I found this really interesting

And it fits so neatly into my autist obsession for manufacturer fanboyism and categorising things into lists!

Worth a watch.

Just to play Devil's Avocado for a moment, analysing the oil is a bit simplistic.

Okay, so Chinese "consumable bikes" i.e. the ride & dump 125 segment are not going to be great but the first oil change did always mesh with the break-in period for a vehicle. It's only in recent years that Jap bikes have effectively dropped the concept and manufactured engines to higher tolerances. It's all very well dumping on Ducati but the oil is doing what it's meant to do - hoover up the initial shrapnel.

What might be more interesting would be to take a new bike, get past the initial break-in (if it needs it) and then a dyno test. Ride and service for 10 years / 100,000 miles and then do it again. Of course accuracy pretty much goes out the window and it's a lot of oranges vs apples but I don't think anyone really cares about shavings in oil. People really care about how reliable the engine will be over time: will it go bang, will it still perform.

I'm no engineer but doing a dyno isn't going to tell you anything other than potential power loss. This guy has a series stripping a 100k miles engine and then measuring some of the wear. You have no idea what kind of life the engine has had though.

I think it's fair enough to dump on manufacturers who did worse when they charge high prices like Ducati. You kind of expect it from a Chinese bike as some corners must be cut to sell them so cheap.

"This guy..." ah yes, the notorious Matt Wink

Yes, dynos only give you a relative measure but I've always found it quite surprising (and I see this a lot in car restomod videos) that some old shitboxes will be down a few bhp from the factory spec a decade later and others have lost nearly half Shocked

Regarding Ducati though, their manufacturing output is a fraction of the likes of Honda so more of a boutique end of the market. And if they don't have the volumes they can't justify a robotic production line. Would you have a pop at Caterham 'cos your Vauxhall Corsa is more reliable?
