This is a DIY kit that you fit yourself. The kit comes complete with a lowered custom adventure foam and is going to make your life much more comfortable. It is just the right density and shape to provide comfort for a big day out. If you are a bit on the short side, it will also make touching the ground much easier. it also has a new custom cover made by my local trimmer and a water protection membrane as well. You simply remove your old cover and peel off the foam. Drop the new foam in place, add the plastic and the new cover and then stapple the cover in place and ready to ride. Postage for this product is $25.00 anywhere in Australia.
