Harley-Davidson Street Bob Parts & Accessories

Street Bob parts: two bikes with one name

About 2,300 Street Bobs are taxed in the UK and another 1,300 are on SORN. Two of them can share a name and almost no parts: the Dyna Street Bob ran to 2017, and the Softail Street Bob replaced it for 2018 on a different frame.

The catalogue files every 2021 to 2024 Street Bob under the 114, so this page skips from 2020 to 2025. A 2006 Dyna has its own code, FXDBI; 506 of its 513 parts are on the 2007 list.

What crosses 2018, and what doesn’t

Across the 2006–2017 Dyna and the 2018-on Softail we list 915 live genuine parts, and 341 fit both. Year to year the Dyna list carried 98 to 100 per cent; across 2018, 336 of the 541 on the 2017 list made it. Not one hand grip, handlebar, lever kit, seat, sissy bar, rack or saddlebag crosses. All 26 shifter pegs do, as do riser kit 56931-10 and the front tyre, the 100/90B19 Michelin Scorcher 43258-07B. The rear changed with the frame: 160/70-17 (43250-07B) on the Dyna, 150/80B16 (40878-11) on the Softail. Screens go the other way: every genuine windscreen listed for a 2006–17 Dyna also fits the 2018-on bike, the Quick-Release Compact 58346-06 and 58348-06.

A sissy bar is a four-part order

A 2018-on Street Bob takes the HoldFast upright 52300442 (chrome), 52300446 (gloss black) or 52300448 (short) on docking kit 52300645 or 52300646. It is not the Fat Boy and Breakout upright, 52300437 and 52300439: neither set fits the other bike. The upright’s listing asks for three more parts, two of which have no page here: the docking kit, then the Street Bob pillion 52400128 or a two-up seat such as the Badlander 52000300, then footpeg support kit 50500769 or 50500771 with footpegs. Choose the sissy bar first; the Sport luggage rack 50300124B or 50300125B hangs on that upright and nothing else.

Bars, controls and the 2025 list

Genuine handlebars for a 2018–24 Street Bob are the Moto Bar 55800856, Fused 55801016 and Reach 55800715; the 2025 list drops all three for the Hollywood bar 55801579. That is the second break in this parts book: 103 parts on the 2024 Street Bob 114 list are missing from the 2025 list, all 45 hand grips among them. The 2025 bike lists two, the Kahuna 56100705 and 56100706, and lever kit 36700301 in place of 36700209 to 36700211. That is Harley’s list, not proof an older grip won’t go on. The genuine forward control kit for a 2018-on Street Bob is 50700060 in black or 50700061 in chrome, shared only with the Softail Standard and the Low Riders.

Close relatives

The 2020-on Softail Standard is the Street Bob in the parts book: in 2020 only five of the 634 live parts on the 2020 Street Bob list did not also fit it. The HoldFast upright, rack and Badlander are shared with the Heritage Classic, Deluxe and Slim, not with the Fat Boy. The Breakout lacks 72 of the 668 parts we list for the Street Bob across 2018 to 2020 and 2025 on, the Fat Boy 78 and the Fat Bob 114 111.
