Rob & I happen to be on a pair of ’14 Triumph Tiger 800 XC for this trip; he has several bikes. With a 200 mile range, we stop about every 3 hours for fuel & a stretch.
We have more than enough luggage each for such a brief trip. With the heat, Gerbings aren’t aboard but the Frogg Togg towel and the CamelBak are in season. The capricious weather in Great Smoky Mountains National Park dictates a few thin plastic dropcloths for night time bike covers from rain as well as toting a rain suit. Snack bars, as there’s little food on Skyline or the Dragons. Probably leave the panniers home & go topbox and mini-tankbag. Really most is electronic; GPS, GoPro, Mophie, phone and several cables & plugs.
Those engine-bar bags come to about 7 liters each, I guess, and hold alot of the space-consuming lightweight items that formerly congested the topbox; rags, the aforementioned .5mm plastic dropcloths, extra gloves, zipties, extra waterproof 24 liter bag rolled & ready, bungies, a cargo net & more.
I cut a gallon water bottle so 3/4 remained and it made a sturdy wall and floor. Now the bag retains its shape for better use. Did both bags.
Here is our route in full; over 1,600 miles. We may leave a half day early to be at Skyline Drive north entrance in the morning.
