Which chainsaw sizes should a distributor stock? 25cc to…

Short answerMost dealers cover their market with three chainsaw classes: a 25–45cc saw for pruning and homeowners, a 52–58cc saw with an 18–20 inch bar for farms and firewood, and a 72–92cc saw for felling and professional logging. A 105cc saw only makes sense where large hardwood is milled or felled every day.

Why does displacement matter more than the box says?

Displacement, measured in cubic centimetres (cc), sets how much power the engine can deliver to the chain. Power determines the longest bar the saw can pull without bogging down in the cut. A 25cc saw is comfortable with a 10–12 inch bar, while a 92cc saw can pull 36 inches or more. Selling a small saw with a long bar is the most common cause of warranty complaints about "weak" engines.

What is each class used for?

Class	Typical bar	Main buyers	Typical work
25–45cc	10–18 in	Homeowners, orchards	Pruning, limbing, small firewood
52–58cc	18–24 in	Farmers, rural dealers	Firewood, storm clean-up, felling small trees
72cc	20–28 in	Contractors, forestry	Felling and bucking medium timber
92cc	20–42 in	Logging crews	Large-diameter hardwood
105cc	36–42 in	Mills, heavy logging	Milling and the largest trees

In our own range those classes map to the NT2510 and NT4520 (light), the NT5800 and NT5853 platforms (mid), and the 72cc, 92cc and 105cc professional saws.

Which class should carry most of your stock?

For farm and rural markets, the 52–58cc class usually carries the largest share of orders, because one saw can handle firewood, fencing and occasional felling. Light saws sell in volume where gardens and fruit farms dominate. Large saws sell in smaller numbers but at higher value, and buyers expect spare chains, bars and sprockets to be available locally.

How do I match bars and chains to each saw?

Agree three things with your supplier before you order: bar length, chain pitch and chain gauge. Mid-size saws commonly use .325 inch or 3/8 inch pitch; large saws use 3/8 inch or .404 inch. Keep pitch consistent across your range where you can, so one stock of chain fits several models.

What should I check on a sample saw?

Cold start: it should start within a few pulls after the choke routine in the manual.
Idle: the chain must not move at idle.
Chain brake: test it at full throttle on a sample.
Oiler: hold the tip over a light surface at high revs and look for an oil line.
Vibration: compare handles after five minutes of cutting.
