Just a couple month ago, Harley Davidson had over 10,000 parts on backorder. Indian has numerous parts issues as well. You are not getting the whole or straight story.
Trust me, I worked on them all until just a couple months ago. I am intimately familiar with the parts availability for just about every major marque as I worked on them all.
It's frustrating for everybody. Makers, dealers, customers. Welcome to the world post COVID-19.
The other problem, is that new Moto Guzzi dealers are notoriously stupid and unfortunately they are not required to purchase a stocking dealer basic inventory of parts and supplies. If Piaggio required a $20,000 initial inventory, then every dealer would have basic service and maintenance parts for all motorcycles for the last 10-15 years.
What the corporate idiots cannot seem to understand is that a fancy showroom does absolutely nothing to put and keep a motorcycle out and in operation. Basic well stocked parts departments and service departments, do this.
