I've had good experiences with Hagon shocks on other bikes, so I sent an inquiry to their sales department about appropriate shocks for the NF since I couldn't find the NF listed in their product applications information.
Hagon responded that their records indicate an extended length of 320mm for civilian bikes and 330mm for military bikes.
Per my earlier post, my NF Military came with non-stock shocks. These have an extended length of ~330mm. Even after installing correctly sized tires (3.25-18 front, 3.5-18 rear), my bike rests somewhat lightly on the centerstand - - - which makes me think that the rear shock length is slightly too long.
Any thoughts? I don't think a shock length of 320mm vs. 330mm will noticeably affect the handling, and the shorter civilian shocks might help to better balance the bike on the centerstand.
