Time to start preparations ...
Lens: Rokinon 1.4/35 Camera: K1 Photo Location: home

Well, I can't deny the fact that I enjoy riding me motorbike much more than cleaning it

Next week it will get the 60.000 km service and new tires. 60.000 km is "just ridden in ..." for a Honda V4-engine. As a mechanical engineer who (long ago) was specialised in combustion engines I must say that this engine design is just fantastic!
Later in September I plan to ride to eastern Poland, close to the border to Ukraine. I'll visit an old friend and we plan to spend a week photographing great landscapes ... let's hope the pandemic stays somewhat under control.

Thanks EM!
It's great for long-distance travels, also with some occasional gravel roads. But too heavy for serious off-road rides
Shaft drive, relaxed seating position, enough power (129hp) and torque.
I've ridden more than 1000 km in one hit with just 2 or 3 re-fuelling breaks.

Thanks my friend!

Before I start I always try to memorise 2 important rules:

1. Tires down - rider up! Not the other way round!
2. Every leaning angle is fun on a motorbike as long as it's less than 90

Norbert, I think you've rewritten a couple of Newton's laws! Photos from Scotland are terrific.

Motorcycles and all vehicles...cars, trucks...have really improved in performance, durability over the years. I had four motorcycles from 1965 to 1968 and back then they were no where near as durable...or did they have the performance that modern vehicles have today. Today I have two motorcycles a '67 English big twin and a '78 Japanese big single...500cc. Our son has a '15 BMW G/S motorcycle and his bike is far more advanced than mine.

In the '60's it was not uncommon to have to look at rebuilding your motorcycle engine at around 30,000 miles, car engines at 100,000 miles or before. Technology marches on and I think with fuel injection, liquid cooling (motorcycles, other vehicles generally had it) , computer management, features such as DOHC, 4 valves per cylinder, variable valve timing, improved manufacturing techniques/processes, etc....significant strides have been made.

I wish you a great trip and look forward to photos. There is one area in particular I've always wanted to see in Poland. The ancient Białowieża Forest. Not sure if this is in your plans,

Well, having spent more than 30 years of my professional life to solve Reynold's equation I thought it's time to tackle something else

Thanks for your comment! My friend in Poland is now retired but was a professional landscape photographer for more than 30 years. He is living about one hour away from Białowieża Forest, so I sure hope we'll have a chance to visit.
And you are right about the impressive progress in engine durability. The progress in manufacturing accuracy is surely a main contributor, besides the greatly advanced simulation tools. I remember having to write a computer code in the mid 1980's to simulate the combustion process and heat losses in a Diesel engine from pressure measurements during one firing cycle of the engine on a test bed. It's hard to believe for younger engineers that you could do it with a computer with 32 kB RAM!! But I was so proud that my code reduced the calculation time from 3 hours to less than 10 minutes. Not quite the "real-time" simulation tools of today ...
