You're right, it doesn't. But it adds to its character. Nothing about a trellis frame is antiquated. If that were true then I'm sure KTM would have sought other options for their new Super Duke R. The trellis frame part of the reason why Ducati was successful with the 916-998 bikes in WSBR. And its why Pierobon continues to make a trellis frame for the Panigale. How many championships has the Panigale won?A trellis frame doesn’t make it a Ducati...the engine, the sound, and the badge on the tank makes it a Ducati. A ‘21 Monster will still turn heads and have that “wow” effect because it’s a Ducati. Engineering progresses...otherwise we’d still be using carburetors, spoke wheels, and brake cables.
Engineering progresses you say...LOL. Well, do I have news for you! Ducati has literally made the same belt driven engine for the past 30 or 40 years with minor evolutions up until recently when they introduced the V4 engine to the mass market.
Using words like engineering progress does not mean you understand the dynamics of frame designs or the pros and cons of each type of design.
