Who it's perfect for

For those who ride a mid-range GS — F 750 GS, F 800 GS, or F 850 GS — and actually use it: travel, gravel roads, daily use. A stationary fall or a low-speed slide costs much more in crankcases and plastics than an engine guard, and the KN5129 is the specific solution provided by the Kappa catalog for these motorcycles. Those who prefer the aesthetics of exposed steel can opt for the stainless steel version KN5129OX.
