Description:

The wrap-handle design of the MS 500i R is engineered to meet the specific needs of forestry personnel and tree service professionals. The revolutionary MS 500i R was the first chainsaw on the worldwide market to feature a wrap-handle design combined with electronically controlled fuel injection.

With its outstanding power-to-weight ratio and ergonomic construction, this saw is a versatile tool for felling, bucking, and delimbing operations in multiple working positions. A blend of leading-edge innovation and world-class STIHL engineering, the MS 500i R delivers uncompromising performance and rapid acceleration thanks to its unique fuel injection system—making it a nearly unparalleled addition to the legendary lineup of STIHL® equipment.
