I think it would be a fundamental mistake to kill the RT line in favor of the F3 line. Even with U-Fit, the "feet forward" riding position is not for everyone.
Let me explain: I came from 30+ years of riding BMWs, so I was used to a "sport riding" position where your feet are placed directly below your hips. I bought an RT-S new in 2014. The RT's "sit up and beg," upright position (with your feet positioned more forward, under your knees) took a bit of getting used to, and I still find myself unconsciously moving my feet towards the rear of the floorboards during twisty maneuvers.
With either the sporty, BMW-like layout (as found on the GS and ST lines, BTW) or the more upright RT layout, you can still stand up on the footpegs/floorboards and use your legs like shock absorbers (as you might do when crossing some railroad tracks). This is very much like riding a horse with an English saddle; you stand up in the stirrups when the horse gets busy.
I've sat on some F-3's and noted that there's no way (for me anyway) to stand up on the pegs. This means my butt will have to absorb the bumps (and said bumps may be transferred to my spine). I hope the F3 series has a very plush seat -- otherwise, I'd be looking for an aftermarket solution PDQ!
This line of thought occurred to me when I was first thinking of getting off BMWs and I was looking at Harley (rationale: there's a Harley dealer in every town over 50 people, whereas BMW *might* have one per state). The upright position of the touring bikes was do-able, but the more extreme "feet forward" models turned me off, per the rationale above.
I mentioned all this in a previous thread, and that since got me to thinking: I believe BRP is missing out by dropping the V-twin platform and not substituting a sporty-oriented machine using the 1330 engine, with a lean-forward riding position.
So my logic goes the other way -- keep the separate RT and F3 lines, and create another one, recreating the ST riding layout. I don't think a single model will appeal to all riders, so BRP ought to have several variants to cover all the riding style preferences. I think you'd suck in more customers that way.[/QUOTEI sat on a new RT yesterday at the dealer while my F 3 was being serviced. I immediately disliked both the riding position as well as the marshmellow suspension. Some people might like them, but I'd guess they are smaller than my six foot two 280 pounds.
