Valve White Diamond® – KIBBLEWHITE (ref. 60-60516H)
Machined exhaust valve for motocross competition, the White Diamond® from Kibblewhite combines precision manufacturing and advanced surface treatment. CNC machined from forged monobloc stainless steel EV8 or Inconel-751, it meets the demands of high-stress engines. The coating is electroplated with a 360° anode to achieve a uniform hard chrome film over the entire head and stem.
Designed to fit into motocross cylinder heads, this valve features precise dimensions and a defined tulip profile, useful for seat and guide adjustment in heavy-duty use.
Frequent compatibility: SUZUKI RM‑Z 250 (models RJ42A/C 2017, RJ41A/C 2009, RJ41A 2007). For secure installation, check the dimensions with your cylinder head and adhere to manufacturer specifications when replacing.
