That's an interesting rig. I seem to recall the M2 somewhere, probably from one of the camping mags, but I don't think I have ever seen one. Thanks.
The one thing I like about the Coleman 533 Sportster is the fact that it can safely burn Coleman Fuel OR regular Gasoline. I've run Gas in it many times with no issues because it was designed as a dual fuel stove. One of my camping buddies in the past swore by it because he'd just siphon gas out of his bike's tank into the 533 at camp and never have to worry about fuel.
This is not a big stove, so I take it when camping on my Triumph. But when I camp with my Honda (smaller bags) it's just too large for the smaller Honda so I go with the smaller alcohol stove I spec'd in the list.
As a bonus, the Coleman happens to fit perfectly in a Folgers Plastic Coffee can, like the can was actually made to house the stove. It's amazing, actually - a truly custom fit. And I drink Folgers, so I have a lifetime supply of stove cases.
