Glixal Chinese Scooter High Performance Racing Torque Spring Clutch Springs GY6 50cc-100cc 139QMB 1P39QMB Engine (1000RPM,Blue)

Azabooti presents the Glixal high performance torque spring clutch kit for GY6 engines. Improve take-off and control with a tunable 1000 RPM blue spring and complete clutch set.

Unlock peak scooter performance with precision clutch timing and responsive take-off. This Glixal high-performance torque spring clutch kit is designed for GY6 50cc to 100cc engines (139QMB/139QMA), delivering tunable engagement through a 1000 RPM blue spring and a complete set of three clutch springs plus one torque spring. Whether you’re chasing quicker hill starts, sharper acceleration, or a balanced upgrade for everyday commuting, this kit gives you the control you want on every ride.

What makes this kit stand out is the ability to fine-tune your clutch engagement to match your riding style and terrain. The 1K springs provide a smoother, lower-RPM engagement that can help you maintain speed on flatter streets and keep RPMs in a friendly range during take-off. If you want the greatest grabbing power and faster take-off RPM for steep climbs, the 2K springs are designed to maximize grip and response. For a balanced blend of smoothness and power, the 1.5K springs offer the middle ground. Each option works with your scooter’s CVT system to optimize throttle response, hill climbing, and overall acceleration.

Compatible with a wide range of models and configurations, this kit is ideal for riders who want reliable upgrade parts that stay in your performance window without sacrificing reliability. It’s 100% new and built to handle daily riding as well as weekend rides on longer commutes. Typical applications include popular scooter brands that use the 139QMB engine family, providing an upgrade path for both casual riders and enthusiasts seeking more control over their take-off and acceleration curve.

How it works — The torque spring and clutch springs alter the way the variator engages with the drum. Higher-engagement springs offer quicker clutch grab, while softer springs yield smoother engagement. By choosing the right kit configuration, you can tailor your scooter’s performance to your riding goals, from everyday commuting to more spirited weekend rides.

The kit includes:

• One blue torque spring
• Three clutch springs (1K, 1.5K, 2K equivalents) for RPM and grip tuning
• Clear installation notes and compatibility guidance

Care & usage — After installation, optimize your CVT setup by testing throttle response on flat ground, then gradually increase incline testing to gauge engagement and hill-climb performance. Regular maintenance of your variator and clutch area helps ensure consistent grip and longer life for your springs. Always verify compatibility with your specific model and engine type (139QMB/139QMA) before installation to achieve the best results.

Why settle for stock performance when you can tailor your scooter’s take-off, climb capability, and top-end feel? This kit gives you the levers to pull so you can ride with confidence, no matter the road ahead.
