There are plenty of good speaker setups out there, but don't go chasing them too hard. Speakers work by moving air. These speakers are small, so they can't move much air, but they have to fight with the wind and all the noise of a motorcycle. The only way to get really loud audio is with a fairing, big speakers and an amp. BUT, you CAN get decent audio out of small speakers, just don't expect incredible volume or bass, otherwise you'll be disappointed.
Just a heads up! I have a handlebar system too and I like it, it's the shark one (cheapie), you can hear it up to about 65-70.
