2018 Harley-Davidson Street Glide — Should You Buy One?

Typical asking price: $15,000–$24,000. This is one of the more reliable vehicles in its class — here's what to watch for anyway.

Kestrel Take

The best-selling bagger in America, and the Milwaukee-Eight engine that arrived in 2017 fixed most of the heat and vibration complaints of the old Twin Cam. A well-maintained one is a genuinely durable touring bike. Check for heat-related wear and the quality of any modifications.

What we checked

No public record to reconcile against

We don't yet have a public record to check this one against. Federal complaint records thin out badly on older vehicles, so there is little to check against. What follows is our own write-up, and it has not been reconciled against an official record. Treat it as a starting point, not a verdict.

Known Issues for the 2018 Harley-Davidson Street Glide

Ranked by wallet impact. These are documented, recurring problems — not freak accidents.

Rear cylinder heat on the riderMedium

Even the improved Milwaukee-Eight runs hot in traffic; excessive heat can indicate a tune or exhaust issue. Test it in stop-and-go conditions.

Repair cost: Not yet priced

Source: not yet checked against public records.

Cam chain tensioner wear (early hydraulic units)Medium

The hydraulic tensioners are far better than the old spring units but still wear; listen for chain noise.

Repair cost (estimate): $400-$1,200

Source: not yet checked against public records.

Aftermarket tune and exhaust qualityMedium

Most have a Stage 1 tune, exhaust, and intake. A good tune is fine; a bad one causes heat and drivability issues.

Repair cost: Not yet priced

Infotainment (Boom Box) glitchesLow

The touchscreen infotainment can freeze or lose connectivity.

Repair cost (estimate): $200-$800
