Ultimate Guide for Harley-Davidson Engine Guards
What Does an Engine Guard Actually Do?
Engine guards serve three main functions:
- Crash protection – Engine cases, frame, fairings and crankcase
- Highway peg mount – Lets you stretch your legs on long hauls
- Expands Upgrade – Mount auxiliary lights, GoPro cameras, and even small speakers
| Risk Without Guard | Consequence |
|---|---|
| Parking lot tip‑over | Scratched engine covers, bent foot controls, cracked fairing |
| Low‑speed slide (under 30 mph) | Ground‑down crankcase, destroyed exhaust |
| Leg pinned under bike | Broken bones, severe road rash |
| Falling on soft ground | Still enough force to dent an unprotected engine case |
One forum member reported his mustache guard saved the bike without a scratch during a tip‑over on gravel. Another rider who hit a deer at 65 mph said the guard kept the motorcycle from crushing his leg during the slide.
How to Choose an Engine Guard (Mustache, Meathook, Highway Peg, Chopped)
| Engine Guard Style | Main Compatible Models | Material & Build | Installation Difficulty |
|---|---|---|---|
| Mustache |
Softail ( Street Bob, Fat Boy) Dyna ( Street Bob, Super Glide) Touring (Road King, Road Glide, Electra Glide, Street Glide) |
AISI-1090 high carbon steel (Chrome/Black) | Moderate – One‑piece construction requires aligning upper and lower mounts; may need horn relocation or adapter bracket; two people recommended |
| Meathook |
Softail ( Street Bob, Fat Boy) Dyna ( Street Bob, Super Glide) Touring (Road King, Road Glide, Electra Glide, Street Glide) |
AISI-1090 high carbon steel (Chrome/Black) | Moderate – Two‑piece installation with separate left/right brackets; more bolts; must align both sides; sliders require proper tightening |
| Highway Peg | Universal – Fits nearly all Harley models with standard 1.25" round tubing | AISI-1090 high carbon steel (Chrome/Black) | Easy – Bar mounts with U‑bolts; pegs clamp onto the bar with simple brackets; no horn relocation or wiring changes; one person can do it |
| Chopped | Road Glide, Street Glide, Road King (lower fairings or minimal look) | AISI-1090 high carbon steel (Chrome/Black) | Easy – few bolts; installation usually under 30 minutes |

Reddit Riders Also Asked
I dropped my Street Bob in a parking lot. Now the primary cover is scratched to hell. Would a crash bar have saved it?
Yes. Even a cheap bar takes the hit. Now you’re looking at a $400 cover replacement plus paint.
---
My buddy says meathook guards are just for looks. True?
False. Meathooks with replaceable sliders work great. I lowsided at 25 mph—slider got chewed, bar bent slightly, engine zero damage.
---
Can I install an engine guard myself or pay the dealer?
Do it yourself. It’s six bolts. Just buy a torque wrench and watch a YouTube video.
---
Will a mustache guard fit my 2022 Low Rider S?
Yes, but NOT if you have Extended Reach Forward Controls. And check that your Heavy Breather air filter doesn’t hit the bar.

FAQ for Harley‑Davidson Riders
Do engine guards really save the engine in a crash?
Yes for tip‑overs and low‑speed slides (under 30 mph). At highway speeds, they help but won’t prevent all damage.
---
Which style offers the best protection?
Traditional full‑wrap guards give the most coverage. Mustache and chopped styles offer slightly less but are much cleaner looking.
---
Can I add highway pegs to any engine guard?
Not all. Mustache guards have built‑in pegs. Traditional guards need bolt‑on peg mounts. Check the product description.
---
How long does installation take?
45–90 minutes for a first‑timer. 30 minutes if you’ve done it before.
---
Will a guard affect my cornering clearance?
Rarely. Most are designed to stay above the lean angle limits of a Harley. But very wide meathook bars on a lowered bike might drag first—ask other riders with your exact setup.
