I've been racing 1000s and 600s for a while now. I had 4 podium finishes this past year, and consider myself a decient rider.
4 things I WONT ride without.
My Alpinestars Jacket
My Alpinestars Gloves
My Alpinestars Boots
My Arai Helmet.
Here in Columbus, we usually ride in packs, and there are several of us who "screw off" whith the wheelies, ect. I absolutely refuse to ride with or around anyone who doesnt wear a helmet. I dont want to see the mess when they go down. EVERYONE who rides a sport bike goes down. If not, they arent "riding." I had some newbie stop, and make a u-turn in front of me this summer at a local "stunt park." I was doing about 60 when I noticed him stop. I swerved left, and he proceeded to turn left in front of me. I put it down to slide, vs. hitting him upright. The bikes get their rash, but we both went home with out needing a hospital.
Sure, things like this happen when you are screwing off. But in the video, if that guy had a helmet/jacket/gloves, he wouldnt be in the hospital. He'd be on the phone explaining what happened to his insurance company.........
