The high-quality wheels with CNC machined hubs and high-strength 7050 aluminium GIANT rims are assembled in Mattighofen. The new spokes are covered with noble black coating which improves the corrosion resistance. Especially developed for KTM, are the new MAXXIS FIM tyres (80/100-21" MAXX CROSS 7311, 120/90-18" & 140/80-18" MAXX ENDURO 7314) which provide excellent traction, very precise cornering and top durability.
