A popular upgrade combination from Colorado Norton Works for pre-MKIII Commandos is the Electric Start and 520 Final Drive Conversion. Besides getting the preeminent electric starter including belt drive, you’ll get a high quality 520 X-Ring chain which ends clearance problems and makes your chain nearly maintenance free.

For those able to bring/ship their bike to us, we have a special deal. We'll install both kits, take the removed parts in trade, and charge you very little more than it would cost you to get the parts.

cNw offers several options and upgrades which you can choose at cost – see the second section below.

While your bike is with us, we can offer additional options – see the third section below.

Call Greg at 703-200-4025 for more info or to arrange to be upgraded.  With lead times ordering parts, it's best to get this done outside the riding season! The cNw e-start kit can take up to six weeks to arrive if we don't have the specific one you want in stock. Everything else is quick to arrive if we're out of stock.
