Many of you will have noticed in the news section of this site that the MSA have announced changes to the rear axle regulations. They basically have tidied up the words and added the requirement “Exceptionally axles for use in 210 and 250 National classes with a diameter greater than 40mm must have a minimum wall thickness of 2.9mm”
Now for whatever reason (likely to be the use of softer tyres in all classes?) we are seeing more axle failures which rightly has caught the MSA’s attention given the potential for serious injury or even death (as sadly for Rich Vito in the USA) resulting from a wheel with part of a broken axle attached bouncing down the track and colliding with a kart and driver.
Before this change to the regulations I understood that these recent axle failures were across all classes using hollow 50mm axles, indeed I myself witnessed a failure of this type only last weekend, so why have the MSA only addressed 210 and 250 National classes? Is it because they directly control these kart regulations and that they are not CIK classes or CIK based?
The MSA may well be in talks with the CIK about axle regs but in the interim they do seem to have little regard for UK karters and there safety. For instance the current UK Rotax regs say ‘any chassis that complies with the MSA regs’ NOT the CIK regs.
So:
1. Why change the 210 & 250 regs and not the KZ1 & 2 regs?
2. Why not address all kart classes with a similar axle design?
Finally why leave the paragraph in the regs that says “Please also refer to class regulations for any variations.” Do they really not care if the class regs allow the use of thinner axles?
In conclusion it would appear that MSA really don’t care about the safety of UK Karting but do care about being politically correct, I am sure that I have totally misunderstood the reasons for the changes to the regs and the underlying intentions of the MSA perhaps somebody could explain that to me?
