TGB Blade 400 Service Repair Workshop Manual PDF VEHICLE/EQUIPMENT INTRODUCTION: The TGB Blade 400 was a larger-displacement variant in the TGB Blade scooter range, offering 400cc of liquid-cooled four-stroke power for riders who needed more speed and torque than the smaller models could deliver. Positioned as a maxi-scooter, the Blade 400 combined the convenience of fully automatic CVT operation with genuine touring capability. Its larger engine provided relaxed cruising at higher road speeds, making it a viable highway commuter and an excellent cross-town transport solution. The 400cc liquid-cooled single-cylinder engine was paired with a robust CVT drive system featuring a reinforced front variator and a larger rear clutch assembly to handle the increased power output. The chassis was uprated with larger diameter brakes, stiffer suspension damping and reinforced bodywork. Despite its larger size, the Blade 400 retained the easy-to-ride character and low operating costs that made the Blade range popular.
