I recently had a slide off my bike on the highway, came out with limited damage on my body, only burn scraps on my right hip and right elbow. god bless!! the bike is gone. So I've been accessing the damages on my protective gear, my helmet's gone, with 2 small patch of scratches. the knuckles of the gloves are scratched, but barable. The main thing i wanna ask is. do i need a new jacket as well. Its the alpine star RC-1, with half a mm deep scrapes on the surface of the leather along the left shoulder area, didn't punch through, i've checked all the shoulder guards and arm guards on it, there's no cracks on it. is it safe for me to keep wearing it when i hop onto my next bike? and another thing is, how long till i should (in this case, anyone) replace protective gears from new, do they have a time period before they won't give as much protection as it should?
