Fitment Notes & Exceptions
  • Professional installation and carburetor rejetting recommended
  • Fits 2003-2009 models ONLY
  • BBR has found that a very small number of KLX110's have cases that run a little tight and do not allow the oversize sleeved cylinder to be installed. This is a very rare scenario and BBR has a cure for this if you contact them directly.
