Bought the TR1500 with the electric pump option and the extended ramps. The extended ramps are need for the Harley TriGlide in order to clear when driving onto the lift. I also found that my two wheelers (2014 XL1200C and 2018 XL1200X) would hit when loading. I modified the main ramp by adding holes for the extended ramps to connect as they do on the side ramps so they would lock in side by side and centered. This keeps them from sliding out of place and gives a perfect angle that allows the two wheelers to clear perfectly when loading. It also gives the ability to use your feet on them when loading to help steady and balance the bike. The lift is perfect for my needs with all my bikes now.
