Check out rccomponents.com... they make custom wheels for 900 Classics and many others.
I can tell you the 1700 Nomad front won't work, same size tire but the axle is bigger. 32mm for the Nomad, 26mm for the Classic LTI am looking to replace my front and rear rims.....have a '07 900 Classic. It seems to me that as long as I get the same size rim 130/90-16 (front) and 180/70-15 (rear) I should be able to put them on my bike. Has anyone put rims from a 1500 or 1700 on their bike?
How much for the rear wheel?I have a 900 custom rear wheel forsale if someone is interested.
