Asslam-u-Alaikum,
Brother it creats no problem for second person as you can see in picture and it can be adjusted further backward. It comes with about 11-12 metal pieces of different design and length for installation. I bent some pieces with hammer according to my requirement and attached it at 4 points
1)- with right side bolt of seat
2)- with bolt attaching red plastic part around seat
3)- with bolt of rear steel grip
4)- at lower side, with bolt of silencer (can be seen in picture)
Only problem was right indicator, so I removed spacer from indicator
If you need more detail, I shall post pictures after uninstalling it probably at weekend. Please let me know
