The Damage what vehicle get just by driving around is way to high…. It was a good idea to match speed with damage, ok. But generally damage just by driving is no good idea.
Now you can drive some less kilometres, then a bike is broken even if you don’t crash or just only drive streets. Looks to me like it’s equal where you drive, if you drive your vehicle go broke. Wrote it before, just try to explain this to any Biker….?! I think every biker will laugh until he got a sixpack.
