MX Bikes supports 4 types of front suspension geometry.
1) "Telescopic". Used on almost all racing bikes.
2) "Push Arm". The front wheel is attached to an arm, with the pivot behind.
Example: speedway bike.
3) "Trail Arm". Same as push arm, but the pivot is in front of the wheel.
4) "Rigid". There is no suspension and the front wheel is connected directly to the steer.
Probably only used on minibikes.
