I ran a pair of Avon Distanzias on my old BMW (1972 R60/5). That bike wasn't any good on the dirt, but the tires were great. I'm wondering if anyone has found good dual sport tires that work on the stock rims, etc. of the Seca II. Despite the poor placement of the headers and the oil filter, I take my Seca Tourer off road in Death Valley, Moab, etc., but always on Avon Roadriders, or Michelin Macadam.
