Stock CRF110F - 50.0mm bore, 55.6mm stroke
Note: This bore kit is designed for the 2013-2018 CRF110F. While the newer motors are functionally almost identical, the newer models require a port for the engine temperature sensor. We're working on a new casting - but these take time. Once available, we'll note it here.
