SP-1 Saddlebag / Backpack

The SP-1 is a first-of-its-kind hybrid saddlebag that converts into a backpack in under a minute. It is designed to mount securely under your passenger seat and transitions easily when you’re off the bike.

This is not just another throw-over bag, it’s a purpose-built system designed to move with you.

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.

Recommended Fitment

• Harley Softail & Dyna Street Bob – Fits with OEM tail lights or center-mounted aftermarket lights

• 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
