Hammerhead makes offset shifter tips. The MX boots I ride in made shifting difficult with the stock lever on my 610. I got the Hammerhead tip with the most offset (20mm I think) and it's much easier to fit the clodhoppers in there. The offset the shape requires that you swing your foot outward a bit more to engage the offset portion of the tip. Very natural to do in the boots, but a slight annoyance in street shoes. The install is not a slam dunk. I don't remember for sure what was needed to make it work, but I think it required using the stock spring and drilling the lever for the larger Hammerhead pivot.
