This thing is a total piece of junk. Straight from china it took longer to unwrap plastic coating off of pieces than to assemble. I new right away it was not going to work. I tried to pick up my 2008 F8 and the thing twisted up like a pretzel. Welds broke and the thing is just a useless twisted up piece of metal. I was going to call and send back, but not worth my time and hassle. I'm going to weld all joints and hope this thing works, if not I'll scrap it and but a good one. Folks do not buy this, it has a great price but will not lift a normal sized sled with out twisting or breaking. Dennis Kirk should be ashamed to sell junk like this, and I will think twice before ordering anything else from them.
I should have listened to the other reviews. This dolly sells cheaper than others and there's a reason why. The back strap broke before I ever moved the sled. Once I rigged up my own strap, the main tube of the frame twisted and snapped as soon as I started to lift the sled. This isn't a big mountain sled or a heavy old triple, just a twin 600. I am very disappointed and though I did not expect a top of the line dolly, I had hoped to actually lift and move one sled before it broke beyond useable condition. I would not recommend this dolly to a friend, enemy, or total stranger. Do yourself a favor and spend a little more and maybe get a dolly that will actually lift and move a sled.
Move your sleds with little effort. This is not recommended for heavy 4-stroke machines. Everything has a purpose...this dolly is suited great for lighter sleds, but can more bigger machines in a pinch!
