Your probably right Ted, the H2 is probably expensive for KHI to make and not many people have the $. The SX is more of a marketable bike and fly's the performance KHI flag to a bigger group even-though the only thing in common about the engine is it has a SC which is also different. I would like to buy an SX but I wouldn't sell my H2. Both would be good to have as they do different things.
Back to the original question, where did all the H2's go?
Another thing, it would be great if KHI made it's track only flash available, I'm sure they have one used during the bikes development. In-fact if they made the factory flash available it would be a positive marketing move rather than having owners publishing all the issues with aftermarket flashes. Those comments to some take that edge off the bike.
