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.
Custom developed by BBR Motorsports for the ultimate upgrade for mini four-strokes. Sized perfectly for fast/aggressive adult mini riders. This is the most important upgrade you can make for an adult sized rider. The stock suspension is too soft for most adults.
