 251 C-BE has a Quick Chain Adjuster. This makes it easy to tighten your chain without tools.

Both of these chainsaws have a professional cutting system that allows you to work faster and safer with less effort required from you. There’s also a side access chain tensioner that’s easy to use and makes adjustments quick and simple so you don’t have to waste time keeping your chain tight all day long or risk injury by trying to do it manually with tools while cutting wood at high speeds.

Vibration level left/right:

The STIHL MS 251 C-BE is a chainsaw that has been built for the professional user. It is a powerful and well balanced machine with a strong cutting ability, but it does have some issues with vibration during use.

Saw chain pitch:

STIHL MS 251 C-BE is the latest addition to the STIHL line of chainsaws. It claims to be the most powerful, most durable and most dependable chainsaw available in India. On the other hand, the MS 251 has been around for a while now, but it still remains one of the best sellers in its category.

The STIHL MS 251 C-BE comes with a 3/8″ pitch chain, whereas its predecessor comes with a 1/2″ pitch chain. The latter is slightly more common among domestic users as well as professionals who prefer working around their homes or on smaller job sites. However, when it comes to cutting bigger logs or branches from trees or bushes, it gets difficult to use such small pitches because they tend to get stuck in the wood.

STIHL Oilomatic saw chain type:

The STIHL MS 251 C-BE is a chain saw that belongs to the STIHL OILOMATIC® line of products. It is designed for professionals and will provide them with a powerful, smooth running machine that will last for years to come. The MS 251 C-BE offers convenience and durability in one package.

The MS 251 C-BE is equipped with an automatic oiler that ensures proper lubrication during operation. This means that you will not have to worry about the chain getting too much or too little oil, as it has been programmed to give just the right amount at all times. The MS 251 C-BE also comes with a unique cutting bar design that provides better performance than other models.

The cutting bar has been designed specifically for professional use and has a longer lifespan than other models on the market today. And because it uses fewer moving parts than other chainsaws, this model is less likely to break down while you are working. The MS 251 C-BE has been designed with comfort in mind; its handlebars can be adjusted so they fit your body perfectly, allowing you to work efficiently without straining yourself unnecessarily. In addition, its weight is light enough that even men who are smaller in stature can comfortably use this saw without.

The MS 251 C-BE features a STIHL Easy2Start™ system for effortless starting every time. It also features Soft Start, significantly reducing the amount of force needed to start the saw. Simply pull the cord and let go – the spring-action system does the rest. The STIHL MS 251 C-BE is also easy to maintain, with an excellent chain adjusting system that allows for tool-free chain adjustment.

The fuel and oil caps are designed with retention tabs to prevent loss while refueling or adding bar oil. The MS 251 C-BE has all these features, plus it is environmentally responsible thanks to a 2% reduction in fuel consumption and up to 70% reduction in exhaust emissions compared to previous models.

The MS 251 Wood Boss® is designed for rugged homeowner or landscape and farm use. It combines technology and ergonomics with a new, powerful engine and excellent fuel economy. It starts easily, even in cold weather, and its raw power tackles big jobs quickly. This high torque engine is easy on fuel, too.

The End

The MS 251 has an electric starter whereas the MS 251 C-BE relies on pull start technology instead. This means that if your battery runs out, then you won’t be able to start up your saw manually without first charging up its battery! With this in mind, we recommend getting yourself a spare battery just in case something goes wrong with your current one.
