Ok, newbie question....will the 45 WL seat post fit a UL frame?? I can get a 45 H Duty seat post for nearly half what a one costs from V-Twin. The H Duty spring sets cost nearly what the 45 seat plunger set does too.
Sure it will fit in there. With lots or room to spare as it is considerbly smaller than the Big Twin seat post.
Will it function properly? NO!
