JAVIK Left Handlebar Control Switch for Honda TRX300 FourTrax (1988–1995) — Start/Stop, Headlight & Choke

JAVIK's left-handlebar control switch replaces the OEM start/stop, kill, headlight and choke controls for Honda TRX300 FourTrax ATVs (1988–1995), restoring full left-side command and factory-style function.

If your Honda FourTrax 300 has a worn, broken or non‑responsive left handlebar control, this JAVIK replacement mirrors the original layout and electrical functions so you can ride with confident control. Engineered to match OEM part numbers 35200-HC4-004, 35200-HC5-000 and 35200-HC5-010, the unit is a direct-fit aftermarket option for most TRX300 2x4 and 4x4 models produced between 1988 and 1995 (not compatible with TRX300EX Sportrax edition). The module includes start and stop/kill switches, a headlight on/off and high/low selector, plus a choke lever — all housed in a compact left-side assembly built for straightforward installation.
