Anyone ever ridden a Suzuki Boulevard M109R? How would you compare it to Rocket 2.5L?

My old zx14 had a more comparable ride to the rocket i will think... at least till you hit 3 digits (i hear...)

 
The 109's are still a good choice. The fact that they haven't updated the bike means there are tons of aftermarket parts on the market compared to the rocket, and they had the time fixing small bugs from year to year making it very reliable. At the same time, I too am happy with my choice to trade in my 109 for the rocket but not because I look at it as an upgrade but more of a change in class. I don't agree with people who call the rocket a power cruiser...no...the 109 better fits that description...the rocket just like the diavel are in their own undescribable category.
 
I believe you when you say the Rocket 3R is super comfortable for you — at 5'9", it must be a great fit!
I'm 6'4", and compared to the M109R, the Rocket definitely feels smaller and more compact. M109R was a perfect fit for me, did not have to change anything on it.
But I rode 800 km on Rocket 3R this weekend over two days and didn’t have any major issues. I just feel that the foot pegs could be a few centimeters lower, and the seat could be pushed back and higher a bit — that would make it just right for me.
And as we all know, the seat on the Rocket 3R is quite hard. I don’t normally wear cycling underwear , but I used a pair with gel padding just for this 800 km trip — and the difference was noticeable. No sore butt!
So I googled later and decided to order motorcycle-specific underwear (Adventure option for 3R) from motoskiveez. Maybe someone else is dealing with the same issue and bike trousers really helped, so hope skiveez will do even better.
