Although positioned as an economy replacement primary drive chain, the Japanese made KCM brand Duplex primary drive chain has delivered excellent fitment and service for decades. Is an outstanding choice when a budget is established and adhered to without compromising quality.

The 84 link endless two-row “Duplex” primary drive chain is manufactured in Japan to the highest standards for optimal fit and durability in the Triumph 6T, TR6, and T120 unit-construction models.

The primary drive chain connects the engine sprocket to the clutch chainwheel sprocket. A chain tensioner pad is adjusted to maintain the correct tension of the primary chain between the two sprockets.

The primary chaincase cover is removed to gain access to the primary drive system. Generally, the stator and clutch chainwheel must be removed to install the primary drive chain. The factory workshop manual instructions should be followed to ensure the job is performed correctly.

We also sell the Renold brand for purists here.
