SHAD — a global leader in motorcycle luggage and pioneers of expandable case technology — introduces the SH38X expandable side cases, an innovative set of expandable side cases designed for today’s premium motorcycles. With award-winning engineering and exceptional versatility, these cases are perfect for commuters and touring riders alike.

Why Riders Choose the SH38X

Expandable, Secure, and Built for Real Riding

Designed around SHAD’s patented 3P or 4P mounting system*, the SH38X integrates seamlessly with the motorcycle.  A premium Double Locking System secures the case to the bike while locking the lid — both controlled with a single key.
