Crash bars might be an unnecessary weight load for such a bike. On the other hand, they do make getting the bike up much easier when (not if) you drop it. My old GS80 had them and they were very nice in that they kept the bike from damage (crushed valve covers are bad) and made it very easy to pick up. My 1200 Super Tenere would need a crane without them. If you are on your own you must be able to pick up the bike (with your back to the bike using your legs, not facing it wrecking discs). As to tools, take what you know how to use. If you are no mechanic, 5kg of tools will not be of much use. With older bikes I always routed spare cables for everything (heat-shrinked at the ends and nylon tied out of the way). With a relatively new bike you will likely have few problems (I once had to ride a 72 Triumph Tiger about 160 mi through desert roads using a broken throttle cable looped over my right leg, ( just push leg out to accelerate...),this added a measure of challenge and joy to the day...) This taught me the value of spares, but new cables are better, stronger, more waterproof and you are on a Honda (reliability is thy middle name). Buy a good patch kit (not synthetic rubber), use no slime, and get valve stem remover caps for both tires and carry a spare tube (or two). Practice pulling the wheel and tube prior to the trip (sitting in mud with a flat as night sets in is no time to learn). Enjoy your trip!
