KPMI 4/Pk Universal Valve Stem Seal Honda CRF450R | CRF450X | Kawasaki KX450F | KLX450R | Suzuki RM-Z450 2002-2017 - 71016-4
KPMI solid Viton valve stem seals are designed to have optimum fitment, allow for maximum lift, and to give maximum life. KPMI Red valve stem seals are resistant to high temperatures, petroleum products and the corrosive gasses that are the by-products of combustion. These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combustion chamber causing detonation, carbon build up and a loss of power. The Red Ones are truly the racer's choice.

Fitments:
  • Honda CRF450R 2002-2008
  • Honda CRF450X 2005-2017
  • Kawasaki KX450F 2006-2016
  • Kawasaki KLX450R 2008-2012
  • Suzuki RM-Z450 2007-2016

KPMI Quality

KPMI's objective is to supply consumers with products that function correctly the first time and deliver the best value for money in terms of reliability and performance. None of their products reaches final approval without first enduring a development flow procedure. Three signatures from engineering and one from production are required for final evaluations. This means that each product undergoes three independent assessments throughout its development process before a final product is launched.
