RIP
There's not much to go on, but judging by the very stock looking bike (how many of us are still using the stock exhaust after a year?), I'd guess it's a very new rider. If that's true that somehow makes it more tragic in my mind. I think it's very important we educate one another so as many of us can avoid this as possible.
I always think of EthioKnight when I read things like this. Always make me sad.
