The PKT axle is often over 5.0lb lighter than solid steel axles on the market! That's un-sprung rotating weight just waiting to be taken out of the powertrain!
Each axle is 970mm in width allows for maximum track width, with wall thicknesses of 2.1 or 3.0mm available.
- A thicker wall will make an axle more stiff, which typically creates more rear grip / traction in a kid kart application. Conversely, a thinner wall will be more flexible, generating less rear grip / traction in corners.
- **Point Karting recommends the 3.0mm wall thickness for new Kid Kart racers, as this creates slightly more rear grip. While it is true that the increase in wall thickness creates slightly more rotating weight, and therefore slightly less speed on straights, the difference is marginal, and the benefit of having a stronger axle more averse to bending (and needing replacement) outweighs such a small change.**
