Re: Hello from an F800GT rider
I had an 2013 F800GT before the 2014 R1200RT.
You will only notice the extra weight when pushing the bike with your feet (backing up, etc.). Once you are rolling it is actually a better balanced bike than the F8GT so I find it easier to handle in low speed maneuvering.
I mainly switched due to the extreme heat I was getting in my inner thigh and crotch area when temps got above about 80. But also because I just never got comfortable riding the bike much above 65 mph which of course made much interstate riding a bad experience for me.
Heat coming from the engine on the R12RT is not an issue at all even at temps in the 90s. And at highway speeds, it is an order of magnitude better in terms of ride quality and comfort. At speeds above 65-70 the F8GT was a handful but the R12RT seems to hit its stride at 70-80 and will cruise all day long with no rider discomfort. I do not give a 2nd thought to getting on the interstate with the R12RT but avoided it at all costs on the F8GT.
And then we have the creature comforts: Electric windshield, cruise control, better fairing, better seat (heated option), better lights, better brakes, better suspension, better power and power delivery. The bike is smoother, faster and more comfortable overall. A radio is even optional.
I live in the suburbs of Atlanta and have done inner City riding (downtown Atlanta), suburban riding, country roads, mountain roads, congested freeways - just about every type of riding there is - and the R12RT is great in all of those situations: It is one fantastic motorcycle.
Yes, you will feel the extra weight when stopped and you do have to be a tad more careful where you park but even when I have gotten into situations where I could have dropped the bike, I didn't because of the great balance: I have been able to "muscle" the bike back upright before it went all the way over.
As for negatives........Only one: The gearbox is a little 'clunkier' compared to the F8GT but I rarely miss a gear on the R12RT whereas I frequently missed gears on the F8GT.
You will also not have to deal with that goofy gas tank like you have on the F8GT where you don't know how much gas you have until you hit 1/2 tank.
