Install & Fitment Details
The SP-1 is designed to be installed under a passenger seat and uses the seat itself to lock the bag securely in place.
A passenger seat is highly recommended for proper fitment and stability. Without one, the bag will not mount as intended.

• Softail Fat Bob – Fits, but stock upswept exhaust may cause clearance issues. Aftermarket non-upsweep exhaust recommended
• Softail Low Rider S / ST – Fits with OEM tail lights or center-mounted aftermarket lights
• All Dyna Models – Fits properly
• Indian Chief – Fits with a step-up or passenger seat
• Indian Scout / Scout Bobber – Fits with a step-up or passenger seat
• Honda Rebel / Honda Shadow – Fits properly
• Yamaha Bolt – Fits properly if rear blinkers don’t interfere
General Fit Note
The SP-1 is compatible with most cruiser-style motorcycles that have:
• A rear fender to rest on
• Enough space between blinkers and shocks to accommodate the bag
• A passenger seat that locks down over the center strap
