The STIHL MS 500i is the world's first production chainsaw with electronically controlled fuel injection (STIHL Injection), delivering a 79.2cc engine producing 5.0 kW (6.8 hp) at just 6.3 kg powerhead weight — a power-to-weight ratio of 1.24 kg/kW. Designed for professional forestry contractors and tree surgeons tackling felling, bucking and delimbing, it adapts fuel delivery and ignition timing automatically to environmental conditions for consistent performance at any altitude or temperature. In stock at Gustharts as an authorised STIHL dealer, with free UK delivery over £75.
Key Features
- STIHL Injection (i) – Electronically controlled fuel metering, the first in any production chainsaw. Instant throttle response and consistent power regardless of temperature, altitude or fuel variance.
- 5.0 kW / 6.8 hp Engine – 79.2cc displacement delivering an outstanding 1.24 kg/kW power-to-weight ratio.
- 6.3 kg Powerhead Weight – Lightweight for its class; reduces fatigue during extended felling and bucking operations.
- Bar Compatibility: 40–90 cm (16–36") – Suited to a wide range of timber diameters from processing to large-scale felling.
- HD2 Air Filter – Pre-separation and oil/water-repellent material for extended engine protection in dusty forestry environments.
- Ematic Lubrication System – Precise oil delivery reduces bar oil consumption by up to 50%.
- ElastoStart & Anti-Vibration System – Reduced pull resistance on start; advanced vibration dampening for all-day comfort.
- Tool-Free Fuel and Oil Caps – Fast refuelling without tools in the field.
- Side-Mounted Chain Tensioning – Quick chain adjustments on site.
Technical Specifications
Why Choose the STIHL MS 500i?
The MS 500i sits in the upper tier of the STIHL professional forestry range — above the MS 462 C-M and MS 261 C-M in both displacement and output. Its fuel injection system is what sets it apart from every other production chainsaw: instant throttle response with no flat spots, reliable cold-weather starting, and consistent power at altitude. For forestry contractors working long shifts across varied timber and terrain, the combination of 5.0 kW output at 6.3 kg powerhead weight and the 40–90 cm bar range makes it exceptionally versatile. The MS 500i W variant adds heated handles for cold-climate operations.

- Forestry PPE – chainsaw trousers, helmets, gloves and boots for compliant felling work
FAQs
What makes the MS 500i different from a standard carburettor chainsaw?
The MS 500i uses electronically controlled fuel injection rather than a carburettor. This delivers instant throttle response, consistent power across all temperatures and altitudes, and removes the need for carburettor adjustment in the field.
What is the difference between the MS 500i and the MS 500i W?
The MS 500i W is identical in engine specification but adds electrically heated handles for cold-weather operation. Both share the same 79.2cc fuel-injected engine and 5.0 kW output.
What bar lengths are compatible with the MS 500i?
STIHL recommend 40–90 cm (16–36") guide bars. The MS 500i uses ⅜" RS3 chain. Gustharts stocks compatible bars and chains.
How does the MS 500i compare to the MS 462 C-M?
The MS 500i is larger at 79.2cc vs 72.2cc, produces more power (5.0 kW vs 4.4 kW), and adds fuel injection for instant response. The MS 462 C-M is lighter at 6 kg vs 6.3 kg and better suited where weight is the primary concern.
Is the MS 500i suitable for chainsaw milling?
Yes — its wide bar compatibility (up to 90 cm) and high torque output make it well suited to Alaskan mill setups for processing large-diameter logs.
