So I ordered the offset shifter from Monster parts. Offset is ~1" which is great and clears the 821's massive rearsets. However, overall length is 5" and puts the toe peg way too close to the foot peg.
The shifter I had on my S2R1000 is shorter (~4.25") but the lack of offset causes it to hit the rearset.
Here is a picture of the stock setup arranged in the reverse pattern. This is as low as I can get the toe peg without binding.
Here is the non offset shifter.
Here is the offset shifter.
The ideal length for an offset shifter would be ~3.5" and IMO there should not be a downward offset, at least not to the degree of the offset shifter.
But, I'm not sure anyone even makes one yet. I certainly haven't been able to find one.
If I had welding skills, another option would be to chop 3/4" out of the non offset and weld it back together.
