DescriptionThe whole story▼

Accossato's CVN01, in orange, is the exhaust valve cover listed for the KTM 300EXC's 2007-to-2016 build, closing over the exhaust valve control mechanism at the back of the cylinder. This two-stroke's valve system is shared with several other bikes in the Husqvarna and KTM ranges, so the same cover reappears more than once across the catalogue.

Key Features

  • Exhaust valve cover for the KTM 300EXC, 2007 to 2016
  • Accossato code CVN01, closes over the exhaust valve control mechanism
  • Available in orange
  • Accossato also lists a second version, CVS01, in blue or black, for this bike
  • Same part also listed for the Husqvarna TC 250, TE 250 and TE 300
  • No German ABE on file; built for off-road and competition riding

Construction and Material Quality

Accossato's CVN01 is the orange exhaust valve cover for the 300EXC, closing over the control mechanism in place of the standard part; the identical code also covers the Husqvarna TC 250, TE 250 and TE 300, named again below. Choosing this version over the CVS01 is purely down to wanting orange rather than blue or black. A cracked edge or discolouration well past the usual tint are the signs worth a second look.

A Cover Owners Learn to Check by Feel

Because it sits tucked in near the exhaust side of the cylinder, this cover is easy to miss on a quick visual check but simple enough to run a thumb over during a wash or a pre-ride once-over. A build-up of baked-on residue is the usual thing found that way, and wiping it away before it hardens keeps any hairline cracks visible underneath. Owners who service their own bike regularly tend to fold this into the same pass as a chain clean.

Fitment and Compatibility

The 300EXC's full 2007-to-2016 production sits on the CVN01's own application list, as Accossato sets it out. This cover also fits the Husqvarna TC 250, TE 250 and TE 300, all built around a related exhaust valve system, so an owner of more than one of these bikes can standardise on the finish they prefer. Matching the exact build year against that list before ordering still applies here.

Road Approval

No German ABE is on file for the CVN01, so Accossato lists it for off-road and competition use rather than for use on public roads.
