How to Remove the Speed Limiter on the Liexing 125?
3 Answers
With the ignition switch turned off, rotate the right handlebar grip to the maximum position while holding the brake lever fully. Then, with your left hand, turn on the ignition switch while holding the left brake lever, and release the right handlebar grip and right brake lever with your right hand. After releasing the handlebar grip completely, quickly rotate the right handlebar grip to the maximum position and release it twice in succession. Ensure that the actions of holding the brake lever with your left hand and rotating the handlebar grip with your right hand are completed within 5 seconds.
I've been riding the LIEHANG 125 for a while and think speed limit removal should be approached with caution. The speed limit on the LIEHANG 125 is typically electronically controlled, such as being set in the ECU. Removing it requires professional tools to tune the ECU or replacing the so-called CDI unit to bypass the restriction. There are modification kits available online, and I've tried them myself, but you have to disassemble the dashboard and connect wires—improper operation can damage the circuit board. After success, the speed does increase a bit, but the engine load increases, fuel consumption rises, and braking distance lengthens—especially unstable during sharp turns. I don't recommend riding a speed limit-removed bike daily; it's only suitable for occasional use on closed tracks. Safety first—modifications may void the warranty, and traffic laws in some areas strictly prohibit this practice, with fines if caught. Regularly checking tires and the braking system is more practical than chasing that extra bit of speed.
From a safety perspective, removing the speed limiter on the NX125 poses significant risks. The factory-set speed limit is designed to protect riders by ensuring stability in complex road conditions. Once removed, the bike's handling deteriorates at high speeds, especially on wet roads where it becomes prone to skidding and accidents. I personally experienced delayed response and noticeably longer braking distances after modification—one near-collision scared me badly. The modification process may also damage electronic components or cause overload failures, leading to more maintenance headaches. Don't risk it for temporary thrills; think differently—keeping it stock ensures durability. Focus on regular chain and oil maintenance instead; upgrading riding skills is more worthwhile than hardware modifications. Remember, speeding on public roads isn't just dangerous—it carries severe legal penalties.
