Bought this pipe for a 2012 KLX110L. It's advertised as being made for the bike, but I suspect it's really made for the older model KLX110. It's easy to install and bolts right up, but when you put the plastic back on, you'll find that the pipe pushes up against the plastic side plate at its front edge. When you ride, it melts the plastic there. In addition because the pipe is completely straight as it runs back, your right boot will get melted against the side of the pipe. Don't think you'd want to ride with just sneakers and shorts on! Sounds good, and there's an obvious improvement in throttle response and acceleration.
