pull back

[Redbird_imp]

If you want to use the ROX, take a sheet of paper and draw out a side view of the handlebar mounts by using the rise and pullback specs for the SW-Motech riser and the Genmar riser. We know they will work without changing brake and clutch lines. Now take a 2" length of something and with one end at the centerpoint of the original handlebar location, swivel it and see how it lines up with where the SW-Motech and the Genmar units place the handlebar. This should give you a good idea if the ROX riser will work without line modification.
Edit:
Ok, I just laid out the rise and pullback of the SW-Motech and Genmar risers on graph paper. The centerpoint to centerpoint distance for the SW-Motech is 1 and 1/2" and for the Genmar it's 1 and 11/16".
So...my suggestion would be to use this ROX riser:

If you discover a line reach problem with it, you can shave off the rubber antivibe bit until you can bolt the riser parts together metal to metal. That will shorten it. If necessary you could remove a bit of metal from the part that clamps to the original handlebar location and bolt back together to shorten it more. This will give you the 1 and 11/16" distance to match the Genmar if you need to get to that -- you may not need to get there though, you may find that you can get that 5/16" extra from the lines.
