What is a good replacement battery for my 06 WR450

My battery wont' hold a charge anymore, What is a good replacement one other then stock?

The stock Yuasa is the best battery you can get for the WR. Unfortunately battery prices have gone thru the roof this year. Even the "cheap" brands are expensive now.

Couple of thoughts:

The stock battery should last longer than a couple of years. At 4 years my stock battery is getting a little weak, but still holds a charge.

Maybe you should check the charging system on the bike to make sure its outputting well over 13 vdc at the battery, while running..

Also, if you had the stock battery on a continuous charger, and not a "smart" charger, maybe that shortened its life.
