Yamalink: Which 2015 WR250F lowering link? 1.5" or RACE?

Question of the day: I was looking at the options that you show for a 2015 WR250FF. I am not sure what the difference is between the "RACE" and 1.5" choices. I need a link for an intermediate B level rider in hare scrambles and enduros. He just purchased the bike and is barely able to tiptoe when sitting on the seat. I would appreciate your recommendation on which one to get and availability of your recommendation. Thank you for your time and knowledge.

For a B Level racer on the redesigned 2015 WR250F the YamaLink we recommend is the Race version.
