Billet Impeller Blade Upgrade

The 2014/2020 Yamaha YZF 250 introduced a new lightweight plastic waterpump impeller shaft design that has proven to be problematic because of the waterpump shaft snapping in half!

Riders are reporting failure at an alarming rate at around the 5 hour point and there has been at least one failure on a stock bike as early as 1.5 hours of race use . This is especially concerning as you won't know that it has failed until it is too late and serious engine damage may have occurred from overheating . We developed this waterpump shaft kit out of a heat treated billet steel to prevent corrosion and improve resistance to wear .
This billet steel waterpump shaft kit solves the problem for good.
