⚠️ Important notes:
• This mount is an optional accessory — the smartphone holder case (iCase, ProCase, or UniCase) is not included and must be purchased separately.
• Check the diameter of your motorcycle's steering stem before purchasing: it must be between 17 and 20.5 mm.
• Not compatible with Interphone CRAB, ARMOR, and MASTER line mounts, which use a different 17 mm ball attachment system.
• For motorcycles with a smaller steering stem diameter (13-15 mm), there is a specific model with a different code.
• Installation is done by inserting the mount into the steering stem hole and tightening the locking screw. It is recommended to check that it does not interfere with steering rotation once installed.

Who is it perfect for?
The SMSTEERING17 mount is the ideal choice for motorcyclists who ride sport, naked, or adventure bikes with an exposed steering stem and want to have their smartphone always visible for GPS navigation, music, or notifications. Perfect for those who already use Interphone iCase, ProCase, or UniCase cases and need a secure and practical mounting point, different from the classic handlebar attachment. Also ideal for those whose handlebars are already occupied by other accessories (handguards, aftermarket mirrors, etc.) and need to use the steering stem as an alternative mounting point.
