• Optional Performance Packs: Lighter sprint-focused and higher-capacity race options planned for extended sessions and competition use

Controller & Electronics:
Advanced high-amperage controller platform developed specifically for the 902’s power level, paired with Bonnell’s next-generation production electronics for precise, repeatable performance.

Key Technology:

• Pulse Control System: Intelligent motor management delivering smooth, predictable power across traction, lean angle, and speed

• Electronic Clutch & Regenerative Braking: Rider-adjustable trigger control for simulated clutch feel or variable engine braking

Full-Size Geometry:

• 21” Front / 18” Rear wheels using full motocross-standard sizing

• Custom Sirris suspension with long-travel race tuning (approximately 285 mm front and rear), delivering high-speed stability, big-hit control, and true MX confidence

Battery & Charging

Battery Options: Available in multiple configurations designed around full-size race performance.

• Core Battery: High-capacity 6.6 kWh pack engineered for sustained output and aggressive riding

• Optional Performance Packs: Lighter sprint-focused and higher-capacity race options planned for riders prioritizing reduced weight or extended sessions

Swappable Design:
Modular battery system designed for quick pack changes, allowing riders to swap batteries efficiently between motos, practice sessions, or race laps.

Chassis Integration:
The battery is centrally mounted within the forged aluminum frame to maintain a low center of gravity and balanced weight distribution. This integration enhances stability at speed and keeps handling predictable under hard acceleration and braking.

Charging Capability:
Designed to support high-output charging systems appropriate for its capacity, reducing downtime compared to entry-level charging solutions and keeping the bike ready for repeated hard sessions.

Performance Efficiency:
Purpose-built to support the 902’s high-output powertrain, the battery system delivers consistent voltage under heavy load, ensuring strong sustained torque and reliable performance well beyond standard e-moto platforms.

Wheels & Tires

Stock Moto Wheelset:
The Bonnell 902 runs a full-size 21” front / 18” rear wheel configuration, giving riders access to the complete range of professional motocross and off-road tire options.

Tire Compatibility:
Designed around full-scale moto tire sizing, the 902 supports standard MX tire profiles for optimal traction, durability, and predictable handling across track, trail, and high-speed terrain.

Custom SIRRIS Suspension:
The chassis is paired with custom-tuned SIRRIS suspension, engineered specifically for the 21/18 wheel setup. With long-travel race tuning (approximately 285 mm front and rear), the suspension delivers stability through chop, confidence on landings, and control at speed.

Chassis Integration:
A forged aluminum frame and full-size wheelbase are designed to maintain stability during aggressive riding and high-speed operation, while keeping the bike balanced and composed under braking and acceleration.

Versatility:
With true full-size moto geometry from the factory, the Bonnell 902 requires no wheel or chassis upgrades to ride hard. It’s ready for motocross tracks, desert runs, and technical terrain straight out of the crate.

Brakes & Suspension

• Bonnell Forged Brakes – Race-grade forged braking system engineered for strong, consistent stopping power during high-speed riding and repeated hard braking.

• Oversized Brake Rotors – Large-diameter rotors designed to manage heat effectively and maintain control under aggressive riding conditions.

• Long-Travel Performance Suspension – Custom-tuned front suspension built to absorb big impacts, track smoothly through chop, and remain stable at speed.

• Balanced Rear Suspension – Precisely valved rear shock designed to keep the bike planted and predictable during hard acceleration, braking, and rough terrain.

Regenerative Braking

• Adjustable Regenerative Braking – The Bonnell 902 features rider-adjustable regen braking, allowing you to fine-tune deceleration feel and control. This system improves stability under braking, enhances efficiency, and delivers smoother transitions during aggressive riding and high-speed entries.
