I own 2 of them and a yamaha jog. The MBK is known as a zuma around here. I have one with a built motor and the other is mostly stock. My yamaha jog is smaller and lighter but the zuma is better suited for all terrain. Nice scoot
Aftermarket parts are endless and you can build quite a ripper.
But also the engine mounts on these are low, so might not work the best in a Navi. Not sure where the Navi engine mounts are.
