This is supposed to give the guy some good insights and not trash bikes. Althought TheMechanic is DEAD ON on Aprilias and Duc LOL!!!!.
Ok so a bit less trashy advice. I am an LT rider, I also used to have an RS (03 18K miles) when the RS was sold the I wanted something powerfull, less complicated than the old K motor, lighter and more nimble I started looking around, here are the bikes I considered and tested.
Buell XV12S (The strangest riding position I have ever been on, noisy, clanky, everything was clanky).
Duc Monster (Great Bike, lots of grunt, Ducs are like old 2 cycle Yamahas they require CONSTANT messing with, I don't think their valves are made out of spagetthi, I think they are made out of RICE PAPER... LOL) I HATE chain maintenance
K1200R (Loved the bike, the looks, the power, the nice BMW confort touches that we BMW owners are use to. Miss the cruise Control, got spoiled by my LT and RS). Unfortunately while test riding the R I caught a downpour and my legs and shoes were soaked in 10 seconds, before my chest and back. So the lack of a fairing kind of turned me off, oh yeah the SO did not care for all the "exposed mechanics" as she called.
Triumph Speed Triple (Nice Bike I cannot get used to those double headlights the Hinkley boys like to use, it is very UGLY. I HATE chain maintenance
Triumph Sprint ST. (Super Nice bike, was actually second place on my list, saddle bags and Top Trunk were going to come in free with the price of the bike, some special Triumph was or still is running. I did not like the heat that it comes from the bike in stop light around your legs, by the time I returned from my test drive the "omelet was ready" LOL. I HATE chain maintenance
Busa. Unconfortable, terrible fit and finish, ugly colors this year, what happen with the nice blue and white or black and red?. Did I mentioned before I HATE chain maintenance.
Finally the bike I bought the K1200S. Granite Gray, BMW Sport Saddle Bags. ESA, Trip Computer, I absolutely love this bike, the riding position is a bit more sporty than the RS was BUT, here is the BUT, the RS had a long reach for the bars making it hard to straighten your back, the S allows you to ride like a crotch rocket and or straight your back and get lots of the weight off your writst. I LOVE IT. The seat is very good, I am considering a touring windscreen since I am 6.1 I am getting BUGs BLAST on my helmet. The power is plain and simple STUPID FAST.
Gripes: Yeah I have two:
Bike HATES to be in bumper to bumper traffic and slow moving lines bike likes to be rev hard.
Clunkiness when shifting from 1st to 2nd and 2nd to 3rd. I have been told it will get better, with 1500 miles on mine it has NOT, and its plain and simple embarrasing sometimes all the noise it makes when shift.
My 5 cents.
