I think the "single downtube" frame on the VL is the key to it's great handling....that and tall wheels, it's the same with the WL, and 18" wheels, only the VL has the power on tap.
Has anyone ever seen "Rosco" (the skinny guy with the long beard and patch jeans)? He rides that '33 VLD, as his daily rider, and has been featured in books, magazines, interviews in Sturgis and Daytona, that are seen on TV? He lives locally here in west Michigan. We did a motor rebuild for him a couple years ago, right before he took off riding it to Sturgis, and parts beyond. Well he came back with over 3800 miles on it, and joked about using like 4 gallons of oil, and claims his trip was so trouble free, he didn't even have to look at his spark plugs. Granted, he's been riding it a while. But I think the point is that when your VL is "dialed in" they are "good to go"!
