GSI – RocketTeer Sidecar Kit
Best for classic builds that seek a complete, look-consistent sidecar setup. The RocketTeer kit is designed to fit all models, making it a go-to for riders who want a traditional, retro aesthetic with straightforward mounting workflow. Use this when you’re seeking a ready-to-install solution with a vintage vibe and broad compatibility.
Best for: riders pursuing a traditional, old-school appearance with a plug‑and‑play mindset. Limitation: installation may rely on matching to a wide range of bikes, requiring careful alignment for each model.
U-clamp frame mounts are ideal for Harley‑style frames where a sturdy, rigid connection to the bike frame is essential. This option emphasizes durability for long-distance touring and heavy loads. It’s best for riders who want a dependable clamp system that minimizes flex during highway speeds.
Best for: riders with Harley-based frames needing a robust clamp experience. Limitation: may require precise frame compatibility checks before purchase.
1 Pair 22mm Retrofit Handguard Bracket
Best for retrofits where you want a flexible mounting point near the handlebars. These 22mm brackets fit most motorcycles with 22/28mm handlebar cores and are made from aluminum alloy to reduce weight while preserving strength. Use this when space near the handlebar is a constraint but a secure sidecar mount is still needed.
Caution: verify handlebar diameter and clearance with your sidecar’s docking hardware before ordering.
2pcs Mirror/Fog Light Bracket Relocation
Best for riders needing durable brackets to relocate lights or mirrors as part of a sidecar setup. The stainless steel construction resists rust, making it suitable for outdoor use and varied weather. Universal compatibility with standard 10mm turn-signal holes means flexible mounting options.
Limitation: installation may require additional hardware or adapters for non-standard setups.
Detachable 4-Point Docking Hardware Kits
Best for riders who want a detachable docking system that can support quick changes or multiple sidecars. The four-point design offers distributed load and strong anchor points to reduce sidecar wobble. Choose this if you value modularity and ease of swapping sidecars without reworking the entire setup.
Limitation: some Harley models may require adapter hardware for perfect fitment.
Buying Guide
What to consider when selecting motorcycle sidecar mounting hardware:
