+2mm larger throttlebody for the MY12-16 Honda CRF250L. The addition of this bolt on allows up to +12% more airflow to your engine! This part is OE on the MY17-20 CRF250L, CBR250/300, and MY21+ CRF300L models. This throttlebody is a key component to how the original CBR250R and the MY17+ CRF250L creates more brake horsepower than the original MY12-16 CRF250L. To install, simply swap the sensor pack and idle air control valve from the your OEM throttlebody and install onto this new core. The rest is plug and play.
Note:
This bolt on requires new engine mapping to run properly, please check out the tuning section for the MY12-16 CRF250L for supporting tunes.
