The SV650S fork tubes are vulnerable to damage from rocks and dirt leading to seals leaking. My
first choice for protection would be to install gaiters. However, there's only 123mm space
from the dust seal to the lower triple clamp, and the claimed travel is
120mm. I didn't see how any gaiter could compress to that degree.
Second choice is fork protectors. And I (frugally) still had a couple of fork
protectors fermenting the basement, Concours parts left over from the
gaiter
install.
The SV650S fork sliders measure 59mm OD, and the Concours protectors
are 62mm ID. Furthermore, they have little nubs inside related to
fitting the Concours sliders.
So a bit of sandpaper removed the nubs,
and cutting a slot allowed reducing the diameter. I hacksawed
about 14mm out of the back, compressed into a smaller circle (about
59mm), and used a shot of heat gun to get them to stay in this new
shape.
To fasten the protectors, I used some 3M Molding Tape (used to stick
decorative strips on cars) left over from the Concours Fenda Extenda
install. Applied a couple of strips to the inside each fork protector
and stuck it onto the fork slider. It gradually becomes almost
permanent.
So far they're on solid. Net cost, free!
