I hear a lot of complaints about the R1200XX transmissions, clunking into first while at a stop, clunky shift from 1st gear to 2nd and to a lesser degree 2nd to 3rd.
The clunk going into first at a stop is unavoidable, a characteristic of wet clutches. One can keep the bike in gear, holding the clutch in. 1st to 2nd I find is clunky if you try to make a fast shift out of it. If you lay back a bit let the engine revs drop a bit then the shift is much smoother. Must be something to do with ratios, e.g. a tall first. Most of the other upshifts are fine. Just a thought.
