Stelvio 1200 - broken gearbox output shaft

[pauldaytona]

My Stelvio born in 2008 had exactly the same problem, the broken shaft, I was running at 10 mph when it happened, and then the bike blocked the wheel for a moment and there I was lying in the ground. The blocking was from the then loose part of the shaft locked up against the CARC housing. Almost 3000 euro damage to the bike. I have emailed the Piaggio service department and never heard anything.

When I worked in a motorcycle rental shop we got a shipment of 15 brand new 175 Hondas. They were great bikes, took a lot of abuse, but one broke a transmission shaft within the first couple of hundred miles. I don't remember if it was the input or output shaft. We started borrowing parts to keep the others going until it was almost a shell. Our main clientele was young zoomies from the next door air force base. They were really rough on the bikes, some of my main tools were an arc welder and and a pry bar.
