I bought some at a local chopper shop and they have about a 1" rise. I'm simply not a fan of the look of straight bars so these fit the bill. Of course I flipped them upside down so they have a very slight drop, but not nearly as extreme as a clip on or clubman bar. I have a bad back.
Take a look at the stock bars on Ducati Monsters. They are very similar in all dimensions to the "European" bars on Commandos. You can pick up a good used chrome steel Monster bar on eBay for $10 or $20.
