just had an off bout 30min ago and am very annoyed with myself....although i am 100% fine and am grateful for it! been riding for bout 2 months now and i usually ride at night after work. today is my 3rd day ride cause i got today off work, beautiful day, riding, sweet, having fun. Then i enter a small quiet street with no cars around so i wanna do a U-turn. Because i'm only going at 10km/h my bars are turned and i'm not leaning......that's when i see a massive deep pothole so what does this idiot do?? i hit the front brake and yes the bike topples over and unfortunately its made alittle worse as its a steep downhill. after my 2 second slide my cb250's right indicator is busted, foot rest bent, mirror bent, tacho displaced. minor stuff. what i want to know is since i was thrown forwards my left chin hit the floor. It wasn't that hard and all i can see is a few scrapes on the left chin of my arai. the visor is fine. now even though i was going slow, it was downhill and so there was an impact..........should i replace this helmet??? the chin area is the only part which touched the ground. i dunno if because its a thinner area if its affected the integrity of helmet as a whole? thanks for any comments!
