You will hear lots of opinions here on what tyoe if oil is best for your ride. I believe it is similar to tire choices.....how do you ride and what have you done to the bike! My ride is strictly stock.....no performance upgrades....and I commute on mine and tour on weekends which puts lots of miles on my bike but none of the miles are "hard"!.....in other words I don't ride with my hair on fire! I use conventional oil but change it often. Change all 3 holes every 5k and engine oil every 2,500 to keep the oil clean.
If you ride hard and have performance upgrades going to synthetic is a good idea.....but for me.....conventional oil is fine IMO for how I ride......econimical because I put on about 12k miles a year and change it multiple times during the season.
