“One of the bluetooth motorcycle speakers that come to mind is this product from Shark. It has a continuous power handling of about 65W and a maximum wattage of 150.
“The speakers are waterproof although the peripherals are not, so you have to cover them with some plastic.
“You can also play songs through it using an SD card, flash drive, 3.5 mm compatible music devices, and Bluetooth.
“The downside of this product though is its short cables, especially for the remote. But that should not be much of a problem because it also comes with a wireless one.”
There are plenty of Bluetooth motorcycle speakers now on the market from as low as $100 with 600 watts of power, such as these from Boss. Just make sure if you put them on the handlebars they do not obscure the instruments or your controls.
She also suggests that if you are adding speakers to your motorcycle or upgrading the original speakers on your tourer, you should go “loud”.
“The best motorcycle speakers should have at least 300 watts RMS,” she says.
