The needle cage IKO KTV 151920 B2 is the critical link element between the piston axis and the connecting rod. In a KZ motor (TM Racing, Iame, Modena), this piece undergoes extreme stresses (more than 15,000 rpm and massive combustion pressures).

Selection B2 guarantees an ultra-tight manufacturing tolerance between 0 and -2 microns, ensuring a perfect operating game to reduce friction and prevent motor case.

🏎️ Why choose the IKO KTV B2 cage?

1. Tolerance "zero defect": The selection of 0 to -2 microns allows a precise pairing with your piston axis and your rod, avoiding the excessive beat or overheating.

2. IKO Quality (Japan): Recognized worldwide for the hardness of its steel and the precision of its needle bearings.

3. Advanced heat treatment: Designed to maintain its shape and resistance even under the highest combustion temperatures.

4. Special KZ: Dimensions 15/19/20 mm Specifically adapted to the standard rods of 125cc gear motors.

💡 Michel's trick

"The piston cage is not the place where you have to save money! My advice: When you redo your piston (every 8 to 10 hours in kz), systematically changes the cage. A loose cage is a complete engine with trash (cylinder, rod, carters). Little trick with mounting: generously lubricates the cage with 2T mixing oil before inserting it. And above all, check that your rod is not marked (blue or scratched) at the level of the head eye, if not even a new IKO cage will not hold long! "

🎓 Mounting Guide

• Lubrication: Never mount the "dry" cage. Use a quality oil (type Lexoil or XPS).

• MANAGEMENT SENS: Well center the cage in the rod eye before inserting the piston axis.

• Control: If you change the brand of connecting rod or piston, always check that the 20 mm width leaves a lateral game sufficient for the passage of gases and lubrication.
