They won't hold as much as the wolfmans but they fit very well on the Bonnies. Saw them on Hedges bike and bought a set for the R3 but decided to return them and get larger bags as I'm planning on doing more camping and will need the extra space. Went with bags from Roadgear and though I'm not crazy about em I'm gonna keep em.
