416 big bore kit

+2mm (87mm) big bore kit, includes JE Pistons complete piston kit and a Cometic top-end gasket kit. This kit is a nice ‘wake-up’ call for your 400EX, 400X or XR400, and still gives you another bore in the stock cylinder later. Available in 2 different compression ratios.

This kit requires your stock cylinder to be bored and honed – if you’d like us to do that work, just contact us.

Fits:

Honda TRX400EX 1999-2008

Honda TRX400X  2009-2014

Honda XR400 1996-2007
