The Starter return (ref. 251552), often called "Bendix", is a complex mechanical assembly consisting of a mobile pinion on a helical axis. Its role is to project forward under the effect of centrifugal force to cross the start-wreath. Once the engine is launched, the return spring the retracts the retracts to prevent contact with the motor. It is a high precision piece that undergoes important shocks at each start-up.

The CRG Kt2 is the versatile chassis par excellence of the Italian manufacturer. Unlike the Rébec Road (more rigid), the KT2 uses a frame compound full of tubes of 30 mm in diameter. This architecture offers controlled flexibility, ideal for freeing the engine in categories without gearbox like the OK, Iame X30 or the Rotax Max.
Its geometry allows fast adaptation to all track conditions (high grip or green track "). Featuring the last components of the range CRG RacingHe combines exceptional motor skills at a surgical front train accuracy.
The CRG KT2 2026 Version Kz redefines the standards of the Queen category. While the Road Rebel (32mm) remains the choice for the tracks with very high grip, the KT2 in 30mm Has become the favorite weapon of Kz pilots looking for more agility and ease in the support changes.
For 2026, CRG Reworked the composition of chrome-molybdenum steel to provide a better response from the front train during degressive braking. This KZ version stands out for its localized structural reinforcements and its integral front / rear braking system, essential to stop the power of 50 horsepower engines
The hub of 35 mm long is considered a "short hub". In karting, The choice of hub length is a fundamental adjustment tool:
Short hub (35 mm): It offers less contact surface with the axle than models of 75 or 90 mm. This usually allows to have a "freer" behavior of the rear train, Helping the chassis to be free from curve, Ideal on tracks with a lot of grip (adhesion).
The hub of 40 mm long is often considered the "standard" or "versatile" value on adult karts equipped with a 30 mm (x30, axle, Rotax, Kz, ok). Unlike very long (75-90mm) hubs that considerably rigidify the rear, or the very short (35mm) that fully freed the chassis, the 40 mm Offers neutral and healthy behavior, ideal for starting a setting session before refining.
The hub of 85 mm is a "long" adjustment room. In karting, the choice of the hub length is directly related to the leverage exercised on the axle:
Stability and Grip: With 85 mm, you increase the rigidity of the rear train and removing the load outward. This is the ideal tool for more moving output output or to expand your back path without stacking spacers (which weakens the assembly).
R2.0 version: This name indicates an evolution of design at CRG (best machining, optimized weight and anodized finish "Gold" for higher resistance to corrosion).
