The EAZ Silman LPA4 Premium Matte Black Free Flow Bend Pipe is an aftermarket exhaust component designed for Royal Enfield UCE BS3 and BS4 motorcycles.
The LPA4 is identified in the Silman catalogue as a Short Bend Pipe H/D UCE Black Coated O.E., making it suitable for riders looking for a short, heavy-duty bend-pipe configuration with a black finish.
Its matte black/black-coated finish gives the motorcycle a sporty and customised appearance and works well with compatible aftermarket silencers. The EAZ listing identifies the LPA4 for Royal Enfield Classic 350, Classic 500, Classic Chrome, Electra and Electra 350 applications in BS3/BS4 configurations.
The bend pipe can be used for replacement purposes or as part of a customised/free-flow exhaust setup.
Important
This is an aftermarket EAZ Silman exhaust component, not a Royal Enfield Genuine OEM part. Exact fitment can vary according to the motorcycle’s model year, UCE exhaust configuration and silencer being used.
