Got to ride both a 107 Street Glide and a 107 Road Glide last evening. There is no valve train noise to speak of, only a muted swirling sound, the motors on both were very quiet. The exhaust is very quiet on start up and idle but when you give it some throttle the exhaust note picks up and gets louder as you twist. Going down the road the exhaust really doesn't sound bad for an emissions compliant exhaust system. The exhaust sounds pretty good when getting on it, *again, for a stock system.
I am not easily impressed from a performance stand point, but I have to say, for a "stock" out of the box new bike, I was pretty impressed with this new motor (and bike). I didn't beat it up as it's brand new and appreciated the opportunity to get an early test ride but I gave them a pretty good run. The bikes are quick, you can feel the acceleration improvement immediately and once you get up around 2700 and especially 3000 you can really feel the added torque and acceleration. The motor has a loose and quick to respond feel that I have never felt on any stock big twin motor before. In my opinion, the guys that are usually on the fence for a stage one kit will not need to even think about one now.
There was almost NO vibration, which for me I like, when I say almost none I mean very, very little.
Of course there was heat on my right leg but definitely less than the previous. I like the way they have the rear exhaust pipe tucked in close to the motor. It appears like they did most of the turn out in the exhaust port of the head instead of in the pipe, which I also like. (this is only a guess obviously)
All is based on my impressions of "stock" and based on my impressions of this 107, the 114 is going to be a home run.
Of course we need to qualify with the usual "time will tell the full story" but for right out of the box I think they knocked it out of the park.
There was no first gear clunk from either bike and very little comp / chain clunk at any time. There was a muted clunk shifting to the upper gears but 5th and 6th was very quiet as was down shifting. Finding neutral was easier than in the past, for a new bike.
I went looking for every bump I could find and found this to be the smoothest riding "Harley" (non ultra) "Stock" I have ever been on. We already know that they changed the front end and it was smooth. I know the rear shocks appear to be the previous hand adjustables but sure seamed to be an improved version, maybe they have simply re-valved or changed dampening. I didn't take time to read anything about the rears so maybe the answer is right in front of me?
I took them both to near scraping the floor boards and the bikes felt planted and I felt no need to back off whatsoever, there was a very good feeling of stability.
I didn't take time to play with any gadgets, sound system sounded good on both.
And before you think it.............. I'm no coolaid drinker, just my unbiased opinion.
