KOSO 28mm Throttle Body (DY640000) for the 2021 and newer Honda GROM & Honda Monkey.

As the throttle body and intake manifold are used to control the amount of air flowing to the engine's combustion chamber, they are important elements of the intake system. Using Koso's 28mm Throttle Body in conjunction with this 23-29mm Intake Manifold (DP640000) will give a better air/fuel mixture for a quicker throttle response.
