The center-lift design of the Extreme Max Wide Motorcycle Scissor Jack is perfect for most motorcycle maintenance needs. Equipped with an optional dolly tray for easier mobility, the jack lifts to an extended reach of 14.25" while the 15" x 9" platform holds your bike with a rubber padding that prevents scratching and adds stability. The jack is operated manually by using a 7/8" socket or wrench (sold separately). Measurements with dolly: Extended height: 14.25" Collapsed height: 4.25" Base: 15.5" x 16.5" Lifting platform: 15" x 9" Measurements without dolly: Extended height: 13.5" Collapsed height: 3.5" Base: 15" x 9" Lifting platform: 15" x 9" Not designed to lift trikes. Do not use an impact-style wrench or powered drill to raise or lower the jack.
