Moto-House MX Pro Tip:

When switching your Yamaha YZ-F, WR, or FX to a lithium battery, remember that these cells prefer to stay above 13.2V. If you are racing in cold conditions, "wake up" the battery by turning on your lights or tapping the starter button a few times to get the current flowing before attempting a full cold start. Always use a dedicated LiFePO4 charger to maintain the cell balance during the off-season.
