KIBBLEWHITE – Valve Guide (manufacturer part no: 60-60320)

Valve guide machined in the USA from nickel-aluminium bronze C630 (C63000). Its composition — approximately 80% copper and 5% nickel — provides excellent thermal conductivity and good wear resistance, essential criteria for cylinder heads subjected to high temperatures in motocross use.

• Applications: intake and exhaust
• Material: C630 Bronze (nickel-aluminium)
• Outer diameter: 0.4170 in (≈ 10.59 mm)
• Inner diameter: 0.1955 in (≈ 4.97 mm)

The guide profiles are designed to limit the impact on airflow while maintaining critical thickness in high-temperature areas — an important compromise for the durability of valve seats on off-road motorcycles. This part is intended for engine preparations and repairs, primarily compatible with motocross models.

Compatibility examples (top 3): SUZUKI RM‑Z 450 (RL42A) 2007, SUZUKI RM‑Z 450 (RL41A) 2006, SUZUKI RM‑Z 450 (RL41A) 2005.

Ideal for demanding mechanics and riders looking for a quality OEM-style wear part for the refurbishment of motocross cylinder heads. Always check dimensions and compatibility before installation.
