Key Features
- 17 Teeth Design — This pinion gear features 17 teeth, providing a specific gear ratio that works in harmony with your Losi Mini JRX2's spur gear to determine overall drivetrain efficiency, acceleration characteristics and top speed potential. The tooth count is crucial to the performance envelope of your buggy.
- 0.5 Module Pitch — The 0.5M module pitch specification ensures this pinion gear meshes perfectly with compatible Losi components and spur gears designed to the same standard. Module pitch is a critical measurement in gear compatibility, and this standard pitch is what the Mini JRX2 requires for optimal drivetrain function.
- 2mm Shaft Bore — The 2mm shaft diameter fits precisely onto the motor shaft of your Losi Mini JRX2, ensuring a secure connection that transmits power reliably from the motor to the drivetrain without slipping or wobbling during acceleration and cornering.
- Genuine Losi Component — As an official Losi part manufactured to original specifications, this pinion gear guarantees authentic quality, durability and performance compatibility. Using genuine Losi parts protects your investment in your RC buggy and ensures long-term reliability.
- Brushed Motor Compatibility — Specifically designed for the brushed motor setup in the Losi 1/16 Mini JRX2, this gear is optimised for the torque characteristics and RPM range of brushed RC motors, delivering smooth power delivery and efficient drivetrain engagement.
- Affordable Replacement Option — Replacement and upgrade gears wear over time with regular use, and having affordable genuine spares available means you can keep your RC buggy running at peak performance without expensive downtime or waiting for parts to arrive from overseas.
Technical Performance
This pinion gear represents precision engineering at the small scale, manufactured to exacting tolerances that ensure smooth meshing with the spur gear and reliable power transmission from your brushed motor to the wheels. The 17-tooth configuration, combined with the 0.5 module pitch standard, creates a balanced gear ratio suitable for the responsive handling characteristics expected from a 1/16 scale buggy. The 2mm shaft bore is precisely machined to fit the motor shaft of the Losi Mini JRX2 without any play, ensuring that every ounce of motor torque is transferred efficiently to propel your RC car. The gear is engineered from durable materials selected to withstand the demands of RC racing and recreational bashing, maintaining tooth profile integrity even under sustained use on grass, dirt and track surfaces across the UK. For brushed motor setups, this gear ratio provides an excellent balance between acceleration and top speed, making it suitable for both competitive racing and casual driving enjoyment.

Frequently Asked Questions
- Is this pinion gear compatible with my Losi Mini JRX2? — Yes, this gear is specifically engineered for the Losi 1/16 Mini JRX2 Brushed 2WD Buggy (model C-LOS01020T3). The 2mm shaft bore and 0.5M module pitch ensure perfect compatibility with this vehicle.
- What does the 17T specification mean? — The 17T designation indicates this pinion gear has 17 teeth. Combined with your spur gear tooth count, this determines your overall gear ratio, which affects acceleration, top speed and efficiency of your RC buggy's drivetrain.
- Why would I need to replace this gear? — Pinion gears experience wear over time as they mesh continuously with the spur gear during driving. If you notice slipping, grinding noises or reduced acceleration, a worn pinion gear may be the cause. Additionally, changing the pinion tooth count allows you to adjust your overall gear ratio for different driving conditions or performance goals.
- What is module pitch and why does 0.5M matter? — Module pitch (or modulus) is an international standard measurement for gear teeth spacing. The 0.5M specification means this gear is engineered to mesh perfectly with other 0.5M components on your Mini JRX2. Using incompatible module pitches will result in poor meshing, noise and drivetrain problems.
- Can I use this to adjust my RC buggy's performance? — Yes. By choosing different pinion tooth counts, you can change your overall gear ratio. A lower tooth count (fewer teeth) increases top speed but reduces acceleration, while higher tooth counts improve acceleration at the expense of top speed. The 17T option provides a balanced setup for mixed driving.
- Is this a genuine Losi part? — Yes, this is an official Losi component manufactured to original specifications. The part number Z-LOS212025 is the genuine Losi designation, ensuring authentic quality and perfect compatibility with your Mini JRX2.
