      The DOMA 100060 expansion chamber is designed for KTM EXC 250, EXC 300, SX 250 from 1998 to 2003. The expansion chamber is what gives a two-stroke engine its character. Well designed, it improves cylinder filling; dented by stones or crashes, it costs power.

      • 1 mm raw steel, laser-cut parts, pressed and then welded on a jig.
      • Developed on the dyno and on the track.
      • Works with the stock silencer or a Doma silencer.

      Good to know

      Fitting tips

      1. Reuse the stock connecting O-rings if they're in good condition (not included), or fit a new exhaust gasket.
      2. Offer up the pipe without forcing it, fit all the mounts, then tighten.
      3. Warm up the engine and check for leaks at the joints.
      4. Check the colour of the spark plug after the first few rides.

      Why DOMA?

      Doma Racing has been handcrafting its two-stroke exhausts in its workshop in Calais, France, since 1992. The brand won the 125 world title in 2000 with Grant Langston and supplies original equipment for certain KTM models.
