As part of the new chainsaw upgrades, the MS 261 C-M will now come fitted with .325” RS PRO and the MS 271 with the RM3 PRO saw chain as standard. The 1.3mm gauge chain, which matches the 1.3mm bar groove, offers up to 20% greater cutting performance when compared to .325 RS saw chain [with .063[1/6mm] Gauge]. The faster cutting comes from the thickness of the cutter tooth that is reduced from 7.7mm to 6.8mm, meaning less wood is removed from the cut for more efficiency.
This is the RS PRO version of the chain.
