I mentioned in Motojournalism Book Two that having quick access to your camera gear is key. You're gonna miss a ton of great photos if it's a hassle to get your camera out.
Gus from Florida sent me a few shots of his tankbag setup. He's found a great way of keeping things safe and organized using the padded dividers of an old camera bag:
"I bought a wolfman tank bag, gutted one of my lowepro camera bags and used it's dividers to turn the wolfman bag into a motorcycle-camera-bag. The bottom is padded the same as a typical camera bag is, so all I needed was the padded dividers. It worked great during our last trip where we rode from Miami to West Virginia."
Looks like it works great! One more thing you can do is attach the shoulder strap from the camera bag onto the D rings of the tankbag to make it easier to carry when you're walking around.
Here's a shot of my setup on the road: Same Wolfman Explorer bag, works perfectly on the KLR650.
I keep a sweater or scarf underneath the camera and lenses. I have the Nikkor 28mm 2.8 on the Nikon body, and the 85mm 1.8 Nikkor and 11-16 2.8 Tokina are kept in the LowePro slip-lock cases.
