Also agree that changing the oil more often is not going to hurt. I believe someone, somewhere, quoting those ever elusive statistics, said that the average motorcyclists drive about 3,500 miles per year. I do think we are better than average here, so, we put on a few more miles in our mostly less than 12 month riding season.
BRP's suggestion that every 9,500 miles or once a year, should cover about 97.356789432 % of the cases. If you are a high mileage rider, I would also recommend a lesser in-between mileage--just to be safe. I would probably do it about 6,500 or 7,500 mile intervals in the high mileage per season scenario. The first oil change on the 1330 is recommended at 3,000 miles and not 600 miles like we did on the 990/two cylinder engines.
My new 2014 ACE triple is going into the shop when the season starts in March/April here. It has 9,500 miles on it. Oil was changed at the recommended 3,000 for the first go around. It will be changed at the beginning of the season, and depending on miles driven, probably again in mid season. Will let you know, if you are interested.
