First, upgrade to my new (to me) WR250R. Installed this lithium battery a few weeks ago and have been really happy with it. Quite a bit of weight savings and it has the restart technology (peace of mind). It's just plug and play so was super easy to install.
Thought I would share the link to the battery that worked along with a discount if it helps anyone looking to upgrade.
