I have been a full time motorcycle commuter most of my adult life.
The bikes I owned that were primarily used for commuting.
2 Honda CB750's
Yamaha V-Star 650 classic
And for the past 5 years, a Ural patrol.
Sticking to 2 wheelers, I have to give the nod to the V-Star.
Not as much protection or carrying capacity as a tour or sport tour bike, but with a wind screen and bags, its still better than average
Fairly low in the power and speed department, but delivers its power how and where you need it in real world conditions.
Not as nimble as a dual sport or sportbike, but very easy to ride in stop and go traffic, and other slow, tight conditions.
The ergos are fairly neutral for a cruiser and quite comfortable for a few hours. .
I don't really care for cruisers, its a very uninspiring bike to ride recreationally, but they can be had dirt cheap, will take mishaps with little consequence, is unlikely to be stolen, has shaft drive, requires minimal maintenance, and is very reliable
I haven't ridden it in 5 years, but still have it as backup transportation because it made such a good commuter.
