Choosing the Right Axle
Softer axles increase rear grip and help in low-grip or wet conditions.
Harder axles free up the kart and improve performance in high-grip conditions.
Medium grades provide balanced handling for general use.

Something of a treat in the NextKarting workshop this week – a 2000 Tony Kart Mitox. This kart has undergone a full restoration, including powder coating, with all parts either re-coated or replaced where required. The kart was supplied direct from Tony Kart in Italy and later owned by a former karting champion, who now works at the highest level in Formula 1. The only minor issue to note is that during the powder coating process the company shot-blasted the chassis number plate, meaning the chassis number is no longer visible. Overall, the kart looks absolutely stunning, and examples like this very rarely come up.
