I cut the end from the left handgrip of my RX3 to determine the diameter of the hole inside the handlebars. The hole is only 1/2-inch in diameter, and the Tusk D-Flex Handguards require a hole at least 5/8-inch in diameter. Therefore, the Tusk D-Flex handguards will not fit the stock handlebars of the RX3.
However, the D-Flex Handguards will certainly fit the Tusk Chub (1-1/8 inch) handlebars, which only cost $39.99. I mounted Tusk aluminum handlebars on my Honda XR650L, and they very nice.
The Tusk Chub handlebars are black.
