1200+ miles of dual-sporting, off-roading, supermotoing (sort of)...one of the dual-sports was 500+ Miles of Oregon Backcountry and probably 80+ of it were highway speeds (not all at once)...the dual-sported 05 FE650e didnt miss a beat...and since then has had sportsman tires on it and ran at the local supermoto track as well as off-road rides. Also, 8 of the last nine Bergs we've sold have been dual-sported for customers. Just oil change and do your 10 hour valve adjust/check and keep on riding. The factory stuff minus a few items make awesome dual-sport kits and by the time your done, i'ts cheaper, lighter and more reliable than the aftermarket dual-sport kits.
