Well, having spent most of my time on sportbikes, a YZF600R and an R1, I must say that the FJR is about where I would want to be.
I think that there are a myriad of bike styles out there to fit each person and personality. I am not a fan of the cruiser style bikes. I am also not a fan of chrome (nor maintaining it). So, I sold my R1 for another fast toy and I am back into bikes again. However, I wanted something a little more comfortable and something I could ride for more than 2 hours without being worn out.
Enter the FJR. I looked at everything anew. Again, out with the cruisers. Sport bikes, depending on the ergos, touring bikes, sport touring bikes and dual sports. The only thing that I could look at turned to be sport bikes. Touring bikes, like the Goldwing and 1200LT, were just too big. I am sure they are fine for other people. Dual sports didn't have the performance.
That left sport touring and sport (super sport) bikes. I looked into the ST4s, the Futura (which I don't think they make anymore), the ST1300 and the Triumph Sprint ST. The Italian's make beautiful things (like Ferrari's, Lambrogini's and Ducati's). However, they are also Divas. High maintenance. So, that threw out the Ducks.
Then I looked at the sportbikes that I could afford (Read: Insurance costs, due to speeding tickets). At $1700+ a year, it meant I wasn't able to look at everything. Plus, I was looking for something I would want to ride for a while. I looked at the VFR and others. The VFR seemed to be the closest for me. But, I decided I wanted something bigger.
I saw that the ST1300 performance wouldn't be enough for me. And I only gave passing glances to that Sprint. Good looking bike, but the ergos seemed to be more aggressive.
Enter the FJR. It smacks right towards the middle. A bigger sport bike, better ergos, good performance.
Now, I must say, for what the FJR is, it does it well. I was able to ride my FJR over 200 miles yesterday. At the end, I was cold, a little butt-sore but I didn't get the hand numbness I would get on my R1. It's not extremely comfortable, but that's ok. I can work with it. Performance wise, it's no R!. It is not nearly as flickable, doesn't accelerate as fast and is a lot heavier. It's not nearly as confidence inspiring, either. It's a solid bike.
However, after reflecting on my ride yesterday, I must say that it is about the minimum of the sportbike performance I would want. I would be relatively unhappy with a slower bike. I am glad I bought it and I am going to enjoy the hell out of it.
