Billet Proof Designs' chrome 3-position ignition switch is a direct-fit replacement that provides Off, Ignition, and Ignition-with-Lights positions and ships with two tamper-resistant round keys. This compact, chrome-plated switch is built to replace HD# 71705-97 and works on many Harley models and custom builds. It arrives with pre-installed 14" lead wires terminated with eyelet connectors and a key-position sticker for simple installation. The switch body measures 1 3/4" long with a 1 3/8" outer diameter and fits a standard 3/4" mounting hole, making it straightforward to swap into compatible bikes.

Will this ignition switch fit my Harley Sportster or Dyna?

Yes — this Billet Proof component is made to match the fitment of the original HD# 71705-97 and fits a broad range of Harley motorcycles. Confirm your model year against the fit list to ensure compatibility.

  • Fits 1979–2003 Harley Sportster (XL) models.
  • Compatible with 1991–2005 Dyna (FXD) models, except FXDWG Wide Glide.
  • Suitable for many custom motorcycle applications using a 3/4" dash hole.

How difficult is installation and what wiring is included?

Installation is typically quick for anyone comfortable with basic motorcycle wiring and dash removal. The switch comes with 14" of pre-attached lead wire and eyelet terminals so you can bolt and connect without extra crimping or soldering in most cases.

  • Three-wire design: Off, Ignition, Ignition-with-Lights positions.
  • 14" leads with eyelet terminals already installed for easy hookup.
  • Fits a 3/4" hole and inserts into a 1 3/4" long switch body for secure mounting.

What are the build and security features of this switch?

The switch is chrome plated for a classic appearance and corrosion resistance while the supplied keys are tamper-resistant round types to reduce the chance of unauthorized access. A key-position sticker helps indicate each setting at a glance.

  • Durable chrome plating for a showroom finish and weather longevity.
  • Two tamper-resistant round keys included for better security and spares.
  • Key-position sticker included for quick reference during installation.

Can this switch be used on custom motorcycle projects?

Absolutely — the switch's common dimensions and wiring make it a popular choice for custom builders. Its clean chrome look and standard mounting size let it integrate into custom dash designs without major modification.

  • Standard 3/4" mounting hole fits many aftermarket and custom dashes.
  • Chrome finish complements classic and modern bike aesthetics.
  • Works as a direct replacement for HD# 71705-97 in many conversions.
