The SH51 is a top case designed for adventure riding and touring. High-resistance materials and an aerodynamic shape keep it safe and stable on the road. It takes two flip-up helmets, has an internal mesh to organise small items and carries up to 10 kg. Paired with SH38X Expandable side cases it makes a complete touring set, and it is just as suited to the daily commute as to gravel roads.

• Capacity: 2 flip-up helmets, size M (ECE 22.06)
• Construction: high-quality reinforced polypropylene for maximum strength with minimal weight
• Top cover: anodised aluminium
• Double Locking System: integrated lock and handle, so the case opens, closes, comes off and carries in seconds, one-handed
• Water resistant: durable rubber seal around the lid
• One-key system: top case and side case lock cylinders can be swapped to run on a single key
• In the box: SHAD mounting plate with screws and rack clips. Most bikes also need the SHAD Top Master fitting kit for that model
