The integral stringwind is not an optional accessory, it is a centerpiece of karting safety. Designed to fully cover the chain, pinion and crown, it avoids any grease projection on the track and, above all, protects the driver and other competitors in case of chain break. Its "integral" design is a prerequisite imposed by the CIK-FIA Technical Regulations for all categories KF and OK. Compatible with all chassis marks, it adapts to your motorization in minutes.
Regulatory Compliance (CIK-FIA): Essential to pass the technical control. Without him, your kart is refused initially, no matter what engine performances.
Total protection: Unlike partial protections, the full model encloses transmission. In case of chain case (which even happens to the best), the links are retained inside the housing.
Universal: It is designed to be mounted on any standard chassis (OTK, CRG, Birelart, Sodi, etc.) equipped with a KF or OK engine.
Cleanliness: By confining the chain grease, you avoid projections on your tires, your combination and the rest of your chassis.
"We tend to forget the string barrier because it is 'closed' and we no longer see the chain. The trick: As it is an integral crankcase, you can not see the state of your chain at first glance. My Pro Council: Make the habit, every end of the day of rolling, quickly disassemble the housing (often fixed by some clips or screws quarter turn) to inspect the condition of your crown's teeth and the tension of your channel. A chain that lies down and who 'tape' in the crankcase, it is a risk of transmission blocking. Clean it regularly, because gum dust glued to grease can end up creating an abrasive paste that accelerates the wear of your transmission. "

Q: Is it mandatory even for private trials?
A: Although the technical regulation is formal in competition, it is strongly recommended to keep it at any time. It is a physical protection against the chain case, which can seriously damage the motor block or your arm in case of projection.
Q: My engine is an ok, will it cover the whole channel?
A: Yes, the design is designed to adapt to standard transmission reports used in KF / OK. The length is planned to protect the entire chain train.
To maintain your transmission efficiently under your new chain worker, make sure you have the right maintenance material:
[Graisse de chaîne haute performance] (To limit projections)
[Nettoyant chaîne dégraissant] (For preventive inspection)
The model Flat Out 330 High Grip is distinguished by its slightly more compact diameter (330 mm instead of 340 mm) and its technical coating designed to provide maximum friction with racing gloves.
High Grip Technology: The specific coating (textured polyurethane or high density alcantara in serial) makes it possible to maintain a firm socket with less physical stress, thus reducing the cramps and the fatigue on the long sleeves.
Diameter 330 mm: This shorter format offers a brighter and more direct direction, preferred by KZ drivers (gearbox) or those seeking instant reactivity.
Ergonomic structure: Profiled branches for quick access to pallets (clutch or steering wheel brake) and a clear reading of the instrumentation.
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.
