Brake system The brake systems were updated both in the mixture of brake pads and in the treatment, especially the cast iron brake disc D.180 to improve the breaking and the wear.Spindles: The spindle remains the classic “2 pieces” with the introduction of a new thicker spindle stem made out of a more noble material with better characteristics. The main goal of the "H" stems will be to give more insertion increasing the grip on the front of the chassis.Rear Axle: A variety of 8 axles are available for this chassis. We introduced the new “R” axle that stands out for it's very good side seal, good stability under braking and optimal traction while leaving the kart very “free”. From now on, the rear axles will be specifically produced for KF categories with only 4 keyways (for outer crown). The sizes of the KF axles is 50x2x1020mm. (only one comes with the kart)Graphic kit: All the racing karts will have new Ricciardo graphics, revised and improved for a modern and trendy look.Magnesium: New fully machined 50x115 mm double screws magnesium hubs were introduced bringing more versatility to the standard factory 50x90 mm. There is always the possibiliy to order the karts in “FACTORY” version with both front and rear (50x90) magnesium hubs.
