Top cases are the most practical luggage upgrade you can bolt to a motorcycle. SHAD and Oxford cover every capacity from compact commuter boxes through large-capacity touring lids, with fitments spanning hundreds of bike models. A 29L daily lock-box or a 47L cargo-rated case both install in around 10 minutes with the correct SHAD mounting plate.
Choosing the right top case
Capacity determines the purchase. A 29L case suits solo commuters carrying documents and wet weather gear; 34L clears a full-face helmet in most configurations; 39L to 40L handles two-up day touring; 47L is the ceiling of the SHAD SH-series and suits long-haul touring where both riders share a single case. Oversized cases shift centre of gravity rearward, so match volume to actual use rather than buying the biggest available.
SHAD vs Oxford: what each brand does
SHAD builds the hard cases. The SH-series uses polycarbonate shells with integrated locking, carbon-look panels on the SH34 and SH39, an external cargo rack on the SH40, and a red rear reflector on the SH47. Every SH case mounts via a SHAD-specific plate matched to your exact bike model and year, covering over 200 platforms including Yamaha, Honda, Kawasaki and Suzuki. Oxford supplies the Aquatex over-cover, a waterproof textile wrap that adds an outer weather barrier over any hard case during wet touring stages.

Mounting: the step most riders skip
Every SHAD case requires a bike-specific mounting plate, not a generic adapter. The SHAD mount for the Yamaha DELIGHT 125 (2017 to 2026) is one example of a catalogue spanning over 200 models. Confirm the plate reference before ordering the case. Plate installation takes around 10 minutes with standard hand tools. Never use an unmatched adapter as load shift at speed can compromise the locking mechanism.
Frequently asked questions
What capacity top case fits a full-face helmet?
A 34L top case comfortably fits most full-face helmets. A 29L case may fit a compact open-face helmet but is tight for full-face. For two-up storage, step up to 40L or 47L.
Do SHAD top cases need a specific mounting plate for my bike?
Yes. Every SHAD SH-series case requires a SHAD-specific mounting plate matched to your exact bike model and year. Shark Leathers stocks plates for a wide range of Yamaha, Honda, Kawasaki, Suzuki and other platforms. Check the mount compatibility listing before ordering the case.
What does the Oxford Aquatex top box cover protect against?
The Oxford Aquatex cover is a waterproof textile sleeve that fits over any hard top case. It adds weather protection during sustained rain, keeping water out of lid seams and preventing pooling on the case surface during touring. It is a companion product, not a replacement for a quality hard case.
