(Note, they actually cost MORE than the Helibars Pilot risers. He is referring to the very expensive Helibars Horizons)
They look very interesting and is twice the pullback of the Helibars Pilot (3/4"). However, the Heli's are 2" rise (claimed), not just 1 1/8" (and RAM mount/powerlet options). But the greater pullback of yours might be just what people need, more than height.
Your right, I was referring to the Horizons.
The 2" rise that they and everyone else that has a set of 2" risers claim is actually just the height of the risers themselves, not the actual amount of rise they give you. Because of the angle of the triple tree, 2 inches of riser doesn't equal 2 inches of rise because the handlebars are rising and moving towards the rider instead of going straight up. On the link I provided, I detailed how this calculates out. Before I designed my own, I was using a set of their 2" risers so I was able to use theirs to confirm this calculation.
As for the Ram Mount option, I have one coming out in the next couple weeks. CAD work just got finished on friday and I'm waiting on the quotes. Mine won't be attaching to the risers, but a location much more fitting for mounting a GPS...actually, it will be in any of 6 locations I'll announce when I have finished product in hand. Let's just say it'll put the GPS directly in line of sight.
