I had the Monotube kit installed last week and WOW!!! What an upgrade over the oem springs. The biggest difference, or should I say improvement is no more front brake dive. It gives you way more controll and stability when coming to a sudden stop and you find yourself using your front brake alot more than you use to. Bumps dont even feel them, way smoother and not as harsh as stock. I put the standard kit in (part#31-2500) with both c-clips in. Im a little big boned at 260lbs and the kit is perfect. Cant imagine riding a glide without them. Im also waiting for thier new 944's to be released sometime soon and am going throw those bad boys on the rear and have one sweet handling machine. I say if any of you guys are thinking about putting the monotube kit in, stop thinking and do it.
