Factory-preassembled 123cc fuel tank set features a pressure cap with a 1-piece profiled seal for perfect fitment and sealing. The fuel tank includes tank inserts (1 & 2cc) to fine-tune fuel capacity as well as an integrated stone filter. The integrated splashguard protects the brakes from fuel. New fuel tube holders are attached to the tank by screws. These holders prevent the fuel tubes from moving around during racing and help prevent the fuel tube from contacting the flywheel.
