CALCULATE and OPTIMIZE​
​MOTORCYCLE SUSPENSION and GEOMETRY.

CHASSIS SPECIFICATIONS FOR ​MORE THAN 100 MODELS.

MotoSPEC has a SIMPLE INTERFACE and CLEAR OUTPUTS,
to assist motorcycle manufacturers, tuners and race teams, to make
QUICK and INFORMED DECISIONS.

A fully-functional trial license with chassis data is available on request.

​MotoSPEC runs on Windows 10 or 11, on your PC or Mac.
MotoSPEC builds a virtual motorcycle, starting with frame and swingarm dimensions.
Forks, shock, triple clamps and tires are also specified.

Chassis geometry values ​and suspension characteristics are calculated, including:
  • trail
  • swingarm angle
  • anti-squat
  • wheel rates
  • wheel forces
Three setups can be compared with the same chassis specification.   
​The PRO version further allows three different models to be compared.

All chassis dimensions and specifications are editable.
Aftermarket components like yokes and linkages can be easily measured and input by the user.

MotoSPEC can also be used to design new components. 
For example, rear suspension linkages can be designed to obtain the desired motion ratio characteristics while also observing their effect on the chassis geometry.
  • Calculate front and rear suspension geometry and forces, throughout the suspension travel
  • Compare spring rates and preloads
  • Analyze and design rear suspension linkages
  • Understand the effect of pivot adjustments, air springs, bump rubbers and top-out springs
  • Calculate the effect of fork height and rear ride height on front steering geometry
  • Apply yoke and frame head inserts for angle and offsets
  • Plot chassis math channels to compare chassis geometry to throttle and brake pressure inputs
  • Center of Gravity Calculator
