I have a 916 sps and have covered 1,900 miles since full service including belts, by main dealer, last march. I change the oil/filter every 1000 miles [old habit] and have asked several people what they think is required for 2006 it has been in the workshop since they put the salt down and wont come out till its gone,i use the other bike during the winter months. i doubt weather it will cover 1000 miles, if that, before i take it to Spain[back of van] for my hols in July, roads to die for and no traffic. The U.K. in my opinion is now absolute crap and a waste of time owning a sports bike...me thinks new belts to be on the safe side but people tell me all sorts from there on... your opinion to totaly confuse me please ...thanks Steve..
