For TC19 I really wanted to do a motorcycle with an extended swing arm, I really like the aesthetic:
Here's what progress I made in LDD. I want the motorcycle to be as narrow and slim as possible, hence the V6 is positioned longitudinally.
And in real life. Because the elagonated swing arm produces higher forces, it's held in place by two small turntables, which eliminates friction on the secondary driveshaft.
Notice something odd about the transmission? Originally i wanted to use a 4 speed gearbox, but since so many people did it already, I decided to use something different.
I came up with a fully working CVT gearbox which uses two 2x2 cones and a rubber band to seamlessly change gear ratios between 1:2 and 2:1.
The following GIF shows how the shifting lever moves the rubber band sideways using a simple linkage with the drivline powered
