Koso Grom Throttle Body 34mm Throttle 2014-2020

Big bore engines for the Honda Grom 125 will require a larger throttle body so that your engine can perform and run optimally. Koso 34mm Throttle Body will do just that! Perfect for the displacement of 180cc and higher! Throttle body does not come with any sensors, so swapping over the sensors from the stock throttle body is required. Koso Large Intake Manifold is required, the 34mm throttle body will not work with OEM manifold.
All parts listed above are highly recommended when using the Koso big bore and camshaft kits.

NOTE: All of the above parts are not legal for use in California on pollution controlled vehicles. (Road going vehicles) However a race waiver is available.
