The Lightning version doesn't fit on my 09. The mount is too far above the bolt that the steering head rotates on, causing the arm to be too short when turning left or right. This also has the affect of making the mount to the frame to short.
I've discussed this with Randy from GPR and he said they need a triple tree (top only) from a 08+ Ulysses to get the correct dimensions to build a steering mount for the GPR that fits.
The 06-07 has a different triple clamp design.
2008 Model Year changes
New 47mm front forks replace the previous 43 mm forks. Secured with a new triple clamp design, this new front end improves the torsional rigidity of the entire chassis. Fork flex is reduced during hard braking for improved stability and feedback.
Steering sweep lock-to-lock is increased to 74 degrees from 54 degrees to reduce the turning radius in off-road low-speed maneuvers. New off-set triple clamps maintain the 23.5 degree rake and 4.8 inch trail.
