Spark Arrestor Adapter

Will need this adapter along with a Spark arrestor Click Here!

We developed an internal adaptor for the trials bikes that don't have a silencer end you can attach our spark arrestor to, the internal adapter uses 3 set screws to secure. Then our standard spark arrestor (31.5mm) attaches to the adapter with 3 set screws.

Internal Adapter is for trials bikes that do not have a silencer end that extends out for a spark arrestor to attach to

-On the internal adapters see the sizes in the drop down option and measure your Inside Diameter on your bike to determine which is the best fit.
