The Chairman’s decision is final!




In respect to the WDKRC’s Health & Safety policy, it has for some time been a club requirement that the specification for the back bar (Roll Bar) height for all karts is for the bar to extend to a minimum height of 2inches (50mm) above the height of the drivers head whilst the driver is seated upright in the kart with head back and helmet on.

It has been noted at recent race meetings that some karts are still failing to meet this requirement.

In future no kart will be allowed to race at a WDKRC meeting unless this specification is met. This will be checked at the point of pre-race scrutineering.

If your kart fails to meet the specified requirement, you will be given the opportunity to correct it before racing. There are welding facilities available at all WDKRC race meetings where the back bar can be set to the specified requirement. Welding is offered at a charge. Failure to correct the issue will result in refusal for that kart to be allowed to race, so it is in your best interest to ensure that your kart’s back bar meets the specified requirement before attending a WDKRC event.

This measure is put in place by the club in your own interest and in respect to your own personal safety whilst competing in a WDKRC race meeting, and is a requirement of the WDKRC’s latest Health and Safety policy.

The Committee. WDKRC.
