SIDI · Boot Parts
The SIDI Strap for ST/MX Buckle Long is a replacement strap made to bring back a secure, dependable closure on SIDI boots that use the ST/MX buckle system. It’s designed as a direct-maintenance part for riders who want to replace a worn or damaged strap and keep their existing buckle setup working as intended.
This long strap is offered in multiple colors to help match the look of the boot, and it’s listed as fitting a wide range of compatible SIDI models. It’s sold individually for straightforward boot upkeep when only a strap needs replacement.
Built to work with SIDI ST/MX buckle systems, this long replacement strap is intended to restore the buckle’s ability to hold the boot closed securely. It’s a practical choice when the original strap is worn out and the rest of the buckle hardware is still in serviceable condition.
The strap is available in Army, Black, Grey, Red, and White. These options make it easier to keep a consistent look when replacing a single worn strap, or to match the strap color to the rest of the boot’s existing buckle components.
This replacement part is listed to fit a broad range of SIDI boots, including Adventure 2 Gore, Crossfire 3 SRS, Crossfire 3 TA, ST, ST Air, Mag-1, Rex, Rex Air, Vertigo 2, X-3, X-3 Enduro, and more models as shown in the fitment list on the page.
