Description

Compatible Models: KTM Duke 250 & KTM Duke 390, BS4 emission version. MySpareMarket+1
Part Number: JY591275. MySpareMarket+1
Description:
A pre-silencer/mid-pipe “bend pipe” section of the exhaust system made for the BS4 version of the Duke 250/390. This part is engineered to take the exhaust gases from the engine header or catalytic converter section, through a correctly routed bend, aligning with the rest of the silencer assembly.

Key Features:

• Exact fit for Duke 250/390 BS4 models (ensures proper alignment of exhaust system). MySpareMarket+1

• Durable construction designed for exhaust heat, vibration and emission-compliance re-routing.

• Maintains stock exhaust path and mounting geometry, so the rest of the exhaust system (silencer, mounting brackets) can remain unchanged.
  Fitment Notes:

• Must be used on BS4 variant of Duke 250/390 (verify model year and emission standard). MySpareMarket+1

• When replacing this section, ensure gaskets, clamps, and mounting hardware are in good condition (often the weakest points when leaking starts).

• After installation check for exhaust leaks at joint, correct alignment, heat shield clearance.
  Benefits:

• Enables restored or replaced section of the exhaust when the original bend pipe is damaged (corrosion, denting, impact) without replacing the full exhaust system.

• Preserves the correct routing which helps maintain engine performance and exhaust dynamics.
  Precautions:

• Boxes labelled “aftermarket” may differ in material or wall-thickness, so verify that the part is genuine or high quality.

• The finish and weld quality matter because this part sits in a high-temperature area.

• Be sure that the part matches your exact bike generation and variation because even within Duke 250/390 there may be minor differences (header outlets, bends, mounts) depending on year & region.
