No experience of the SR, but I ran the Suzuki equivalent, the GN250 as a commutter for 5 years and it was pretty good. Same layout, single 4 stroke engine, 'cruiser' styling. The GN was good for about 65mph flat out ( 80 when new but this one wasn't!) about 70+ mpg, not quick but handled well so you could go flat out everywhere. Very reliable but tended to eat back tires and cheap chains ( considering it was only a 16bhp 250) and the GN had an appetite for oil. Good little bike and I imagine the SR would be fairly similar. Nice torquey engine would have been good in a trail bike rolling chassis.
