On the rear yea, but it also helps get the belly higher which in some cases will help you get through stuff and well as over trees easier. I see your point about lift kit and perfex kit. I wouldn't actually do it, I was just wondering if anybody heard of it being done. Thanks for that info.Besides its the tires that give our 450s the ground clearance, the lifts etc. just allow us to run the bigger tires. If you had an IRS bike then the lifts would give you the G.C. your looking for.
