This new product bolts right onto the throttle housing on electric start CRFs, KTMs and Husqvarna 4-strokes. By mounting the button onto the stock throttle housing, it's close enough to be reached with the same hand that rotates the throttle open. The main benefits of Ride Engineering kill and start switches is to make more room on the handlebars for handguards, lap counters, stop watches or to position your levers in the optimal location. A side benefit is making handlebar replacement faster and easier because there are less parts strapped to the bars that need to be removed (without the tiny Phillips screws). Installation is simple by splicing in two wires. 100% mechanical, so it's very simple to repair if it stops working, just unscrew the main ring to get at the internals. Note: If you damage the switch in a crash, it's possible to lose the internals, and Ride Engineering has a rebuild kit available.
