how to stop joints being springy

I'm trying to make a motorcycle. I've added several RigidBodys and am trying to connect them with HingeJoints and SliderJoints. But when I play the project it's like the joints are made of rubber bands, not constrained to turning about the axes or sliding in the direction they're supposed to. I've tried adjusting the settings for the various joints but they don't seem to do anything. Is this broken or am I doing something wrong?

I've tried searching, found a few other similar questions that hadn't been answered. I haven't been able to find any tutorials on using 3d joints.
Here's a copy of my project if it helps:

    BTV haven't VehicleBody/VehicleWheel worked for you?

  • Thanks for your reply. I hadn't tried it, I assumed it was for 4 wheeled vehicles only. I've just done some experiments and the bike holds together and suspension seems to work but the tyres don't have enough friction and there's none of the self stabilising effects of the steering angle and gyroscopic forces so it's impossible (for me at least) to control.
    Here's the file for anyone interested:

    I guess I should take a look at how the vehiclebody and wheels are implemented and see if I can do something similar for a motorcycle but with more friction and including the self stabilising effects.

    I'm still curious why the joints don't work though.

    I know this topic is old, but, if it is of any interest to someone, I'm using Generic 6DOF joints for vehicles.
    So far, it is working.
