About the Lexmoto Viper 125

Get ready for the Lexmoto Viper. With updated technology, aggressive attitude and torquey power plant, the Viper lets everyone know its arrived. The updated fuel injection system gives exhilarating performance at a price that makes sense. With the USD forks and combined braking you can be sure to have the handling you need, exactly when you need it. The throaty motor is not the only sound you will hear from the Viper, as this bike is fitted with a sound system using USB, Bluetooth and FM connectivity, which allows you to listen while you ride, or share out loud when you have parked up.
