These clip ons use a 25mm OD riser for extra rigidity (but still have the 22.2mm handle bar tube)as they are 45mm higher and 15mm back also 10mm wider than the factory items, they do clear the fairing and tank and the standard brake line , clutch and switch block wiring can be retained. Note: the mid rise option at 30mm higher is our most popular design this extra high was design specifically for a customer with a partcular injury who requested them as high is possible.
