KYB Mid-Valve Bypass Kit (24mm)

KYB 48mm Fork – Mid-Valve Bypass Kit (24mm)

The Lainer Suspension 24mm Mid-Valve Bypass Kit is designed for riders looking to soften the initial damping feel of their KYB 48mm forks. This kit replaces the stock leaf spring mid-valve with a traditional spring-style design, commonly referred to as a cup/spring mid valve system.

This configuration promotes earlier shim movement and allows for more initial fluid bleed, creating a noticeably plusher, more compliant ride—ideal for technical off-road, trail, and enduro applications or those who just want a more plusher fork.

*Kit comes configured with mid-compression shims.

Key Benefits:

• Softer Initial Damping Response
  The coil spring setup allows earlier shim deflection, reducing front-end harshness in small chop and technical terrain.

• Optional Float Tuning
  Can be configured with or without float depending on your desired feel. Float allows for even freer initial movement, ideal for low-speed trail obstacles and comfort tuning.

• Increased Comfort and Compliance
  Especially useful for riders who find the OEM KYB leaf spring system too firm or harsh in slower-speed riding conditions.

• More Forgiving Setup
  Helps reduce rider fatigue by allowing the fork to move freely through the top of the stroke, improving traction and comfort over long rides.

Designed for Off-Road, Trail & Technical Terrain

While the stock leaf spring system offers greater low-speed hold-up for motocross and race environments, this bypass kit prioritizes comfort and traction for a more plush feel, an ideal choice for trail riders, offroad and enduro applications.

Application: Compatible will all KYB forks that come with a 24mm mid-valve
