CRF250R 2006-08 Spark Arrestor End Cap Set
[PMB-01-1102] $249.95
We designed Endos as an economical way to convert your stock muffler into a U.S.F.S. approved spark arrested muffler. When the spark arrestor screens are not required—such as at the MX track—simply remove three machine screws on each end cap and take out the screens. It’s as simple as that. Each end cap is machined out of solid 6061 aluminum and installs quickly and easily.
Key features:
U.S.F.S. approved and engraved accordingly
Includes removable, replaceable, screen type spark arrestors
Color anodized removable end cap nozzles
Hard clear anodized for durability and protection from the elements
All hardware included for installation
Each Endos spark arrestor includes an end cap assembly with color anodized removable nozzle, a spark arrestor screen, and all required mounting hardware. See Installation Instructions for model specific installation requirements.
Fits 2006-08 Honda CRF250R twin pipe models only. (Sold as a set with two end caps.)
