Key Features
- 16-Tooth Configuration — The 16-tooth count represents a carefully balanced gear ratio option within the HoBao ecosystem, allowing you to fine-tune your buggy's acceleration, top speed and overall performance characteristics by swapping between different tooth counts to suit your driving style, track conditions and racing requirements.
- MOD 1 Specification — This gear adheres to the MOD 1 (Module 1) standard, which is the industry-standard gear profile used across HoBao's Hyper range, ensuring perfect compatibility and smooth engagement with your vehicle's transmission system without binding, slipping or premature wear.
- 5mm Bore Diameter — The precisely machined 5mm bore provides a snug, secure fit on standard 1/8-scale motor shafts, eliminating play and vibration that could otherwise compromise efficiency and reliability during high-speed running or competitive racing situations.
- Genuine HoBao Component — As an original equipment manufacturer (OEM) part, this pinion gear is manufactured to HoBao's exacting specifications and quality standards, ensuring perfect compatibility with all supported vehicle models and delivering the performance characteristics HoBao engineers intended.
- Universal Compatibility — This pinion gear is compatible with multiple models in the HoBao Hyper lineup, including the Hyper SS 1/8th Buggy Electric Roller, Hyper SSe 1/8 RTR Buggy variants, and the highly respected Hyper VS2 series in both roller and RTR configurations, making it an excellent spare part for collectors and racers running multiple vehicles.

Technical Performance
HoBao has built an enviable reputation in the RC racing community for manufacturing hardwearing, precision-engineered components, and this pinion gear exemplifies that commitment to quality and performance. The gear is manufactured to MOD 1 specifications, which is the recognised standard for 1/8-scale RC buggies, ensuring seamless compatibility with spur gears and other drivetrain components across the Hyper range. The 5mm bore is precision-drilled to exacting tolerances, providing a secure fit that minimises run-out and vibration even under the intense stresses of competitive racing or aggressive bashing. The 16-tooth configuration sits in the mid-range of tooth count options, offering a practical balance between acceleration response and top-end speed—ideal for drivers who want versatile performance across varied track conditions. The gear material is engineered to resist wear and deformation, ensuring consistent meshing characteristics throughout the product's operational lifespan. Whether you are upgrading from a lower tooth count for improved acceleration or stepping up from higher teeth for increased top speed, this pinion gear integrates seamlessly into your existing HoBao Hyper drivetrain, allowing you to optimise your RC buggy's performance without replacing other expensive components.

Frequently Asked Questions
- What is a pinion gear and why does my HoBao buggy need one? — A pinion gear is a small toothed wheel that meshes with a larger spur gear to transmit power from the motor to the wheels. The number of teeth on the pinion gear directly affects your buggy's gear ratio, which controls the balance between acceleration and top speed. If your current pinion gear is worn, stripped, or damaged, you will experience poor power delivery, grinding noises, or loss of efficiency. Replacing or upgrading your pinion gear is one of the simplest and most cost-effective ways to maintain or modify your RC buggy's performance.
- How do I know if I need to replace my pinion gear? — Signs that your pinion gear needs replacement include visible wear, missing or chipped teeth, a grinding noise during acceleration, inconsistent power delivery, or slipping between the pinion and spur gear. If your HoBao buggy is not performing as it should, inspecting the pinion gear is a logical first troubleshooting step. Replacement is straightforward and can be completed in minutes with basic tools.
- What is the difference between 15-tooth and 16-tooth pinion gears? — The tooth count affects your gear ratio and therefore your vehicle's performance characteristics. A 15-tooth pinion gear (fewer teeth) will provide slightly quicker acceleration and a higher top speed, whilst a 16-tooth pinion gear (one more tooth) will offer marginally better low-end torque and slightly lower top speed. The difference is subtle but noticeable on track. Most drivers will find the 16-tooth option to be a versatile, all-round choice suitable for a range of driving conditions.
- Is this part genuine HoBao? — Yes, the H89326 is an original HoBao part number and is manufactured to the exact specifications of genuine HoBao components. Purchasing genuine OEM parts ensures perfect compatibility, consistent quality and the performance characteristics HoBao engineers designed into your vehicle. Counterfeit or incorrect clone parts may fit loosely, wear quickly, or cause drivetrain damage.
- Will this pinion gear fit my HoBao buggy? — This 16T MOD 1 5mm bore pinion gear is compatible with the HoBao Hyper SS, Hyper SSe and Hyper VS2 series in both roller and RTR configurations. Check your vehicle's documentation or product page to confirm compatibility before purchase. If you are unsure, contact our RC Model Shop team and we will be happy to help you identify the correct pinion gear for your specific model.
- How often should I replace my pinion gear? — With regular maintenance and proper lubrication, a quality pinion gear can last hundreds of hours of running. However, race teams often stock multiple pinion gears in different tooth counts to optimise performance for different track layouts or weather conditions. As a general rule, inspect your pinion gear monthly and replace it whenever you notice visible damage, wear or performance degradation.
