KITACO, a manufacturer which develops and produces motorcycle parts has newly released the “NEO Big Bore Kit of 164cc Displacement”, “NEO Big Bore Kit of 181cc Displacement” and the “Big Throttle Kit” for MSX125 (GROM).

The design concept of the two types of the “NEO Big Bore Kit incorporate more advanced performance and durability. The attached cylinder head, which has an ideal combustion chamber shape, adopts a highly efficient port form and a big valve.

Aside from that, it also comes with an exclusive high profile camshaft and an optimum high compression piston, which give the rider the sensation of the powerful torque and the smooth engine blow-up.

The “Big Throttle Kit” has a large throttle body with a larger bore compared to the original size. It contributes to its power increase by raising the intake amount to a large extent.

You can install an oil cooler to the shroud bracket after you remove the air cleaner box.
