Let your KLX110 (2010 and newer) or your KLX140/L/G perform it's best! This box moves up the rev limiter allowing higher revs. It also has a hotter advance curve from the OEM box. This allows for a bit crisper throttle response and easier starting. This is a "must have" for modified KLX110's and KLX140's. Raises rev-limiter 1200 rpm over the OEM ignition Hotter advance curve for better performance Direct replacement for the OEM CDI ignition box
