TNK - Replacement fork tubes (manufacturer's ref: 100-0050604). Designed to replace the original tubes, these plungers provide a simple and direct repair for worn or damaged forks. Made from nickel-chrome, they feature a smooth and durable finish that facilitates the sliding of seals and limits deposits on the surface.

• Usage: replacement of original fork tubes on sports/racing machines.
• Material: nickel-chrome — neat finish, good surface durability.
• Practical advantage: allows restoration of the plungers' condition without requiring complete replacement of a fork assembly.
• Availability: wide range of models available from TNK for different motorcycles.

Particularly suitable for YAMAHA YZF-R1 RN12 (2005–2006) listed among compatible models; however, please check the diameter and length before installation. Ideal for mechanics and riders who want to restore their forks without going through the manufacturer's workshop. Note: the manufacturer has not provided detailed technical specifications (tolerances, heat treatments, precise dimensions) — ensure exact compatibility with your model before ordering.
