The Namura NA-10012K Top End Kit is a complete standard-bore replacement solution for select Honda 700 engines. Designed for dependable service and consistent performance, this kit includes the piston, piston rings, wrist pin, wrist-pin clips, top-end bearing, and gasket kit required for a thorough top-end rebuild. The 11:1 compression ratio supports efficient combustion and reliable engine operation when matched to the applicable factory specifications.
Built using Namura manufacturing processes, the piston features MOS2, or Teflon/molybdenum, coated skirts. The rolled-on coating process creates a strong bond while helping reduce friction, improve heat transfer, and minimize the risk of cold seizures. Machined smooth heads help reflect combustion heat and reduce carbon buildup, while anodized domes increase heat resistance and durability. The hypereutectic casting process adds silicon for controlled expansion, improved wear resistance, and enhanced performance in higher cylinder temperatures.
This Namura top-end kit fits select 2006-2008 Honda TRX680FA Rincon IRS models, 2010-2013 Honda MUV700 Big Red models, and 2014-2016 Honda SXS700M2 Pioneer 700 models. Verify the vehicle year, model, engine configuration, and standard-bore application before installation.
