Hobbywing XeRun 4274SD G3 2250KV Sensored Brushless Motor for 1/8 RC Monster Truck & Truggy

Hobbywing XeRun 4274SD G3 2250KV Sensored Brushless Motor

If you're running a 1/8 monster truck or truggy and need more low-end torque than the 4268 can deliver, the 4274SD G3 is the right call. The longer 74mm stator gives it more grunt where it counts — out of corners and over rough terrain — while the IP5X dustproof rating and 6% efficiency gain over the G2 keep it running cool and clean all day.

Key Features

• ROAR Approved – Competition legal for sanctioned racing events
• IP5X Dustproof – Sealed design rated IP5X; one of only three motors in the XeRun G3 lineup with this rating (alongside 4268-1900KV and 4268-2200KV)
• Full Sensored Mode – Built-in integrated circuit automatically identifies the sensor unit when paired with Hobbywing XR8 series ESCs — no manual setup needed
• Turbo Timing Technology – Supported when paired with XR8 series ESCs; up to 48° turbo when used with XR8 Pro G2 ESC
• 6% More Efficient than G2 – Optimized internal structure reduces heat buildup and lowers operating temperature
• Patented Staggered Pole Rotor – 4-pole-8-magnet design with low cogging for smooth power delivery and better corner control
• Adjustable Mechanical Timing – 20–40° in both directions (CW/CCW) for flexible power tuning
• Advanced Hall Sensor System – Separate magnetic ring isolates the Hall sensor from external interference for clean, error-free signal
• 7075 Aluminum CNC Stator Case – Single-piece precision machined; silicone O-ring seal at sensor port
• Gold-plated Solder Tabs – U-shaped/90° curved copper tabs with low internal resistance for easy wiring
• Premium Materials – Double insulated windings (240°C rated), high-intensity adhesive (340°C), NMB Japan bearings

4274SD G3 vs 4268SD G3 — Which One?

• 4274SD G3 (2250KV) – Longer 74mm stator, more torque, better for monster truck and truggy where low-end power matters most
• 4268SD G3 (1900–2800KV) – Shorter 68mm stator, higher KV options available, better for buggy, SCT, and on-road speed builds

Compatible Applications

• 1/8 monster truck and truggy – primary application
• 1/8 SCT, buggy, and truck
• 1/8 touring car
• 1/8 off-road recreational and competition use
• Best matched with Hobbywing XeRun XR8 Pro G3 ESC

What's Included

• Hobbywing XeRun 4274SD G3 2250KV brushless motor
• Factory accessories

Important: Do not run the motor without load for extended periods. Stop use if motor shell temperature exceeds 100°C/212°F. Follow A-A, B-B, C-C wiring order when connecting to ESC. Never hit full throttle before installing the pinion.

The XeRun 4274SD G3 pairs with Hobbywing XR8 series ESCs for full sensored operation — the built-in circuit identifies the sensor unit automatically for smoother, more precise throttle control. Turbo Timing Technology is supported when paired with compatible Hobbywing XeRun XR8 series ESCs, unlocking maximum power output for competition use. The adjustable mechanical timing ring allows CW/CCW adjustment from 20° to 40°, letting you tune power delivery to match your track and driving style. The optimized finned aluminum can improves efficiency by 6% or more over the G2, reducing heat buildup so the 4274SD G3 stays cooler during long competition runs. The advanced Hall sensor system uses a separate magnetic ring to isolate the sensor from external interference, delivering a clean and accurate rotor position signal. IP5X dustproof protection keeps debris out of the motor internals — the 4274SD G3 2250KV is one of only three XeRun G3 motors to carry this rating, making it ideal for off-road monster truck and truggy use. The 42×74mm finned aluminum housing keeps the 4274SD G3 compact and well-cooled, with easy installation into standard 1/8 scale motor mounts. The patented 4-pole-8-magnet staggered pole rotor minimizes cogging for smooth, predictable power delivery — especially important for monster truck and truggy applications where low-speed control matters. Built from a single piece of 7075 aluminum CNC-machined stator case with gold-plated U-shaped solder tabs for A/B/C phase wiring and a silicone O-ring seal at the sensor port for long-term reliability. The 4274SD G3 2250KV is the dedicated off-road monster truck and truggy option in the XeRun G3 lineup, complementing the 4268SD G3 range for buggy and on-road applications.
