The Tommy Jack makes chain lubing a cinch. It is the most compact tool available to quickly raise the rear wheel. The lifting beam just slips under the bike's swing arm. When the jack's pivot lever is swung down towards the ground the rear wheel is airborne! A safety-locking pin is inserted to complete the task in 2 seconds! The motorcycle will be amazingly stable with the three way supports of the Tommy Jack, side stand and front wheel.
