VEVOR Motorcycle Lift, 1100 LBS Motorcycle Scissor Lift Jack with Wide Deck & Safety Pin, 3.7"-13.8" Center Hoist Crank Stand, Steel Scissor Jack for Street Bikes, Cruiser Bikes, Touring Motorcycles
There is nothing to fix it separately. If the center of gravity is stable, it will not fall over. If you want to keep it stable after removing the front wheel, you can use a motorcycle stand.
The one below is with wheels: https://www.vevor.com/hydraulic-motorcycle-hoist-c_10310/vevor-motorcycle-lift-1100-lbs-motorcycle-lift-atv-scissor-lift-jack-with-dolly-hand-crank-center-hoist-crank-stand-with-wide-deck-tool-tray-for-street-bikes-cruiser-bikes-touring-motorcycles-p_010464588471.
Fold the center lift stand to a 3.7-inch height for compact storage and transport. The powder-coated finish resists oil, grease, and rust, making the motorcycle scissor jack easy to clean and store in your garage or repair shop.
