I have a 2002 Spirit 750 and I weigh 170, the bike scoots along just fine.My girl weighs 120, with total weight for us both is 290. Even though the 750 has more umph with just me it has plenty of horse for a first bike.I love mine.And for the money you can´t go wrong.I understand that a set of Cobra pipes will give the Spirit 9-11 more horse and sound pretty good as well.
