Here are some ways I carry my stuff and electronic gear on my bikes.

I use RAM Mounts for my electronic goodies. That way I can move the gear from bike to bike and between the cars I drive.

A good place to find these mounts is:

You can see here I mount my GPS and roll-chart holder with the RAM Mount.

The RAM handlebar connectors are simple but very effective. Even after multiple drops the electronic goodies are never hurt or fall off.

I haul my stuff in a Wolfman Enduro Tank Bag on my LC4 now. Sure make it easy to grab my camera.

I use the same system on my BMW R1100GS.

I use Velcro to attach either the roll-chart holder or my radar detector to the top plate of the RAM Mount. As you can see here I use a Radar Screamer attachment to my detector so that I can hear it while riding.

The simple screamer hook-up is a snap.

Tool Case

I decided to secure my tools and first-aid kit to the bike. That way I do not have to worry as much about theft. Besides the Pelican Case is quite durable and waterproof.

Update: When riding the trails my butt kept hitting the hard bag. So I have now added the KTM tool case which is under the rear fender. I'll save the Pelican case for some long adventure.
