JAVIK handlebar switch assembly replaces OEM 5LP-83973-01-00 to restore engine start/stop, headlight hi/lo/off and choke control on compatible Yamaha ATVs.

If your Yamaha ATV's left control cluster is worn, damaged, or intermittently working, this direct-fit JAVIK replacement offers the same harness connector and plug‑and‑play installation as the original. It’s designed to match OEM function and layout so you can swap it into models like Big Bear, Bruin, Grizzly, Kodiak, Raptor and Wolverine within the specified year ranges. The part replaces OEM number 5LP-83973-01-00 (also compatible with 5LP-83973-00-00 replacements) and ships as a single complete handlebar switch assembly.
