StepRamp® SR-B6 6-Step Aluminum Dirt Bike Loading Ramp for 36–44" Truck Beds

What Is the StepRamp® SR-B6?

The StepRamp® SR-B6 is the world's first 6-step aluminum dirt bike loading ramp engineered specifically for tall and lifted truck beds with 36–44" load heights. Its patent-pending design combines knurled, hi-traction stairs on one side with a rugged ramp surface on the other — delivering the easiest, safest solo dirt bike loading experience available. Say goodbye to slipping, straining, and the awkward two-person push that comes with traditional flat aluminum ramps.

Who Is It For?

The SR-B6 is built for dirt bike riders, motocross enthusiasts, and frequent haulers who use lifted or tall pickup trucks. It accommodates bikes up to full-size 450cc+ and is engineered for everyday use on trails, tracks, and job sites where a standard ramp simply doesn't cut it.
