Keep Quiet. BDL Enclosed Belt Primary System.

closed-beltEven enclosed, your primary drive system will always be heard. But you can make it much more quiet if you go from chain to belt.

Thanks to the company “Quiet Clutch”, this enclosed belt primary drive by Belt Drives Limited is as silent as possible with a much smoother operation than a chain.

It is available as a conversion and retro fit for Harley Softail, Dyna and Shovelhead models. Manufactured with Kevlar on round dog aluminum plates, the new clutch significantly reduces clutch rattling. A unique basket carries 12 cylindrical, replaceable clutch dogs providing silk smooth transition, enhanced longevity and unimpeded performance.

Each kit includes a polished billet aluminum pressure plate secured by 9 shoulder bolts and specially designed springs. Shipped with BDL’s bullet proof Kevlar belt. Each enclosed kit is supplied with a sealed bearing for installation in the inner primary. For complete application information call 714-693-1313 or go to Belt Drives Limited.

    Enclosed drives are quite(-r) – but they are heavy. No free lunch it seems…

    Has anyone weighed the complete assemblies against each other as in the case of the above drive with ALU sprockets?
