On this page, we will talk about the geometry of the bike.

The config file is found on NAMEOFTHEBIKE.geom


Unofficial Bike Tool

A first tool is available here. It displays the 990 model and its geometry points : https://mega.co.nz/#!4MQx2Dpb!WEskhgJgRAg5vbCNvLoeWR4E9FMYpynvXncC6PwTNxU

The same, but with the scooter : https://mega.co.nz/#!hEwyGYBZ!cS6x1xs1FsAghIzuyMfXvh3kSt0Ye7S0SXk9Wu1wH88

You will need geogebra to open it : http://geogebra.org

The chassis and swingarm are working (dynamicly set).

The front fork and lower fork are still not correctly linked to the chassis (relation is missing).

  • Be careful ! The coordinates system used is (x,y) in geogebra = (z,y) in GPB !!!
  • You only have to change the original parameter name (without '). All other points are processed dynamically !!
  • The background image has to be scaled first to be used !!
  • The collision box will be available in a future version, as well as the different measures

General info

  • Units are in meters for the coordinate
  • There is more than 1 reference (some parts have a reference to other part)

The reference system

  • X> left (-) / right (+) of the bike
  • Y> height of the rider
  • Z> forward (+) / backward (-)
Scoot uncompressed 2





There is 5 groups (ie reference system) in the bike model :

  • Front wheel
  • Steering head
  • Chassis
  • Swingarm
  • Rear wheel

The file itself

Bike info

type = bike
id = Varese_V594

Your id should match the id in config file


Reference : Chassis

chassis_mass = 0, 0.450389, 0.0104752

Position of the center of gravity of the chassis


chassis_steer = 0, 0.786057, 0.380405

Position of the center of gravity of the steering elements (triple clamp, ...)


The rider

rider_mass = 0, 0.856091, -0.3
rider = 0, 0.85, -0.42

Rider mass and center of gravity


Front sprocket

front_sprocket = 0, 0.373401, -0.135777


Footpegs

footpeg_left = -0.22, 0.4, -0.2
footpeg_right = 0.22, 0.4, -0.2

Position of the footpegs


Rear suspension pivot

chassis_rsusp_min = 0, 0.423847, -0.208398
chassis_rsusp_max = 0, 0.423847, -0.208398

Extreme Position of the swingarm pivot point.

swingarmpivot_steps = 2

Number of adjustment possible between these 2 points 


Misc

fuel = 0, 0.704142, -0.0947883

Center of gravity of the fuel mass

pressure_center = 0, 0.553665, 0.147739

?? 

t-cam = 0, 1, 0.02

Point of View (cockpit view)


Fork

Rake angle

rakeangle_min = 20

rakeangle_max = 24

rakeangle_steps = 4

These parameters defined the rake angle settings (min/max and how much settings available)

What is the point where it is attached???


Handlebars

grip_leftpos = -0.25, 0.00804171, 0.0415888

grip_leftdir = 1, 0, 0

grip_rightpos = 0.25, 0.00804171, 0.0415888

grip_rightdir = 1, 0, 0

Handlebars position and direction


Fork 

front_length = 0.12

Travel distance of the fork


Reference : upper fork

steer_mass = 0, -0.18679, 0.025183

steer_joint = -0, -0.104652, 0.0151901

front_upper = 0, -0.319211, 0.020801

??


Reference : lower fork

front_lower = -0, -0.392818, 0.0226877

??

fsusp_mass = 0, -0.529466, 0.0218526

Reference : swingarm

Rear swingarm length

rwheel_min = 0, -0.0739481, -0.535805
rwheel_max = 0, -0.0804631, -0.577924

Maximum and minimum position from the rear wheel in the swingarm referential


swingarm_steps = 2

Number of adjustment possible between these 2 points 


rsusp_mass = 0, 0.0314265, -0.278455

Position of the center of gravity of the swingarm


rsusp_joint = -0, 0.0739473, 0.025401

??  rear_upper = 2

rear_lower = -9

Upper and lower angle of the swingarm (when suspension is fully compressed/uncompressed


rear_length = 0.06

??? Travel distance of the rear shock  or length offset of the swingarm  


Collision objects

These elements defines what will be the contact points from the chassis, front suspension and rear suspension with the world.

The chassis, fsusp and rsusp elements have each their own referential.
