WOW they are expensive. Best solutions I have is to make templates out of newspaper, cardboard, kraft paper. Take measurements and purchase car mats, which would be cheaper, and using the templates cut the mats for the cycle. You can also get carpet and stair runners from a carpet store or homecenter and cut mats out of that. How about anti fatigue or garage floor mats and cut out them.
