What Is the StepRamp® SR-B5?
The StepRamp® SR-B5 is a 5-step aluminum dirt bike loading ramp engineered for solo loading into standard and mid-height truck beds with 30–38" load heights. Unlike flat ramps, the SR-B5 features patent-pending integrated hi-traction steps on one side and a rugged ramp surface on the other — eliminating slips, strains, and the awkward two-person push common with traditional ramps.
Who Is It For?
The SR-B5 is ideal for dirt bike riders, motocross enthusiasts, and frequent haulers. It supports bikes up to full-size 450cc+ and is built for everyday use on trails, tracks, and job sites.
Key Features
- Patent-Pending Hi-Traction Steps — Knurled stairs and ramp rungs deliver superior grip in mud, rain, or dirt for the safest, most confident loading experience available.
- Aircraft-Grade Aluminum Construction — Strong and lightweight at only 32 lbs — easy to carry, set up, and store.
- High Weight Capacity — Supports 350 lbs on the step side (walking/pushing) and 500 lbs on the ramp side — compatible with most dirt bikes including full-size 450cc+.
- Folds Flat for Storage — Folds lengthwise to a compact profile (72" unfolded) for easy transport in your truck bed or garage.
- Heavy-Duty Handle & Latch — Premium nylon/rubber carry handle and secure rubberized latch for quick, reliable setup and breakdown.
- Raised Tire Guide Edges — Built-in raised sides center your tires and prevent off-ramp slips for safer, more controlled loading.

Very happy with my new step ramp. Seemed expensive when I ordered it compared to other ramps…. But it’s really high quality, it’s worth it.
I got the 5 step for my Tacoma … if I was gonna do it again, I would get the 6 step so it would be a little less steep.
works great. It feels very secure and so much better than the narrow ramp I used to use. I have a heavier bike, a DRZ, and no problems.
If you have a truck and you load and unload alone this is the only way to go. I am 61 yrs old, the most dangerous part of riding prior to having this ramp was loading and unloading.
Thank you step ramp!
I found the Step Ramp to be of high quality; the design was excellent, very durable, and easy to use.
The ramp is awesome.
I love my ramp, and the customer service was very good,
The StepRamp 5-Step Loading Ramp has been a total game changer for me. The build quality is rock solid, and it feels way more stable than anything I've used before. What really stands out though is how easy it makes loading-no stress, no struggle, just smooth and simple every time. I honestly don't know how I managed without it.
Great ramp and very easy to load motorcycle into truck!
Ease of use and very sturdy, it lines up perfectly with my f150 and stays in place, most important
Very nice well made product. Work as advertised. Beware, it's heavy. IMO, walking up the steps is harder than it looks!
Works Great. Well-made and seems sturdy. Super easy to loading and unloading. Can easily push bike up or walk it up with motor running
I bought this 5step ramp for my son (and grandson) I'm 73 and haven't ridden for 10 years but worry about my son loading his dirt bikes into the back of his truck. They were thrilled to receive it!
By far the most incredible ramp I've ever owned. I load all my bikes even my BMW 120 RT with this.
Safest motorcycle ramp I have ever used and I've used many. The amount off control I have over the bike is amazing. I just just use clutch and throttle on bike to drive machine into truck bed while walking up the steps. I unload the bike using clutch dead engine in gear and front brake, while stepping backwards alongside. No more jumping off the tailgate while rolling bike down. No more mishaps riding bike into truck.
Even with my less than new knees, very easy to load and unload with the steps, plus I can leave it on the gate and use the steps to get in and out of the bed.
