70-9989 - Triumph 650 750 Pre-Unit Unit Half Race Nitrided Exhaust Camshaft Cam E9989

Our favorite, the E9989 half-race exhaust camshafts are a fantastic option for a hot street bike, especially when paired with the E3134 inlet cam. These camshafts were originally fitted to 1970-1972 Triumph 650 models, but the profile was also offered as an upgrade for earlier engines under PN#s 70-5047 E5047 and 71-0041 E10041. This camshaft also features the tachometer drive in the end. From LF Harris in the UK, sold individually.
