'97 was the only year that Yamaha put the ProAction in the Vmax-4, so these measurements will be more accurate than taking them from another sled with a ProAction and trying to adapt them. When I did my ProAction, WildMax hadn't posted this yet. I contacted another member who had a Vmax-4 and an RX-1 and asked him if he could take the measurements from the ProAction on the RX-1 and he sent me a boatload of pictures with measurements. It was virtually the same as what WildMax posted in the pictures above.
