Thunder Tiger RL-53H engine features XC2 extreme composite coating with nano-technology from Japan for longer engine life, a special criss-cross pattern etched on the sleeve wall for much lower friction and an oversized heat sink head. These exclusive RL-53H's features deliver much more reliable power and higher torque through the full range of RPM.
The brand-new carb design is mounted on the crankcase with a very effective heat insulator to keep the carb working at stable temperature under all conditions.
