Just ordered a Rickrak gas cap keeper from the states - what a great simple idea! Its a magnet with adhesive on it which you stick on the back of your gas cap. You put the cap on the key switch area when filling - no more lost caps.

In all the years I have been riding I have never ridden off without putting the fuel cap back on..I suppose if you do it a lot it might be a good idea...

Just got my package from the states - I got 2 for the price of 1! - they put an extra unit in the package for free, so I guess I have a spare handy. It works a treat. The magnet is small so it doesn't get in the way of anything, but it is also flush to the height of the handle so it works well. Very happy customer. It sticks to the ignition switch just like as advertised... I recommend it to anyone who worries about where they last left their gas cap when filling.
