This motor isn't just about raw power—it's about intelligent, controlled power delivery that adapts to your driving style and track conditions. If you're shopping for a brushless RC motor in the UK and want something that performs consistently, runs cool and gives you the competitive edge, this is the motor for you.

The XeRun 4274SD combines competitive-grade performance with practical features like excellent dustproof construction and adjustable timing to help you fine-tune your vehicle's handling. When paired with compatible Hobbywing ESCs, you get access to advanced features like sensored mode and Turbo Timing, which can increase maximum speed by up to 50% and deliver maximum power instantly when you need it most.

Key Features

• Turbo Timing Technology — When used with Hobbywing XeRun XR8 series ESCs, this motor activates Turbo Timing technology that was originally developed and proven successful in 1/10 on-road racing competition. This feature allows the motor to release maximum power instantly and promote maximum speed by up to 50%, giving you a significant performance advantage over competitors using standard motors.
• Pure Sensored Operation — Built-in Hall sensor chip enables the motor to work in pure sensored mode at all times when paired with compatible Hobbywing XeRun XR8 series ESCs. Sensored operation provides superior handling feel, better torque delivery, and more precise control compared to sensorless alternatives, which is crucial for competitive driving and complex track layouts.
• Adjustable Mechanical Turbo Timing — The mechanical turbo timing can be precisely adjusted between 20-40° in both clockwise and counter-clockwise directions, allowing you to calibrate the motor's power output to match your specific driving requirements, track conditions and vehicle setup. This adjustability helps optimise efficiency and reduce temperature rise by ensuring the motor is always running at peak efficiency for your chosen application.
• Optimised Motor Structure with 6% Efficiency Improvement — Compared to the previous XeRun 4268/4274 G2 generation, the G3 motor structure has been significantly optimised, resulting in approximately 6% improved efficiency. This means better power delivery, less heat generation, and extended running time between charges—critical advantages when you're pushing hard on the track or trail.
• IP5X Dustproof Rating — This off-road motor is rated IP5X for dustproof performance, which means it can handle the demanding conditions of dusty outdoor tracks, sandy terrain and rough off-road environments. The excellent dustproof performance prevents dust and debris ingress that could otherwise degrade performance or cause premature wear.
• Error-Free Hall Sensor System — The motor incorporates Hobbywing's patented error-free Hall sensor system with an independent high-speed, high-precision encoder that outputs pure rotor position signals. This design effectively avoids interference with sensor signals, ensuring the motor works stably and reliably in sensored mode without signal corruption or missed timing.
• Low Cogging Torque Design — The motor's low cogging torque means smoother acceleration, more responsive handling, and better throttle linearity. This translates to more predictable and controllable power delivery across the entire throttle range, whether you're making delicate adjustments or going flat out.
• Lightweight Construction — The 4274SD G3 design has been optimised to minimise weight compared to previous generations and competing motors. A lighter motor is highly convenient for drivers who need to maintain proper weight distribution and balance performance of their vehicle, particularly important for 1/8th trucks where centre of gravity and handling characteristics are critical.

Technical Performance

The Hobbywing XeRun 4274SD 2250KV Black G3 is a 1/8th scale brushless outrunner motor with a 2250KV rating that delivers impressive performance across a wide range of 1/8th off-road applications including monster trucks, short course trucks (SCTs), buggies, trucks and touring cars. The motor is designed to work seamlessly with the Hobbywing XeRun XR8 Plus ESC (150A capable, compatible with 2-6S LiPo or 6-18 cell NiMH batteries), which is the recommended pairing for unlocking all advanced features. The G3 generation benefits from significantly refined engineering, with structural optimisations throughout that result in a 6% efficiency improvement over previous G2 models. This efficiency gain is not merely a technical specification—it directly translates to cooler running temperatures, meaning less thermal stress on components and more consistent performance throughout a day of driving. The mechanical turbo timing adjustment system (20-40° range, adjustable in both directions) gives drivers unprecedented control over power characteristics, allowing fine-tuning to match everything from high-grip asphalt surfaces to loose, dusty off-road tracks. The IP5X dustproof rating provides genuine protection against the abrasive environments typical of UK off-road RC tracks, whilst the low-cogging-torque design ensures smooth, responsive power delivery from the moment you touch the throttle. Built with brushless construction for reliability, minimal maintenance and outstanding longevity, this is a motor that will deliver consistent performance race after race and bash after bash.
