Design and Engineering
Do you want to modify or prepare your motorcycle? Would you like to know how to improve it? Do you want to simulate a modification before making it?
We can study your idea or motorcycle and outline the possible modifications, look for options and simulate them to obtain the one that best suits your need and then design it and find a way to bring it to reality.
From things as simple as the position of the footrests, geometry and suspension to engine components and expansion chambers, we can do it!
EXAMPLE: ANGLE OF THE SHOCK ABSORBERS
In this case, the objective was to prepare a Montesa Cota 172 for classic trials competitions. They wanted to change the shock absorbers for adjustable ones that are available in 340, 3500, 360, 390 and 400 mm.
As it was not desired to modify the height of the motorcycle, nor the upper mounting point of the shock absorber, then, the different positions are the ones represented in the image. As you can see, the mounting point in the swingarm varies, and also does the hardness of the suspension, the travel and the loads that the swingarm supports. The angle of the dampers also varies, altering the initial progressivity of the system.
What then is the most suitable shock absorber for us? You have to find a balance between progressivity and travel, as well as calculate the constant of the new springs and reinforce the swingarm to support the new loads without adding more extra weight than necessary. At Orengo Engineering we have the tools to simulate the different cases, as well as the knowledge to choose the best compromise, and make your machine a winner!
EXAMPLE:
FLOATING BRAKE
The floating brake stays are a good solution to separate the rear braking from the suspension and eliminate the loss of grip when braking on uneven terrain.
But how should we make the brake stay? The angle and length of the stay are crucial for the correct operation of the system, if done wrong, we can even make the initial problem worse.
At Orengo Engineering we have the ability to simulate these and many other problems that may arise and obtain the optimal solution for each case.
In the image you can see a case applied to a Bultaco Pursang MK8, where the effect of a brake stay with the same angle but different length. can be seen.
