IMO, fork sliders are utterly useless. The bottom of the forks will never touch the ground since the front wheel will act as the pivot. If you lay a bike on it's side, the major contact points are the bar ends, muffler, tank, mirrors, and widest part of the upper fairing. The fork tubes won't be touched.
If you have a highspeed get-off where the bike is tumbling, spinning, and sliding, the fork tubes still won't likely be damaged just from sliding. And there's no way I'd want fork sliders sticking out that could snag on something and yank the wheels and bars to one side. That's a recipe for an airborne bike.
I'm of the opinion that sliders in general are meant for tip-overs, not highspeed slides. Certain ones will help mitigate some damage, but don't be fooled that equipping your ride with protruding plastic all over it is going to be effective. Stick to case savers on the engine and maybe some tank or bar sliders. And don't drop your ride.
