Accessories

Redline brings together precision-machined, forged aluminium pieces in red, blue and black anodised finishes. Those colours describe the collection; each linked product has its own finish and fitment. The rider, passenger and highway pegs and rider footboards have open shapes, raised edges and cleats that H-D describes as gripping boot soles. Optional black rubber Comfort Inserts change their look and feel: 50503139 fits Redline rider footboards, while 50503140 fits Redline rider, passenger or highway pegs. Both insert sets are separate purchases, supplied as pairs, with retaining tabs rather than fitting tools or fasteners.

The hand grips use an anodised aluminium body with rubber contact surfaces. Their glueless design allows removal for servicing without damage, according to the exact listing; that feature belongs to the grips rather than the decorative covers. The brake-pedal pads come in small and large versions with a forged aluminium body and black rubber centre. The matching shifter peg adds tapered ends and a machined bevel, so the controls carry the same design without being interchangeable parts.

The derby cover, timer cover and fuel cap use curved machined spokes with a central Bar & Shield motif. These are appearance details, not engine-performance upgrades. The film shows the collection together, while the links here identify the actual pieces in this category. Choose the correct part, size and finish for the bike, and check any required mounts or separate inserts; a shared Redline name does not establish common fitment or included accessories.

This film presents the black anodised Switchback Collection. Forged billet aluminium, pronounced knurling and rubber contact surfaces give the controls and foot supports their textured character. H-D describes the pieces as lightweight additions, without quoting a weight saving. The black anodising protects the exposed aluminium, while the knurled and rubber areas are intended to provide a secure-feeling contact surface. Those contact features do not belong to every decorative cover.

The collection includes regular hand grips and a separate heated-grip option, rider and passenger footpegs, footboards, mirrors, brake-pedal pads, shifter pegs, derby covers and timer covers. They share a visual treatment, but not one fitment or function. In particular, regular grips 56100564 and heated grips 56100574 have model restrictions including FXBB and FXBR exclusions; a Switchback film on a Breakout trim category does not override those restrictions.

Check the exact member’s fitting parts as well as its finish. Rider footboards 50502476 reuse the original hardware, which is not supplied with them. Mirrors 56000343 include the left and right mirrors and mounting hardware, but some motorcycles need the specified fairing plugs. The actual products in this category are linked below. The black-collection film does not establish the finish or suitability of clear-anodised or other same-name variants.

These lower fairings add wind and weather protection around the rider’s legs. Harley-Davidson describes development using computer airflow modelling, wind-tunnel work and riding assessments. A lever operates the wind deflectors so the rider can adjust airflow and direct engine heat away in warmer weather. The film shows the adjustment, the shape around the legs and the storage built into each side.

Each storage compartment has a push-button, damped door and space for small items such as keys, gloves or a wallet. A removable panel at the leading edge can accommodate optional LED Fog Lamps 68000453, purchased separately. Kit 57100505 supplies the pair of lower fairings, compartment lids and mounting hardware in a primed finish ready for paint. The film discusses matching factory colours, and the catalogue associates the design with the Street Glide Ultra. This particular product reference is the primed kit.

The lower fairings require the appropriate supporting engine guard. Guard 49000284 is chrome and 49000285 is black. Their shape supports the lowers and allows optional highway pegs; the guard may also help protect the motorcycle’s finish in a low-speed tip-over. It does not establish protection for the rider or passenger in a crash. The guards listed here fit the specified 2023-on CVO FLHXSE/FLTRXSE and 2024-on FLHX/FLTRX applications. Road Glide installations additionally need the appropriate fairing support kit, 47201044 or 47201045, and these guards do not fit with Heavy Breather air cleaners.

The lower-fairing kit has a broader fitment list, including specified 2025-on FLHXU and named 2026-on Street Glide and Trike applications. That does not make the two-wheel engine guards suitable for every Trike: Road Glide 3 requires guard 49000330 and two each of fasteners 2708A, 6116 and 4924. Match the lower fairings, guard and support hardware to the exact model and year. Fog lamps and highway pegs remain separate accessories.

The radiator guard places a bright aluminium mesh in front of the radiator on a centre-cooled Milwaukee-Eight Touring motorcycle. Harley-Davidson describes it as a way to help shield the radiator from road debris while adding a rugged, finished appearance. The film shows the mesh and its position on the motorcycle, and identifies the CVO Road Glide RR as the original application.

Its design follows the factory radiator installation, with strength, straightforward fitting and airflow as the stated priorities. Harley-Davidson says the mesh leaves the intended radiator airflow unobstructed. Those are design claims for the guard; it is not a guarantee against every impact or a claim of increased cooling performance.

Product 57300493 is listed for 2023-on Touring models with centre-cooled Milwaukee-Eight engines. It does not fit with fairing lowers. The current product restriction is broader than the film’s reference to original-equipment lowers, so treat any lower-fairing installation as an exclusion. Check the actual cooling configuration and installed equipment before choosing the guard.
