1. Product Overview
This JXMOTONG Electric Motorcycle Throttle Turn Grip Handlebar is designed for precise speed control on electric motorcycles. It features a durable plastic construction and is compatible with Sur-Ron Light Bee S, Sur-Ron Light Bee X, X160, and X260 models.
The throttle handle incorporates a rolling bearing for smoother operation and more responsive acceleration. The design ensures stable and ingenious speed control.
2. Installation
2.1. Pre-Installation Preparation
- Power OFF the vehicle first! Always turn off the main power and disconnect the battery pack before starting installation. This prevents accidental throttle engagement, which can cause the bike to lurch forward unexpectedly.
- Inspect all components: Verify the throttle body, mounting clamps, screws, and wiring harness are free of damage. Pay extra attention to the connector pins and wires to avoid poor electrical contact later.
2.2. Installation Steps & Critical Notes
- Alignment & Positioning: Slide the throttle body and mounting clamps onto the handlebar before securing the bar to the bike. This prevents wiring harness strain or damage from misalignment.
- Adjust the throttle angle so the flat side faces forward. This ensures smooth rotation without interfering with brake levers, switches, or controls.
- Leave a ~2mm gap between the throttle and the end of the handlebar. This prevents binding and ensures the throttle can fully return to the closed position.
- Securing the Mounting Screws: Use a 4mm hex key to tighten the two clamp screws in a crisscross pattern, in two stages (partially tighten first, then fully tighten). Overtightening can crack the plastic housing. The correct tension is when the throttle stays fixed but still rotates and returns smoothly. Over-tightening will cause the throttle to stick or bind.
- Wiring & Waterproofing: Align the connector's keyway and push firmly until you hear a click to ensure a secure connection. Loose connections cause intermittent power issues. Apply a small amount of silicone sealant to the connector to reduce the risk of water damage and short circuits in wet conditions. Route the wires along the frame and secure them with zip ties. Avoid routing them near brake lines or sharp edges, where they can be pinched, stretched, or worn through during use.
3. Operating Instructions
3.1. Post-Installation Testing
- Return-to-Idle Test: Twist the throttle fully, then release it. It must snap back to the closed position quickly and smoothly, with no sticking or delay. If it does not return freely, check for over-tightened screws or interference with other components.
- Functional Test with Power On: Reconnect the battery and turn on the power. Slowly twist the throttle and confirm the motor accelerates smoothly. Release the throttle and confirm the motor stops immediately.
- Full Travel Range Test: Twist the throttle from 0 to full open. The action must be smooth throughout the entire range, with no binding or surging.
4. Maintenance
Regular inspection of the throttle grip and cable is recommended to ensure optimal performance and safety. Check for any signs of wear, damage, or loose connections.
4.1. Cleaning
Wipe the throttle grip and housing with a damp cloth. Avoid using harsh chemicals or abrasive cleaners.
4.2. Lubrication
Do NOT spray oil, WD-40, or lubricants into the throttle mechanism, as these will damage the internal Hall effect sensor.
5. Troubleshooting
5.1. Common Mistakes to Avoid
- Do not use a heat gun on the plastic throttle housing, as this will cause it to warp or crack.
- Do not spray oil, WD-40, or lubricants into the throttle mechanism, as these will damage the internal Hall effect sensor.
- If this is an aftermarket throttle, confirm the connector is compatible with your Light Bee model (S vs. X versions have different pinouts) to avoid compatibility issues.
- Never force the mounting screws. The plastic housing is easily stripped, which will cause the throttle to move unexpectedly while riding.
