La Moto2: Hub-Centre-Steering front suspension System 2 (Demonstener-Difazio-Parker)

Originally posted on by the autor.


It’s based on the mentioned systems. It’s main advantage it´s the arm placed over the wheel. It’s relationed in some way with the Ecosse Spirit system. It´s like system D-D but I think it can be lighter.
The biggest inconvenient it’s probably the cooling. There’s less free space for the radiator in the front part of the bike. 
Both systems, as you can see are rod-end free for a better precision, even if they are more complicated and heavier.

What do you think about these systems?

Any idea for a better performance?

 Do you a have a better system and you want to see it on the racetrack? 

I wait for your comments!

    In my opinion, its important that a hub centre steering system is as simple as possible.

    Therefore I would like to recommend to take a look at the design of Mr. Tryphonos:

    Advantages: relatively small number of parts – minimum number of bearings

    best explained in the patent:

      Hi Franz!

      We´re really working on a very similar system. 2 arms on both sides. And a mix of Difazio and Demonstener. The key must be the direst steering to make the pilot absolutely feel the tarmac. So it will be a different solution but similar concept.
      Other thing we´re working on it´s to make the bike sensations more similar to a common MOTO2. We want the pilot to immediately trust the bike.

    Hello Carlos, interesting project. Have you seen this system (from JBB)
    What I was wondering if one needs the upper frame structure and can built the airbox in carbon fibre and integrate the headstock and mounting points of the upper a-arm into it?
    Best regards,

      Very interesting and simple the JBB it´s similar to the Metiss, isn´t it?

      Itás not possible to change tha airbox but in fact we will incease its volume but growing the font part. Maybe Carbon fiber and yes, including the headstock wolud be an interesting option.

    Thank you Carlos. I was having a hard time understanding.
    The single sided front suspension no longer an option? What I see surfacing in all the designs are complexities and many small delicate components. Keep it simple. Remember the bike will crash.
    Hope you can review I found his design to be very clean. It would be fantastic to make it single sided.

    I think the Metiss and JBB are the same systems (same designer). After reading the rules of Moto2 it seems the airbox much be standard, which is a shame…good luck with the project!
