Lifted my 550+ LB Pan America for two days while I changed the tires. I used a piece of wood in between the jack and the engine. I was confident in its ability to raise the bike and hold it based on how solid it felt and the safety pin.
For the price, it's all you could ask for. I dinged the features rating due to the cranking handle being too easy to pop off. This is also why the "easy to use" and "quality" ratings got a 4/5.
