Fitting general rule of thumb: 8.3mm fits most Italian (Ducati, MV Agusta, Aprilia) and Triumph Motorcycles.

Additional fitting information: Valve stems needs a flat region of 15.3mm (0.6in) around the valve stem.
  • To check the clearance, use a socket that is about 16mm in outer diameter.
  • Place socket around the current valve stem with the valve stem sticking though the center of the socket.
  • If you have a flat region that fits a socket of about 16mm, then you should have enough clearance.
After Market Rim Fitting:
  • Rule of Thumb: 8.3mm Fits Aftermarket Rims (Cerchi Antera, Marvic, Marchesini, OZ Racing, Brembo, Etc.)
    • Check the rim opening, some used rims have been modified to accept the larger 11.3mm valve stem.
    • Some manufactures make special "Street" rims with 11.3mm.
  • Check your aftermarket rim valve stem hole before ordering!!!
