5.5-Inch Air Cleaner Cover – How to Check It Fits Your Bike

Luftrenarlock 5,5 tum i aluminium med lasergraverat Crown-motiv

A new air cleaner cover is one of the easiest ways to give your motorcycle a personal detail. The cover sits right on the side of the engine and is seen straight away – but it has to fit your air cleaner. Here's what to check before you order.

1. Measure the diameter

Our covers are 5.5 inches, or 139.7 mm, in diameter. Measure your current cover straight across the centre, edge to edge. A caliper gives the most accurate result, but a ruler works if you're careful.

2. Check the mounting

The covers are made for round air cleaners where the cover is held in place by a single centre screw. If your cover has several screws around the edge, or a different type of mounting, it won't fit without modification.

3. Compare with the fit image

Each product page has an image showing the type of air cleaner the cover is intended for. Compare the shape with yours. Not sure? Send us a photo at info@04tretton.se and we'll take a look.

What's included?

  • Cover in powder-coated aluminium with a laser-engraved design
  • Black screw

The air cleaner itself and the filter are not included – you only swap the cover.

Ready-made design or your own?

Choose one of our ready-made designs, such as Crown, Lightning, Sweden Dyna or Good Ideas Bad Habits. Want something completely your own? We make an air cleaner cover with your design – artwork adaptation and a proof are included, and we only produce once you've approved the design.

Ready-made designs are normally made within 3 working days. Shipping time is additional.
