  • The SP-1 is compatible with a wide range of motorcycles, provided there is a rear fender surface and a passenger seat to secure the bag. Ensure adequate clearance from exhausts, blinkers, and suspension.

    Harley-Davidson

    • Softail & Dyna Street Bob
      Fits with stock or center-mounted aftermarket taillights.

    • Softail Fat Bob
      Compatible, but the OEM upswept exhaust can sit close to the bag. A non-upswept exhaust is recommended for proper clearance.

    • Sportster (and Yamaha Bolt)
      Fits, but bikes with side-mounted rear blinkers require a narrower option. (For SP-1 users, this may require relocating blinkers depending on setup.)

    • Softail Low Rider S / ST
      Works with stock taillight or center-mounted aftermarket taillight.

    • All Dyna Models
      Generally compatible. Contact us if you need fitment confirmation for a specific setup.

    Yamaha

    • Bolt
      Same considerations as Sportster fitment—side-mounted blinkers may require repositioning or a narrower setup.

    Honda

    • Rebel / Shadow
      Compatible with standard passenger-seat setups.

    Indian

    • Chief
      Works when equipped with a passenger seat or step-up seat.

    • Scout / Scout Bobber
      Fits when using a step-up seat or passenger seat for securing the bag.

    Other Motorcycles

    Fits most bikes with:

    • A rear fender surface for the bag to rest on

    • A passenger seat that locks down over the bag

    • Adequate space between blinkers and shocks to accommodate the bag length

    General Installation Note

    For optimal security, install the SP-1 only on motorcycles with a passenger or step-up seat that can lock the bag in place. The bag is designed to sit directly under the passenger seat.
