Koyo Bearing - 6204 2RS C3 Bearing (Rear Wheel Bearing)

A high-spec, double-sealed ball bearing designed for smooth, durable rear wheel performance. The 6204-2RS C3 features rubber seals (2RS) to protect against dirt and moisture, and a C3 clearance rating to handle heat expansion and reduce friction—ideal for long-distance riding and everyday use.

Though often replaced by dealers during servicing, this bearing can also be installed at home with the right tools and some mechanical experience.

Why it works for Triumph Modern Classics:

✔ Double-sealed to keep out road grit and water
✔ C3 clearance ideal for higher heat and sustained speeds
✔ Suitable for home installation with the right tools and experience
✔ Cost-effective replacement for worn OEM bearings
✔ Trusted spec for rear wheel durability and performance

🔧 Note: Two bearings are required per rear wheel (left and right). Sold individually.
