This would be fairly easy to do permanently. The grommets on the bottom of the headlight units line up. You would just have to do some wiring to run both bulbs on the 900 and make some brackets.
I lifted my headlight and meter gauge so couldn't resist seeing whats involved for this.
If your pic is tilted far back as possible hitting meter gauge
Might need tilt back more to match designed angle (beam)
If i'm even looking at the right bike ?
There bottom pin mount for that light bolts to triple just like ours (doable)
With there top mount holes a 90* bracket to or side mount holes probably doable
H7 stock bulbs at 55 watt each (2), so switch to LEDS
dont see any wiring show stoppers
Headlight assembly (no meter gauge) new LENS-COMP 23007-0210 Price: $471.89
Ebay right now $266 without upper faring
And now that you got me all worked up, i got to go find something to change up.
