Some of the above comments are bonkers.
What I can't get my head around is why people have such ridiculous opinions on someone spending lots of money on a bike. I also can't quite work out the demographic of those that have such views.
Personally, I will likely never afford a £10k bike. Do I feel anything negative towards those that can? Clearly not. On that basis alone, my assumption can only be that the people with such views must be those that could afford to buy such a bike, but have chosen to use the cash in something else. Only to then be jealous of those who decided to buy said bike.
You can't have it all!
Another irony that I have noticed is that those, that pull a face at spending £10k on a bike, already have multiple bikes totalling more than that amount, and more, already...
