I’m not too sure if you actually need speakers on a motorbike considering all the road noise that will interfere with your listening experience, but if you insist on picking up the View Gate VMP-300, then who am I to stop you? Just in case you’re not sure what you’re getting into, the View Gate VMP-300 motorbike speakers come with built in 15W amplifier and 25W output. Since it is powered by 12V DC, it is compatible with most bikes. Just make sure your iPod comes with a tough protective case because the biking life can be rather harsh, especially on sensitive electronics. The View Gate VMP-300 will retail for approximately $98 for a pair.
