The size of this wheel is 17x2.50 and is designed exclusively for the smaller cc Supermoto bike conversions. Haan billet aluminum hubs, stainless steel spokes with a 3 cross lacing pattern on Excel Takasago rim. Imported direct from the Netherlands to the USA for supermoto duty by Motostrano. Our hubs are manufactured with the latest CNC technology, and are fully produced in the Netherlands. The production process is fully automatic, hubs are loaded with a robot to the machines. These hubs are CNC machined from solid 6082 alloy. For example a rear hub is machined from a solid block alloy that weighs almost 12 kilos going into the machine. Every little piece is machined out to create one of the strongest and lightest hub in the market. Hubs are assembled with Koyo bearings and hard alloy spacers. Hubs are available in various colours.  Some features of Haan Wheels supermoto wheels:      Hubs are made of billet 6082 aluminium and all precision CNC machined.     Standard brake discs and sprockets can be used on all of our hubs.     Hubs run oversized KOYO bearings, no special dimensions but sizes available world wide.     Most rear hubs have 3 bearings instead of 2 like some OEM hubs     The inner spacer tube between the bearings is made of 7075 billet aluminium.     The outer hub spacers are made of 7075 billet aluminium and have undergone a special hardening coating.     Seals are double working seals.     All our supermoto wheels are build with 36 spokes and have a special spoke pattern to create maximum stability, strength and space for the brake caliper     We use extra thick and super strong stainless steel spokes.
