The MSD Enhancer Ignition for Honda® CR125/250 sets new standards for performance engines. An adjustable timing curve allows the tuner to draw more horsepower out of the engine. The stock ignition produces a mere 20 millijoules of spark energy at 10,000 rpm. This is not sufficient to ignite the air/fuel mixture completely in the cylinder, which translates to: misfiring and lost performance. The MSD Enhancer ignition system produces a whopping 100 millijoules of spark energy through the entire rpm range!
