My Quota, with the right profiled tire, was a very good handler and had a 19" front wheel. A buddy on a 600 GXR even commented on the handling as he tried to keep up on corners. Not as flickable as my Griso or CB, but she can hang in there. The XR650L has a 21" tire and will toss with abandon into corners (tight ones, not high speed sweepers).
But this all on the street at sane and somewhat legal speeds.
I"ll second the CB500 family.
I'll agree with you that wheel size is a red herring in so much as it seems to be often blamed for a bikes slower handling characterstics. Physics, however, don't lie. There is a difference in how quickly or with how much force a larger diameter wheel will react.
The problem with the argument that a larger wheel slows steering is that it ignores the many other factors to a motorcycle's handling that include, but are not limited to:
-Frame geometry
-Steering geometry
-Suspension geometry
-Suspension setting
-Handlebar position and width
-Overall weight
-Front to rear weight bias
-Tire width
-Tire pressure
-Tire type/tread pattern/tread wear
There are only a handful of bikes available in relatively similar configurations other than wheel size:
-Suzuki DRZ400-S (21") and DRZ400-SM (17")
-Triumph Tiger XC (21") and XR (19")
-Aprilia Caponard Rally (19") and Caponard Travel Pack (17")
I have yet to see a comparison of the two configurations that focus on how the front wheel size affects handlings. Instead, moto-journalists end up comparing competitive bikes which, per my list of factors above, shows how relatively meaningless such a comparison is. I've read multiple comparison articles and the DL650 always gets compared to the Versys 650 and called out for slower handling due to that 19" wheel. Never mind the Versys is a few inches shorter between the axles. Same goes for comparing the DL1000 and the new Versys 1000 or FJ-09.
The reason I brought up the wheel size in my comment was I assuming the comment about the V-strom handling was based on the often quoted tire size difference, but also because physics are on that side of the argument, even if it makes a smaller difference than other factors. Ironically, I ended up somewhat perpetuating the very argument we both agree is mostly bunk.
