Motorcycle maintenance requires a stable platform Current stands make wheel and suspension work difficult or impossible, and are awkward for one person to use The Problem
‘Cruiser’ motorcycle jacks lift from the bottom frame rails. Sport bikes route their exhaust under the bottom of the bike. Prior Art
Primary Goals: • Create a device capable of lifting and supporting a sport bike • Mechanism cannot restrict work on the wheels or suspension • System can be operated by a single person. • Must be affordable and safe
Secondary Design Goals • The device should be light and portable • Should be adjustable to the widest possible range of motorcycle designs • Should be comfortable to use (should not require any significant physical strain) • Should allow for quick mounting and dismounting of the motorcycle on the lift
Possible Lifting Points Under Rear Under Front Frame Sliders Foot Pegs
Lifting from the front and rear was eliminated Limited clearance Few bikes could support their weight through those points Potential for severe damage Rotationally unstable when lifted Selected Points: Frame sliders and foot pegs
Possible Lifting Mechanisms Ramps “Cruiser” Jack Worm Lift Car Jack Winch or Hydraulics
Ramps would be inherently unstable during lifting Slipping loose, jamming Car jack lacks outside stabilization Internal or hoist lifting would require perfect synchronization Expense, potential for jamming Worm lifts potential for jamming Could lead to destabilization Cruiser jack has unmatched stability over entire process Somewhat bulky, could restrict access Possible Lifting Mechanisms
Our Chosen Design: Lifting at the frame sliders and foot pegs from a “cruiser jack” base
Mock Up • Issues found in small-scale mock up: • Kickstand clearance • Stability when securing lift points
