I've been a BMW rider for many years. I put 20,000 miles on my '04 RT. I had an 1100 GS before that, and put 40,000 miles on it. I just switched from the '04 1150 RT to an '06 FJR. The FJR is without a doubt, fabulous. I test rode the new BMW R1200 RT, and it is far superior to the 1150 RT. I considered trading in my '04 for a new RT, but the FJR won. The BMW pops on deceleration, and pings when it's hot. It uses oil. I had to carry a quart in my saddle bag all the time. It requires premium fule. It's hard to start and runs rough until it warms up.
The FJR is smooth as silk, starts right up, runs like a top. The FJR is much better at really slow speeds, like walking speed.
Obviously, the FJR has much more power. After riding the FJR, when I get back on my RT, it feels anemic, and I feel like I really have to wring out the engine to get any power from it.
I think the BMW wins at comfort. I love the BMW suspension. You can be leaned way over on a twisty bumpy road, and no matter how rough the road, the BMW holds its line and really insulates the rider from the bumps. On the FJR, I have to squeeze the tank with my knees, and I feel the road a lot more. But it does hold its line and never wanders.
The FJR is a somewhat rougher ride. Maybe part of that is due to the fact that it has a lower profile rear tire.
The BMW RT wind and weather protection is superior to the FJR. I was happy with the stock BMW screen, and I'll likely be purchasing an aftermarket screen for the FJR.
The brakes are comparable on both bikes. That says a lot for the FJR brakes, because I love the BMW brakes. You just have to squeeze a bit harder on the FJR.
I experienced some wrist tingling on the FJR on my first ride. But now I don't notice it at all. I think it has to do with the relative tightness of the throttle spring, not with forward lean or weight on the wrists. I find if I squeeze the tank with my knees, and relax my arms, it's really comfortable. I've got long arms so I don't lean forward too much, but the FJR does have more of a sporty forward-riding position than the BMW. For me, I like the FJR riding position, and it's very comfortable on my back.
I've never ridden sport bikes, so for me the FJR is my first sport bike. For now, I'm loving it. The BMW was just a little too boring. The FJR is a little bit naughty, and naughty is nice! :lol:
