its been a few years since i have driven in Finland, but as someone that has driven and ridden in all but two European countries plus Russia, China and USA/Canada
i can say the quality of UK roads are the worst in western europe and a disgrace but not as bad as China or Russia.
this is why i no longer go for big wheels and low profile tyres on cars, having broken a number of alloy wheels in pot holes over the last few years.
The 790 suspension is what i would say on the firm side for road use, but as you found out can be bottomed out at the front but not as bad as a the standard forks on a speed triple, i am considering andreani fork cassettes currently
