{"product_id":"kt-307-0413340","title":"WPC Clutch Center Spring for Axis Treet","description":"[KITACO 307-0413340 WPC Clutch Center Spring for AXIS Treet]\nFeatures a special surface treatment and WPC specification that makes it highly resistant to heat fade and offers excellent durability.\nThe heat resistance has been significantly improved through nitriding, and residual stress in the surface layer has been removed with WPC treatment, greatly enhancing fatigue strength.\nBy strengthening the spring, the WPC clutch center spring promotes pulley shifting within the torque band, and quickly and forcibly returns the pulley to a low ratio from a high ratio state during sudden acceleration from deceleration or on inclines, providing sharp shifting characteristics.\nThe WPC clutch center spring, like weight rollers, is a tuning part, so the optimal spring strength will vary depending on the rider's weight, the machine's usage, and even individual preferences for riding characteristics.\nInstalling only the center spring can hinder shifting, potentially leading to a decrease in top speed.\nFree length: 115mm\nOuter diameter: 61mm\nLoad at operating condition: 377N\nCompatible model: AXIS Treet\n*The image is for illustration purposes only.
