Constructed of stainless steel and 6061 T-6 billet aluminum, unlike the stock pumps, which are made from weaker cast aluminum, plastic and brass. These performance pumps are a direct replacement for the inefficient OEM aluminum 6-vane stator section. 148 mm stator is an upgrade intended for freestyle riders; requires use of YRS series Concorde impeller. Includes 12-vane stainless pump, pump cone and dual cowling with brass fittings. Use OEM Yamaha bearings and seals.
