Boy Howdy, I agree with Thrasher! Think about it? There is a reason why no one is allowed on the track unless they have full leathers, either a suit or zip together pants and jacket!
I won't go off on why you should wear good gear but,,,,,,,,,,,,,, I have a nurse friend in Yakima, Washington who had a rider come in a number of years ago who had gone down wearing a helmet, leather jacket and jeans. She told me he was fine from the waist up, not a scratch,,,,,,,, however, from the waist down, he had hardly any skin left. Ground it down into the meat on most of his lower body. She said while they were trying to clean the dirt and gravel out of his wounded ass, he woke up the whole place with his screams!
In my humble opinion, "Don't buy any mods for your bike until you buy GOOD riding gear"! If you fall off your scooter at 150 mph wearing jeans it will be UGLY, and it will make little difference whether you have on shorts or dragin jeans.! How many of you are guilty of high speed with jeans? Every now and then I get some guy wearing jeans and tennis shoes wanting to play with me and I never bite. Just wouldn't want to spoil my lunch if he goes down?
