Kewlmetal risers is what you just described...My wife checked out an '09 Spyder at the local dealer today. Since we have to sell a bike first, I expect she'll probably be getting a 2010 (RS) model. She's an experienced rider and knows what position she's comfortable in. We've had to change seats, handlebars and foot pegs / boards on pretty much all of her bikes over the years. First thing she noticed on the Spyder is the handlebar issue. She feels she'd need to not only have the grips UP 2" (which seems easy enough with risers) but will also need to come BACK about 2". Do any of the risers / handlebars on the market bring the grips closer to the rider?

Depending on the extent of the modification you may get into haing to extend some of the cables though.
