Here are just my initial thoughts after having the bike for a week and having put appx 400 miles on it (the break-in period is 600 miles before first service, then I can really open her up).
The bike is sheer power and performance, meant for the track. The reviews you have already read are correct in that regard. If the bike could speak English, it would only know one word, "GO". For an example, in 1st gear anything less than 30 mph is somewhat of "chug-a-chug" type of ride where the bike needs to go faster to get into a comfortable and smooth rate of speed/power. Never was this more obvious then on the day I took delivery down in Nashville, TN and was riding it back to Indy. As we approached Louisville we hit some bad stop and go traffic. This bike is horrible in stop and go traffic. However, when we were moving at a great clip it was perfect.
Now, I will say that I love the bike. Completely glad I decided on going with it and up to this point do not feel I have made a bad decision. I had done enough research to have confidence in my decision and knew exactly what I was getting. If you're considering this bike just be known that you are not getting the most "comfortable" ride in the supersport category of bikes. It's a very rigid suspension, which is great for feeling the road and for performance, but very uncomfortable on bumpy roads (doesn't bother me a bit). Also with the bikes power band, again, you need to get going at decent clip for the bike to settle into a smooth and desireable ride. The sound of the engine is gnarly as hell, absolutely tenacious in every part, which is one of my favorite parts. The electronics on the bike.......damn, so many options (over 100 different configurations possible) and yet they are so efficient and making sure you are confident and comfortable riding a litre bike. It's definitely a head turner, no matter where you are riding. Everywhere I go, people just stare and or stop me to discuss the bike. I went downtown to monument circle last Saturday night and as soon as I pulled up 10 people immediately stopped what they were doing and walked over to gawk and drool at the bike. No matter what people's tastes are, most agree that it looks like a MotoGP bike (which is exactly what I wanted and exactly what Yamaha was trying to accomplish).
Now, I haven't had a chance to really open her up yet being that I'm in the break-in period, but you also don't need to give it much to know that the bike is rediculously fast and advanced - no way will I ever be experienced/skilled enough to push the bike to its limits. In fact, I think it's safe to say/admit that unless you're a professional racer currently in a league/circuit (ie. AMA, etc.) neither can/will you be able to as well.
In regards to the cell phone mount, I have a RAM mount on every bike so that I can use my phone for GPS and calling if in need. I also listen to music typically when I ride. While doing so, my eyes are always on the road when riding though. It's only at stop lights that I may make changes or etc., just so much easier than having to pull it out of a pocket and rush to get what you needed done before the light turns green. And even using as GPS, a few glances here and there with enough space in front of you is not going to kill you.
To make a long story short though, the bike is AWESOME! Feel free to ask as many questions as you'd like. I'll post some pics when I finish getting the new exhaust installed hopefully by tomorrow evening or Saturday at the latest.
