Spring Assisted Motorcycle Slider Anyone?

Hi everyone, I am new to this forum. I have been interested in motorcycles for years but it wasn’t until recently that I started looking into purchasing one. My budget is low so I was looking into a totaled bike and fixing it up. I started visiting salvage yards and I noticed that about 50 percent of the bikes had sliders on them but the bikes were still getting damaged. I thought the whole idea of a motorcycle slider was to save your bike. What I believe people over look the fact that by adding a motorcycle slider you are GREATLY increasing the force of the fall onto one point; your slider. So I have designed a spring assisted motorcycle slider. I have researched springs and have found that I am able to mount a 400 pound spring into the slider, which I feel is plenty. I am currently building a drop testing device and have built a prototype slider with a 200 pound spring. Soon I will upload pictures of the prototype and when I’m finished testing I will upload a video of the testing taking place. The prototyped slider diameter is 2 ¾ inches I think I can make the diameter closer to 2 inches. The design is “Patent Pending” but I would love to hear suggestions and comments about the design like the mounting base or the sliding puck holding device. It seems like depending on the bike it needs a spacer or something so the mounting base can be bolted to the frame. Is that correct? Thanks for your time and happy riding.

They are actually called frame sliders because they are designed to save the frame. Bodywork is not part of the objective and outside simply dropping it, its hard to picture any kind of slider saving all the bodywork.

As you muck with the design of a slider I think you'll find that you're weakening the slider for some applications and reducing its effectiveness in the incidents at greater than 0 mph

I feel like durability might suffer from the addition of moving pieces.

Not speaking of the axial force (compression of the spring), but how would you rate its resistance to lateral force? If the slider skipped along some rough road, hit a pothole or a low curb, would the spring mechanism come undone?
