Do you need a lower profile spark plug for a KTM 65SX?
The BR8ECM is just a low profile version of the BR8ES, if you dont need the low profile, dont use it, its spendy. As far as I know, the KTM 65SX calls for this plus, there is a frame member in the way and it need to have the lower profile plug. But I dont think any other KTM needs the lower profile unit.
