This is kind of a scary one, so I'll just get right into it. You like your rear wheel axle shaft, right? Even if you couldn't possibly care less about the greasy bits of your motorcycle, that's the bit that holds your rear wheel in place in your swingarm. It's kind of important to being able to operate and enjoy your motorcycle in a reasonable manner, which I'm guessing is why you bought the thing in the first place.
Ducati North America is recalling just over 10,000 Ducati Panigale V4 and Streetfighter motorcycles, over a range of model years, because of a potential fault in the rear wheel axle shaft on some units. According to the recall report that DNA filed with the US National Highway Traffic Safety Administration, a total of 11 cases of such failure worldwide were reported to the company, with none in the US market.
However, out of an abundance of caution, Ducati is recalling a range of affected bikes for total rear wheel shaft replacement, which will be provided free of charge to affected customers.
