A brand new camshaft purpose built for the KLX140! The KLX140 is the ultimate trail bike. It just needs a little more power.

Note: The BBR KLX140 Performance Camshaft installs the same as the OEM camshaft (valve clearance IN: .002"-.003" / EX: .004"-.006"). We recommend you purchase an OEM Kawasaki KLX140 Service Manual to assist you when installing this camshaft.

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. 

• Raises rev-limiter 1200 rpm over the OEM ignition
• Hotter advance curve for better performance
• Direct replacement for the OEM CDI ignition box
