Billet Proof Designs Black ISO Front Motor Mount — Direct-Fit Rubber for Harley (Replaces 16207-79B)

Billet Proof Designs Black ISO front motor mount is a direct-fit rubber replacement for Harley part 16207-79B, built to restore proper driveline alignment and reduce engine vibration for compatible Touring and FXR models.

If your Harley has a rubber front motor mount that’s become oil-soaked, cracked, or collapsed, this ISO-style mount from Billet Proof Designs offers the same dimensions and function as the OEM 16207-79B so you can return the bike to factory alignment and ride comfort. Made as a rubber isolator rather than a stiff polyurethane unit, this mount is tuned to absorb vibration while matching the original fitment for 1980–2008 Touring (FLH | FLT) and 1982–2000 Super Glide (FXR) models equipped with rubber-mounted engines.

Which Harley models and part number does this replace?

This mount is manufactured to replace OEM part number 16207-79B and fits specific Harley models with rubber engine mounts. It covers 1980–2008 Touring models (FLH and FLT) and 1982–2000 Super Glide FXR models that use a rubber front motor mount.

• Direct replacement for HD# 16207-79B
• Fits 1980–2008 FLH and FLT Touring models with rubber mounts
• Compatible with 1982–2000 FXR Super Glide rubber-mounted engines

Why replace the front motor mount and what happens if I don’t?

The front motor mount sits where oil commonly drips during routine service, and prolonged exposure to oil degrades rubber. As the mount deteriorates, driveline alignment shifts, worsening driveline geometry and potentially stressing adjacent components such as exhaust header pipes.

• Oil exposure causes rubber breakdown over time
• Worn mounts lead to misaligned driveline geometry
• Severe wear can cause exhaust or driveline damage

Rubber or polyurethane — which mount should I choose?

Rubber and polyurethane serve different ride characteristics. This Billet Proof Designs rubber ISO mount prioritizes vibration isolation and a smoother, less harsh ride, while polyurethane mounts transfer more vibration and feel firmer. Choose rubber if you prefer reduced vibration and closer OEM-like comfort.

• Rubber offers more vibration damping for rider comfort
• Polyurethane increases stiffness and transmits more vibration
• This product mirrors the OEM rubber feel and compliance

How difficult is installation and what tools are needed?

Installation is straightforward for anyone with basic mechanical skills and common hand tools, typically taking about 30 minutes. The tapered portion of the rubber mount must point upward toward the engine; if the old mount is badly collapsed, a floor jack can help lift the motor for easier alignment and insertion.

• Standard hand tools required; about 30 minutes labor
• Tapered rubber portion faces up toward the engine
• Optional floor jack recommended if mount or mounts are severely worn

Who is this for? This Billet Proof Designs front motor mount is aimed at Harley owners and mechanics who need an accurate OEM-style rubber replacement for part 16207-79B on compatible Touring and FXR bikes. It’s ideal for riders who want to restore factory driveline alignment and reduce vibration without switching to a stiffer polyurethane setup. If you perform your own maintenance or want a direct-fit replacement that keeps the bike’s original ride characteristics, this mount is a practical and easy-to-install solution.
