I hate to hear of anyone dying , let alone on the highway, and especially on a bike.
Don't know what got in Bruce's' head to pass the trailer under circumstances listed.
I can only surmise that he grew impatient and started to pass just as the guy pulling the trailer decided to turn and you know Harleys aren't that fast so he may have just got clipped. No helmet , don't get me started.
Sounds like the World lost one of the " Good Guys." RIP Bruce.
On a side note . One of the things I like about my " R " . With all of it's quickness, it can get you into trouble .....but it can also get you away from trouble real fast.
