Yeah it's true that these tires will never be used in cafe racing. In terms of function I agree that they are quite useless. However, given the fact that I will probably be riding this bike only once a week (Sunday), and also the extremely bad road surfaces / potholes / speed bumps / very bad traffic (I live in Bangkok), I will not be too concerned with its function as a mean of transportation. I will spend 6 days driving a car instead.
To add to that, you have no idea how things are like when it rains here (unless of course you happen to live in Bangkok), so the word "silly" is rather silly. It is actually not even valid since you do not have the slightest of clue the context of which I am talking about. The weather is also very hot and humid here even though it is WINTER (34c+) at the moment, so spending your time stuck in traffic may not be the best form of transportation. Oh and yes, rains = floods = even more f***** up traffic = riding cafe jetskis.
Riding a bike in developed countries where roads are well maintained, traffics are not too congested, weather is nice and cool, drivers respect the laws (and also actually treat bikes as another entities on the roads), authorities do their job properly, is an entirely different experience. Come to Bangkok if you have the chance, and don't forget to bring your bike over too. Would love to see you exquisitely maneuver your way through a maze of cars stuck in traffic that extends for about 500m - 1km, just to get to that red light at the very front so that you don't waste precious time (while competing with 200 other bikes doing the same thing).
Saying that I don't really ride my bike as a motorcycle is beyond silly. I wouldn't have started this whole project would I? Function before form? Of course I agree. But who told you it is the most suited function of transportation for where I live? I would say my passion for cafe bikes "as motorcycles" is no less than yours. For a place that is so unsuitable for bikes because of all the factors going against it, I still invested quite a bit on this thing even though I will not be able to ride it much. You sir, would probably ditch the thought of riding a bicycle and take the skytrain.
