DHM Titanium Retainer kit for 2-valve heads (2014-2020 only) DH Motoring is now offering the first titanium retainer kit to market for the Honda Grom. Our titanium retainers are ma chined out of 6AL4V titanium to provide an extremely light and strong option for high revving engines. Weighing in at just over 3 grams they are nearly half the weight of the stock retainer. For motors that see repeated high RPM use, these retainers will help prevent valve float and also free up some high end horsepower! We run these on all of our race motors and they are recommended for any 2-valve motor that's revving above the stock limiter. Show more
