NEW BBR BBR KLX/DRZ110 143cc Big Bore Kit
NEW BBR BBR KLX/DRZ110 143cc Big Bore Kit. This is the largest bore kit available that does not require boring your engine cases for additional cylinder sleeve clearance. New aluminum cylinder with plated aluminum liner, high performance BBR MX camshaft with lightweight piston and gaskets are included in this complete and ready to go kit. Please note application information below. There are a few engine changes for the 2010 and newer models that effect the fitment of this item.
411-KLX-1402 does not include the BBR camshaft and can be used on 2003-Present year models. We have found that a very small number of KLX110's (about 1 out of 100) have cases that run a little tight and do not allow the oversize sleeved cylinder to be installed. This is a very rare case scenario and BBR has a cure for this. Aluminum cylinder with plated aluminum sleeve.
Gasket kit including cylinder head, cylinder base and LH ignition cover gaskets. 411-KLX-1402 does not include the BBR camshaft and can be uséd on 2003-Present year models.
