I don't really see any reason for "fixing many errors"...
Just a few of them...
Check for the text symetry on the two side of the bike (once seating on the bike, the left side is good, but the right side is wrong).
Look at the leather mesh, it is full of errors.
There are missing sculptures on both front and back tire, and with their correponding leds.
Grid alignments are totaly unreal, especially the one from the back panel.
If you look closely to the dashboard, you will see that it is full of pictograms matching a car thermic engine.
etc.
Some of these oddities are even worse in version 3, look at the ridiculous front wheel direction, and tell me how you would drive such a bike?
