USA bikes don't have "off". Sicass Racing light switch for the EXC is plug & play and gives you more room on the bars to cut them or run the levers in a better position.
The "quick" swap will be a PITA due to the cross brace. Unbolting and reattaching it to the oil tank are a chore. The Safari has the same ergos as stock so I say just live with it. Of course, I'm thinking of swapping back to stock as I never know how much I have in the Safari and end up carrying 8g when I need only 4.
I think the SMR has the same dash??? I ran a power outlet thru that, sorry don't have the bike anymore and my SE has no dash.
