16kg ride report.....did a little run in the rain today and tried to hit known rough spots and a couple of bumpy railroad crossings.....absolute perfection. Handling is unchanged compared to 18kg, but the stiffness in the ride is gone. My back is a lot happier and seat feels comfy once again on the softest setting. The 18kg was way too stiff even with a pillion rider. With all due respect to Bare and Will, I would probably recommend no more than 18kg for heavier folks and 16kg as a "standard" for everyone else.
I took Dave's advice and ordered 18kg springs. I ride at about 175lb with fairly light weight saddle bags occasionally added. Haven't installed them yet, but will do soon in the next couple of weeks.
