Take control of your motor skills and affine the behavior of your kart thanks to theOriginal back tree CRG 50 mm diameter in length 1020 mm. With the iconic black protective finish of the Italian brand, this axis is the key element to calibrate the flexibility of your rear train depending on the track condition and the type of tires.

The length of 1020 mm offers an excellent geometric compromise: it allows to tighten the back path to release the chassis in fast sequences or meet the technical requirements of certain categories (OK, KZ, Rotax, X30). Available in the entire range of catalog hardships CRG, this tree goes from the very flexible version S20 (To avoid kart to cling on a too wrapped track) until the ultra-rigid version T5 or reinforced versions R (2.5 mm) To force the tire to find a grip on cold track, slippery or soggy.

Optimize the behavior of your rear train and refine your curve motricity thanks to theOriginal back tree CRG 50 mm diameter. Recognizable with its high-end protective black finish, this axis is the essential centerpiece to set the chassis of high efficiency competition categories such as the Kf (high performance monovite) and the Kz (Queen's gearbox category).

On a competitive kart, the ability of the axis to bend under the side stress directly determines the amount of grip. That's why we propose you, via our drop down menu, a multitude of declensons combining several official lengths and hardships. To meet the extreme physical constraints of the KZ category (big pairs with acceleration, full braking), favor the marked versions of a R (R = reinforced). With their wall thickness carried to 2.5 mm (as on models S25, T1, T4 or M25), these reinforced trees stabilize the rear yard and avoid rebounds (chatteringWhen discounts of violent gases, while 2 mm thick versions (such as the original M20 or T2) offer perfect gradual flexibility for the delicate tracks.
