The harness subject is one of those that is similar to politics and oil brands. People have many different opinions and reasons that they believe in them or they dont.
One way to look at it for me is it has to be safer to wear somthing that helps me control my vehicle (not for crash safety) than to not wear anything at all. Because that is what I would have on. Nothing...
And if I slide off the road and smack a tree at 55 or 65 I had much rather have the harness I have holding me from being tossed out. It may give me whiplash or but I will take that way more than being ejected .
You will noticed in my example I used a tree... This is because if you slide into the path of a Chevy Tahoe that is coming toward you at 65 and your moving 65 I just don't think it's going to matter if you have a seat belt or a harness... You going to have a very difficult future after that impact.
We all have to remember that it's not Polaris RZR and it's not a car.... It is a motorcycle. It has no bumpers and no crush points.
Wear somthing to hold you in if you can. And if wearing a harness helps you control your Slingshot then do it.. If you have a head on it may snap your neck but ill take that chance. I'm pretty sure that when I am carving asphalt on a Ducati motorcycle and someone comes into my lane it would be way worse than what would typically happen with my harness on in the SS...
Just be as safe as your can and always watch everyone. They are out to hit you. Everyone is...
