The Marauder is now called the M50.
There is a review in a recent Rider magazine.
they seemed to like it.
It has the 805cc engine, which will give you better gas miliage than your other contenders.
I rode both the Mean Streak and the 1600 Classic at Americade last year and disliked the riding position of the Mean Streak.
Very much feet forward which will translate to a very sore back at our age.
I am the same height and weight and 52.
The 1600 Classic as much more comfortable if a bit heavy.
You should consider the Honda VTX1300.
I found that to be THE most comfortable of all the cruisers I have ridden.
As always take 'em for a test ride first.
Sitting on them in the showroom and taking them for a ride are two completly affairs.
I love the way the Mean Streak looks, I hated the way it rode!
I loved the ride on the Warrior, but she's gonna be a bit of a gas hog, with a very small tank. A lot of fun to ride though.
Take a ride on the Suzuki M50, and if you like it buy it! Handles well, a somewhat peppy engine, and plenty of aftermarket parts for it.
I think you'll like it.
I just picked up an 82 Wing for the wifey to feel comfy on.
I also have a 650 V-Strom, a VERY fun and versitile bike.
Good luck and let us know what you get!
