A matching derby cover can carry a collection’s appearance onto the primary case. Compare the actual finish and precise product application; the films do not establish an engine-performance gain from a decorative cover.
These complete collection films include controls and other trim, but the links and matching results here contain only the reviewed derby covers. Grippy foot supports, heated grips and other collection functions are not features of these decorative covers.
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.
Your bike and other filters apply to the matching results.
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.
Your bike and other filters apply to the matching results.
Redline uses curved machined spokes around a central Bar & Shield design and offers the listed black, red and blue derby-cover references. Black Switchback follows the black anodised collection. The precise part number still matters within a colour: matching finishes do not make two cover applications interchangeable.
The collection films show several cover types together. The reviewed product links on this page are derby covers; a timer cover shown in the film is another item, and neither automatically supplies a complete primary cover assembly. Start from the actual part you are replacing, then check the product’s model and year application.
Both reviewed black Switchback derby covers include mounting hardware. The exact applications differ: 25701519 covers the listed Touring/Trike setups, including specified narrow-profile primary-cover combinations; 25701521 covers the listed Softails and their required primary-cover configurations. Check the complete model/year list, existing primary cover and sealing requirements. A shared black finish does not establish that either reference fits the other application.
