FXRS-SP Low Rider Sport

1985 option; separate model 1987 or 1988 to 1993 or 1994

The FXRS with the FXRT's taller suspension and twin front discs, but no fairing. Many riders see it as the best handling FXR.

Overview

Rider says the lowered Low Glide drew poor reviews, so for 1985 Harley offered an FXRS-SP "Optional Performance/Suspension Package" with the FXRT's taller suspension and dual discs (Rider, Sep 2017). The SP option carried on for the 1986 Low Rider (Rider, Sep 2017).

When it became a separate model is unclear: Rider says 1987 and Hot Bike lists 1988 (Rider, Sep 2017; Hot Bike, "Separating the Men From the Boys"). Moto Gallery gives 1986 to 1993 (Moto Gallery FXR overview). Harley's 1987 owner's manual already gives the FXRS Sport Edition its own column in the spec tables (Harley-Davidson 1987 Owner's Manual). Wikipedia says the Low Rider Sport was discontinued in 1994 (Wikipedia, "Harley-Davidson Super Glide").

Cycle World's July 1990 test found about 2 inches more suspension travel than the FXRS and twin front discs, and ran a 13.17 second quarter mile at just over 100 mph (Cycle World, Jul 1990).

Known issues

Rubber mounts and stabilizer links

The whole design depends on three elastomer mounts and two adjustable stabilizer links (Rider, Sep 2017). Buyer's guides suggest checking them on any used FXR (Moto Gallery FXR overview). Typical wear symptoms and replacement intervals unverified.

1992 to 1994: caged cam bearing

Rider notes that 1992 Evos switched to a caged needle bearing for the camshaft and calls a full-complement bearing a required swap when changing cams (Rider, Sep 2017).

About the unverified flag: it marks a detail we have not yet been able to confirm in a published source, such as a factory document, owner's or service manual, or period magazine test. Where a table cell shows only the flag, we have not found a reliable figure. We keep these details visible so they can be checked. If you have a source, please tell us.
