I worked on a SR3 some time ago. It had a Kawasaki ZX 1100 engine in it which seemed to be its biggest weakness according to various bike people I spoke to in search of parts (most notably trannys, like 79TA mentioned). I am not really a bike person so I don't really know about the drivetrain portion of the car. The car itself, chassis, etc, was really easy to work on and extremely accesible since the whole body comes off. It is a pretty simple design as well so it should be a easy car to work on by yourself with limited equipment. It does require some higher grade hardware IIRC which can add up. I would think the higher costs would come from the engine depending on which model you are looking at. You could call up some bike shops and ask them what kinds of costs they would charge to rebuild, etc that engine to get a better idea as well.

All in all, they are great cars and will provide some good fun at a lower cost than some other options out there and they are damn fast.
