Unless you have something else hooked up like an auxiliary USB port or something else drawing power when the bike is off 2-3 weeks should not be a problem but a $30 battery tender device will guarantee it will be fine.2021 Honda CB650R Question Would the bike start if left for 2 weeks in a garage ?
I would definitely put a battery tender on it. I use the Optimate 3. Excellent device. 2 weeks is probably fine, but there is always a slight draw when shut down, so a battery tender is a good way to keep the battery at optimal health.2021 Honda CB650R Question Would the bike start if left for 2 weeks in a garage ?
