Stock Heads Only
Fits 2002-Current KLX110 & KLX110L Bikes
Easy bolt-on power. 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.
- Aluminum cylinder with plated aluminum sleeve
- BBR high-performance camshaft
- 60mm lightweight aluminum piston
- Gasket kit including cylinder head, cylinder base and LH ignition cover gaskets
411-KLX-1402 does not include the BBR camshaft and can be used on 2002-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. Please call 888-668-6227.
