WEIYINGSI Thumb Throttle with Dual Brake Lever for 50cc–250cc ATVs (7/8" Handlebars)

WEIYINGSI Thumb Throttle with Dual Brake Lever Assembly

Designed for a wide range of ATVs, this compact throttle and dual brake lever kit from WEIYINGSI fits most 7/8" handlebars on 50cc, 90cc, 150cc, and 250cc machines — including Roketa, Taotao, Sunl, and Kazuma models. The setup invites a confident riding feel, whether you’re carving through trails, cruising backroads, or tending a yard. The tactile thumb control and paired brake levers are engineered to respond smoothly to quick inputs, helping you stay in sync with the ride.

One standout feature is the built-in speed limiter. You can set and maintain a chosen top speed, which allows you to tailor the ride to conditions or personal preference. The included parking brake function locks the hand lever in the activated position, providing a controlled hold during stops and a more predictable return when you resume riding. This combination of speed management and hold capability adds a practical layer of control for everyday use.

Durable, ride-ready construction

• Aluminum construction combines strength with light weight for rugged outings.
• The brake cable switch tolerates long-term use, rated for up to 50,000 activations, supporting reliable performance over time.
• Note: this 22mm thumb throttle is designed for front wheel drum brake setups and is not compatible with front disc brakes.

Real-world use cases

Imagine a crisp morning ride where the throttle responds with a precise, repeatable feel as you set a comfortable top speed. In a workshop or farm setting, the parking brake function can help you pause confidently without losing control. The kit is well-suited for owners of Roketa, Taotao, Sunl, Kazuma and similar brands, offering a clean, integrated control solution on ATVs with 7/8" handlebars.

Residents and enthusiasts alike may appreciate how the aluminum body and durable cable system stand up to daily use and varied weather. While results depend on each ATV’s overall setup, the throttle can contribute to smoother acceleration, steadier speed management, and more predictable handling on diverse terrains.

Installation and care tips

• Avoid over-tightening the locking screw to minimize damage if the vehicle tips or falls.
• Apply grease to the throttle cable ends and the cable keeper to promote smoother acceleration and longer life.

Overall, WEIYINGSI offers a robust throttle assembly that emphasizes responsive control, practical speed management, and dependable operation under real-world riding conditions. Use this as a possible upgrade to refine your ATV’s feel and consistency without promising guaranteed results.
