Please bear in mind, that with the forward controls, your right leg is always close to the exhaust manifold and riding in a hot country like Spain, you will have a hot leg
........ Not so with the mid controls.
The engine is quite wide so your legs & feet tend to go out at an angle rather than on a more narrow engined bike, like a Harley V-twin configuration. This means that that (in my opinion) the ergonomics for the feet forward configuration are not the best. When I tried the GT my feet always seemed to want to move out towards the end of the foot pegs, so I think that I would have some leg strain on a long ride.
Just some more factors to consider......it's best to check for yourself with a test ride. That's why I would say the R is the safe bet, if you can't try both in order to compare.
