The top half of the gear knob can simply be unscrewed.
Thank you... I thought so, but it's really really hard, I didn't want to use cobra pliers, not to damage inferior part.
There's meant to be leather on there?
Yes I think so. we can see traces of glue, and it seems to have an offset for the thickness of the leather.
...i dont think it does 235kmh...
I'll try only on German Autobahn, and with 4 good tyres.
