Gears & Gear Sets

Gears and gear sets determine how engine power is transferred through the transmission and ultimately to the drive wheel. Primary and secondary gears work together to establish the final drive ratio, affecting acceleration, top speed, and overall responsiveness. Over time, gears may wear, chip, or develop excessive backlash, leading to noise, vibration, or poor power transfer. This category includes replacement gear sets commonly used in GY6 50cc–150cc scooters and small ATVs and go-karts from brands like TaoTao, Roketa, Jonway, and other similar manufacturers. Upgrading or replacing gears can improve durability, restore proper drivetrain performance, or alter gearing to suit specific riding conditions.

This category may include:

• Primary and secondary transmission gear sets
• Output shaft gears and internal drivetrain components
• Gear sets for GY6 scooters and similar small engines
• Replacement parts suitable for ATVs, dirt bikes, and go-karts
• Components compatible with TaoTao, Roketa, Jonway, Peace Sports, and related brands

Additional notes about this collection:

• Helps resolve drivetrain noise, poor acceleration, or gear wear issues
• Allows tuning of final drive ratios for more torque or higher top speed
• Useful during transmission rebuilds or when upgrading drivetrain durability
• Designed for accurate fitment when matched to engine type and gear ratio specifications
