Just returned back from a 3 day 1100 mi jaunt to Back of Dragon (Va) and Dragon Slayer 160 (Va/Ky). These are my impressions of seat, gps, and wind deflector.
Corbin seat: saddle time Monday 7.5 hr, Tues 7.5hr, Wed 8.5 hrs. Without a doubt the most comfortable seat I’ve ever had over 54 yrs of riding. No butt burn, soreness, or back pain. For anything over 150 mi. This saddle will be on the bike. Still think it looks bulky. Still a great buy IMO.
Zumo: worked well until deep in mountains then it kept routing me in circles using twisty routing. Up in the air still about purchase,think a cheap throw-away phone may have been a better option.
Hozen Wind Deflector: worked well on low settings tilted forward till about 65-70 mph then I raised it half way. Cut out buffeting and wind noise to a decent level, no earplugs needed. It took all the bug hits and the whole trip not one bug splat on helmet face shield. Looks kinda funny, but Great buy for 25 bucks.
BTW: I loved 160 Slayer into Lynch Ky, road clean, fast as you want to go, and little to no traffic. Back of Dragon ok, some gravel on road, but high speed limits and little traffic. IMO both better than Tail of Dragon mainly for lack of LEO’s, traffic, and much higher speed limits.
