That’s a good summary, Lee.
I am a firm believer that a lot of test rides are too short a duration, especially when it comes to a different engine configuration.
I was always lucky that BMW, Park Lane let me have ‘test bikes’ for an extended period, not least as they let me run some bikes in for them. Likewise, a small Honda dealership in Stanford le Hope. The Royal Enfield dealership (again a small place) is just the same, as they let me take a bike out all day.
With the plethora of ‘Adjust this, adjust that’ now available electronically, nobody is going to learn too much in 20 minutes, I guess…. Especially if that 20 minutes, starts and ends on Park Lane,,W1. It took me to about Colchester on the B roads to ‘understand’ the K1600, way back in 2011 or whenever it was.
