Just a thought from a non 3 wheeler owner.

If it's the same amount of torque fixed in to a tubular frame (chassis) is it down to poor design or poor construction, or both....?

I just wondered.🤷ðŸ»â€â™‚ï¸

An unfair comparison Julian. HD engines are not only smaller generally, they have a degree of balancing. The 2 litre X wedge engine doesn't, it's just a raw torque. Just watch a Harley turn up at a meet and observe engine at idle. It's so smooth and soft by comparison.
