The stock Honda XR650R handlebars are mounted fairly low and are also toed in slightly. Most riders of average or tall heights will be more comfortable with the handlebars raised. There are all sorts of ways to accomplish this, through blocks, new triple trees or bar mounts, taller bars, and also, by using the pivoting handlebar risers manufactured by ROX. They are a billet aluminum piece that allow the bars to be boosted up as well as rotated forward slightly.
For most tall riders this will be just enough of a change to make all the difference, especially when standing.
Here is a set mounted on the BRP (along with some standard aluminum riser blocks).
