Yeah I've been riding for a long time also, and I've been hurt and in the hospital twice with bike crashes. Luckily they were both slow moving accidents. I learned then (1984) that it doesn't take much to get seriously hurt quickly on a M/C.
You are right though, good clothing will help. I recall a statement the instructor made in the M/C Safety Class, jeans only last 8 feet and leather lasts 44 feet when being dragged across the asphault, which would you prefer, "Leather".
Cant stop living life though......be smart , be safe , make the best choices you can and enjoy every day..... Can't agree enough with this statement, that's why we're both still here man.
