Hello All,

I bought an 883 Iron in August of 2014. I had not ridden a motorcycle in almost 30 years. I got my license and tried to go everywhere I could, but had challenges on the freeway and highways when reaching 55+ mph. The Iron would vibrate a lot and felt like it was "straining".

I recently test drove a Street Bob. Even though it was cold and I was exposed in my mesh jacket, I took it on the freeway and it was beautiful! None of the vibrations of my 883. I could also feel the raw power of the bigger engine and 6 speed transmission. I also test drove a Softail Slim, but liked the ride of the Street Bob better. I bought a denim-black Street Bob and love it. Whenever I ride, I purposely try and find a freeway.

My questions are:

1. If I had done an 883 to 1200 conversion, what differences could I have expected?

2. If I had gotten a 1200 sporty right off the bat, would that have made a difference?

Thanks in advance for your comments.

The Dyna Street Bob has a rubber mounted motor to isolate the vibrations.

Similarly, the Softail has a counterbalanced "B" motor to also isolate vibrations.


1) You would have more power obviously, but the gearing would still make it a high revving motor at highway speeds unless you changed the front drive sprocket to a 38 tooth 1200 primary sprocket vs the 883's 34 tooth front primary sprocket.


2) By going with a 1200 off the bat, your RPMs at highway speed would have dropped by ~600 RPM


Of course, with a BigTwin, the RPM drop at highway speed is more than double than the difference between 883 and 1200.

Kainam said it all. And very well

Sounds like you have found what you can love so just ride. The big engines are fantastic. IMO

There have been a lot of disappointed sporty riders once they experience a big Harley. I love a sportster, but not on the highway.

It also depends on the year your sporty was. If it was pre 2004 it was rigid mounted; which means a lot more vibrations. I have a 1200c and ride my dad's road king regularly but enjoy my sporty more. It's more nimble and I am totally comfortable with it on the highway. Ultimately it depends on your preference.

His would have been post 2004, being a 883 Iron... but good point.
