I (eventually) got my letter from BMW this morning confirming NOx emmissions of 0.03g/kg for my 2001 R1150GS. No charge for this.
Interestingly...... the Rockster appears to have been measured with a slightly higher NOx output.... weird.
Could be simply a tolerance difference on the test, could be the CCCP was genuinely never fitted to the Rockster in any marketplace (a point for discussion?), could have been a damp/dry day in the lab!
