I got this for my 2002 Honda CBR 600 F4i. With the stock exhaust system, the speakers are great for cruising around town. The sound quality from the speakers is good, the only issue I had was with some songs on my phone which had really low sampling rates. For the highway, you need to crank it all the way up. Use voice navigation also works really well. The Android navigation will interrupt the music to give directions, then switch right back, which is very handy. Installation was a bit of work since my CBR doesn't have enough room to mount on the handlebars. I ended up mounting them on the mirrors and angling them towards me.
