6'3" 297lbs It depends on how long your inseam is actually, i have a little shorter 32" inseam for my height longer torso.
You have long legs need a little height in the seat to get a good leg position.
Other than that i fit just right, My Triumph Tiger 1050 was about the same.
Take up Jeff's offer and try his bike in the high position.
You may like it.
Love Goldwings but not the 1800 models.
They tend to be built for shorter Pilots/Weeble's.
Even with a higher seat i was disappointed, nothing like my old 1100GL.
My friend came up with the name Weeble's because the smaller Wing riders and passengers with all that bright (see me?) gear load on look like the old Weeble's Wobble but they don't fall down toy.
No bike is the perfect bike, but this one convinced me it's close enough out of many bikes I've owned.
It has just enough of does what you need and feel and comfortable just enough to put a smile on your face and without the same Quad cylinder Ho Hum.
Sort of like a Triple.
It's no Goldwing but it will go places the Wing wont and with much more easy access to maintenance locations.
Air filter under the tank not buried under the front dashboard, 40 minutes compared to two+ hours like my friends 2013 Wing we did.
It's like a Jeep on two wheels IMO.
