All of my exchange seats or custom seats are $389.00. I generally have DRZ and DR seats in stock ready to exchange and I would need your seat for a custom build for around 7 - 10 days to have it upgraded. The DRZ seats are upgraded with a custom foam in similar dimensions to the big brand names with a new cover made to order. I normally have both the standard and gripper finish in stock. The DRZ seat is around 40 MM lower in height with the DR seat the standard height. I can have your DRZ seat made into an adventure seat at the standard height at no extra cost but I do need if for 7 - 10 days. Exchange DRZ and DR seats need to have a good base with all mounting rubbers intact and the pan not damaged. The condition of the cover is not important as it goes in the bin. If you are in Perth you can do a drop off and pick up in Hillarys. I can also post seats for $25.00 for post and handling. If you want an exchange seat and cant be without a seat I can post mine first with an extra $100.00 bond which I refund once I receive your seat and inspect t it for condition. If you have any more questions, then simply send me a message or pick up the phone for a chat.
