I'm still looking for a bike, wanna get back on the saddle after a 9yr hiatus. just wondering whether my old helmet (an hjc -dot & snell approved from 12 yrs ago) still conforms to today's safety standards. it's never been in a wreck. should i toss it and buy a new one? still wear it? use as passenger helmet? or pot tulip bulbs in it and wait for spring?? appreciate any advice.
