It's only available for 2 bikes though so it is VERY restrictive and of no use for the majority of HD buyers. I can see the #1 reason for NOT doing it is inventory. Stocking lot's of vendors parts in a Victory factory would present problems with stocking but vendors might go out of their way to support it. Additionally, teaching the assembly line how to install each vendor's part would take time and might create additional confusion on the production floor. One of the reasons Victory is price competitive is because they implemented the "Henry Ford" model of repetitive assembly of common parts.
To go from common parts to "whatever the F you want..." parts simply mean adding in-efficiencies to the line for...little (if any) additional profit. It could also alienate their distribution network who's RELIES on 3rd-party accessories in order to stay in business. HD can "force" their dealers to do this but I am not certain Victory would have that same leverage. BTW, HD dealer's are NOT embracing this with "open arms". Rather, they see it as simply "one more thing corporate is FORCING down their throats"...
It's not just any victory.... It's MY Victory!
