Jack
 

I have been using the Sears motorcycle jack for years with great success on a 900 lb touring bike. The secret to success is to find the proper balance point on the bike and load it consistantly. Also, after bike is slightly raised and positioned in garage, pump it up to the locking position and remove the weight from the hydraulic cylinder for storage. When lowering, lower very slowly and hold the bike handlebars securely to transfer weight to the jiffy stand. Be very careful that the jiffy stand is in the lock position and always do this on very level garage floor. My bikes are never on the ground unless I am riding them.

I bought one and took it back. Rolled my Road Glide Ultra onto it and found it wasn't as easy to move around the garage floor as I thought. It also was so easy to get it off the dolley.
