OK I see where the confusion came from,
when you saif 'hard mounted' I read 'hard tailed' probably because I had just been on a thread about hard tails
My mistake
and Sporties outhandle Dynas for a myriad of reasons, including the dumbass way HD mounted the rear swingarm
I believe the Sporty swingarm is mounted to the frame, as it should be on a proper motorcycle

The guy in the video mentions an extra bushing or something that he removed in order to make the demonstration, so there is a little something else holding the swingarm. Roll Eyes Gotta give Harley that much. Roll Eyes


So they attached the swingarm to the engine, not the frame? Shocked

That's dumb! Tongue Tongue

Take a look at a Ducati Panigale. The swingarm bolts to, and pivots on, the back of the crankcase. That bike is pretty much a street legal roadracer. Top speed around 200 mph. I don't think they wobble.

There are a lot of different ways to make a motorcycle.

Okay! Okay! I should have been a little more open-minded to more creative ways of designing frames, but I bet the Ducati engine is solidly attached to the rest of the frame. Or is it? Huh Did Ducati use rubber mounts everywhere? I have some doubts that a rubbery flexible frame is a good thing, considering that some bikes have been considered dangerous with frame flex? Huh

Gotta beat on Harley! Grin

Ducati doesn't mount their engine with rubber mounts you can flex by hand, that's for sure
Yes you can mount a swingarm to the engine cases, I just think it's not a good idea, but race bikes often have minimalist frames, with the engine a stressed member and not much left for a pivot point
remember a race team will spend thousands to save 2 pounds, and they have mucho funds to replace broken parts
