Any experience of BMW boxers, and in particular their gearbox.

The best thing about the quick shifter on My BMW K1300S (with Scorpion end can) is the Noise you get when accelerating flat out and shifting up .You cant get the same effect doing clutch less changes .
52,000 miles with no problem from the up only quick shifter.
The gearbox is a bit clunky but ok .
