Pushback Bumper System Clarification for Remaining 2017 Prokart Challenge Events in X30 Junior and Senior
Monday, 12 June 2017 15:56

X30 Senior and X30 Junior - In all official track sessions (practice, qualifying, heats and final) the Pushback system must be installed. Failure to have it installed in official practice sessions may result in the loss of practice sessions.

In qualifying, heat(s), and the final, each driver must enter the pre-grid or grid area with the front fairing detached from their kart. The mechanic or the driver himself/herself must mount the front fairing without the use of tools under the supervision of the grid steward(s). The fairing will be inspected for modification or excessive wear.

The use of a homologated front fairing and of the homologated front fairing mounting kit of the bodywork homologation period 2015 – 2020 is mandatory. The use of the KG mounting clamps is not required (as an example, OTK clamps are acceptable). But KG mounting clamps are highly recommended for their additional strength.

The front fairing (using the front fairing mounting kit) must be in the correct position at all times during a competition session. (see CIK Technical Drawings No. 2d and 2c)

  • The black flag with an orange disc will not be shown to a driver if his front fairing is no longer in the correct position.
  • If the front fairing on one or more karts is no longer in the correct position after the race, a time penalty of 10 seconds will be imposed automatically to the driver(s) concerned. This time penalty is not susceptible to appeal.
  • Should a driver or another party be found to have intentionally replaced or repositioned a dislodged front fairing to avoid detection by a grid steward, that competitor shall be immediately excluded from the day’s competition events.
