TheKMX-9 V3is the latest evolution of the most popular karting combination ofAlpinestars. Designed to offer a perfect balance between comfort, durability and safety, it benefits from advanced two-layer technical construction that meets the highest protection standards.
The Carbon valves top (Sold per pair) are designed for motorizations Iame the most demanding. By replacing standard valves by these high quality carbon models, you optimize the intake cycle of your engine. Their calibrated thickness between 0.24 mm and 0.25 mm Offers the perfect compromise between low-speed flexibility and rigidity needed for senior regimes.
The Ø 20 mm circlips (landmark 33 On exploded TM Racing views) is designed to secure the box output gear on the secondary shaft. Its function is simple: prevent the gear from moving laterally or to detach from the vibration and changes in brutal reports.
Optimize the performance and appearance of your racing or recreational kart with these aluminum rear hubs of the highest quality.
Designed to provide maximum rigidity and precision, these hubs ensure a perfect connection between your drive axle and rear wheels. Made from machined aluminum, they combine strength and lightness without compromising your chassis's performance.
Adopt the spirit of Porsche Motorsport with our classic cut t-shirt, inspired by iconic liveries from the Porsche racing legacy. Spend effortlessly from the track to the street with this design in vibrant color blocks, highlighting a brand Porsche bold.
KIT MOUSSE HEADQUARTERS AND DOS NEW-LINE, BLACK
This 90 ° elbow kit (or cable guide) is the essential part to optimize the passage of your accelerator cable or starter. Designed specifically for type carburetors Dell'ORTO (SHA and PHBG Series)It makes it possible to deviate properly the cable when the space under the tank or the frame is restricted (current on MBK 51 mopeds, Peugeot 103, scooters and mécabites).
Made of high-strength treated steel, this kit resists perfectly with vibrations and hydrocarbon projections. It eliminates mechanical friction in the sheath, guaranteeing a ultra-flexible gas handle and an instantaneous handle return for your safety.
The secondary pinion DD2 Rotax is an essential part for engines Rotax DD2. Here are some detailed information about this product:
Column Direction 38/50 Long.490 mm for karting chassis OTK
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).
The 95 mm in magnesium is an extreme room. This is not comfortable equipment, it is a precision tool for high-level drivers (KZ, OK, X30 senior categories).
The hub of 95 mm is one of the longest models available in the range CRG. In karting, the length of the hub is directly correlated to the "lever arm" applied to the axle:
Deported support: With 95 mm, you drop the load of the wheel outwardly. This helps to charge the rear train in support more, ideal for tracks where you miss moving out of turn.
Aluminum rigidity: Unlike magnesium, this aluminum version offers high structural stiffness and excellent durability, while being easier to maintain and less sensitive to oxidation. Finishing Gold (anodized) effectively protects the part against premature wear.
The 105 mm in magnesium is a high competition room. This is not a basic setting, it is a specific solution for specific needs:
Maximum lever arm: With 105 mm, you drop the load outward to load the outer rear tire. It is the absolute weapon when the kart is sorely lacking on the turn out of turn.
System "2 screws": In a length of 105 mm, a one-screw tightening would be insufficient and would create an imbalance. The system to 2 screws Allows you to distribute the tightening force over the entire length of the ring, ensuring a perfect maintenance on the axle without creating a single voltage point.
Magnesium (mg): It offers valuable weight gain on non-suspended masses and thermal dissipation that stabilizes the pressure of your tires during long finals.
