Virtually anything is fully capable, even the little 650cc "Wee Strom". Taking the advise or seeking OPINIONS from folk who either have a bias or believe they know truths....., may be an exercise in futility.
The way I look at it, you first consider your ego's need for
POWER ..., or if you will be hauling around a passenger, carrying lotsa luggage, climbing steep grades to higher altitudes, etc., thereupon deciding what size engine you need/WANT.
Then you consider 'exotic', designer name, trendy, "work horse", reliable, or if you want a brand name known to be either easily serviced and/or with national/international parts availability.
Off road, dual purpose, standard, sport touring, sport, wannabe racer?
"Barn door" wind protection, 3/4 fairing, 1/2 fairing, 1/4 fairing, bikini windshield, or naked?
"Ergos": Does it fit you with minor alterations? How long do you plan to be in the saddle? Is the seating position, handlebar position, foot peg placement where they need to be?
What do people have to offer (aside from personal opinions) with regard to reliability, servicing, known quirks, etc.?
What color do you want?
--------------------------------------------------------------
What is the comfort level?
* Handlebars can be easily bent for minor modifications, replaced, or brought up and/or back via bar-backs or risers.
* Seats are subjective, but a seat can be modified or replaced quite easily.
* Foot pegs..... are you a former cruiser cowboy, a duap purpose guy, or a racer dude? You jus' gotta acclimate.
How many miles have rode before you had to get off the bike?
* I have ridden more than 450 miles in one day from the saddle of my Bandit 1250. Sometimes with a sheepskin seat cover, sometimes without.
* Oh, you wanna know..... "before (I) get off the bike?"
Whenever I feel the need, have to get gas up, want some water/beer/JD, take a picture, or talk to the local color, in short.... whenever I WANT.
Routine maintenance, how much?
* I change my oil every 3,000-4,000 miles (or when the oil is contaminated), change my filter every other oil change.
* Lube my chain every 400+- miles, run a bunch of WD-40 over it every 2,000+- miles, clean it with Kerosene every 7,500+- miles.
* I clean (w/o water) my bike frequently to catch things that might need my attention.
* I pay attention to the factory recomended valve check/adjustment.
Is the Bandit really fit for a big guy like myself?
* It's sure gonna fit YOU better than it fits a small guy like myself!
