Good ideas to build
LA MOTO2 PROJECT suspension 1 from Beltrance on Vimeo.
As you probably had noticed, if you used to come to this café, it has been closed for a while. We’ve been really busy with the LAMOTO2 project and with other projects that unfortunately are paused (hope that not stopped)
Here in Spain you can read monthly about our progress but not abroad. So I wanted to show at least a part of what we’re doing.
First of all this little video.
Take a seat and enjoy our delicious coffee!
I have prepared a mini video to show the idea of the system that carries our moto2. In yellow you can see the vertical arm. The thick lines is the part and then up thinner line the real steering axis. The pink line is the top of the steering column of the system, which looks like a fork. When the system compresses the top is “folded”. Therefore there is a ball joint in the joint, to absorb this inclination. Initially the diference is 2 degrees, not zero on purpose. To ensure that the “fold ” goes forward and not backward. At the end it arrives to 7 degrees of tilt for a compression of 120mm. These 7 degrees is absorbed by the green piece that goes in the front of the bike (this is why is a plate) plate that flexes the 7 degrees but kept intact the steer stiffness, work in shear effort. Another thing you see is that the center of the wheel follows almost the same path as a 12 degrees fork. Thus the pilot feel much like a conventional bike and trust the bike from the start.
With this trick, the mechanism, that is an evolution from the patent of the D1200R Demonstener solve the problem of getting a direct steering to the Hub Center Steering System. In this case applied to a system derived from the Difazio. This was one of the desired conditions in the project (no Bump-Steering). If you look you will see that history is an evolution of our prehistoric V2R StreetDumper
Hi everybody!
I’ve done a basic geometry of Lamoto2 Hub Centre Steering bike in 3D
It will be updated with your help.
Front wheel travel is 120mm
Anti-dive equivalent to 12º fork
There can be mistakes, so please report everything you see.
60º laying is no tested, neither 15º steering
Wher can we put the front suspension??
There’s a lot to do!

Hi everybody!
This is a present for all the builders and designers that want to build an Honda based motorcycle, and specially for those who want to build a MOTO2.
Probably you know that we’re building an alternative suspension MOTO2 for the CEV.
We have scanned and rebuilt the complete CBR 600RR engine from a digitalized. I hope you’ll like it. The critical points are perfect but obviously the rest it’s closer and in the worst places can be over +-5mm.
If you were a reader of this blog you’ve probably seen I’ve got less time to write. But please send all your comments o doubts and I’ll try to answer you ASAP :-)
See you here at the NewConceptsCafé!
Obviously Edward it’s a master of motorcycles and I hope he will find a bit of time to spend in the Moto2.
I think it’s a very interesting bike. What do you think about it?
He also sent me a very interesting paper and some pictures of a bike I’ll publish in other post.

SYSTEM 2 CALLED D-D-P (DEMONSTENER-DIFAZIO-PARKER)
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!
