Hello! I am hopefully going to be buying a brand new 2026 MT09 SP later this year (next month or 2) and I am very excited! I have been riding for almost 5 years now and have ridden a multitude of bikes. From z125 to a Honda rebel 500 and even a z900. I wanted to ask a few questions in regards to some things I want to add to the bike. I will be buying a full system exhaust for it but was curious if its ok to wait on flashing the ecu for awhile even with the new exhaust on. I was also curious what bar end mirrors everyone is using. I prefer the look of them a lot more to the stock ones. And finally what set of spools and rear stand are we using? I want to make sure im on top of chain maintenance and other general stuff so getting spools and a rear stand are very important. Anyways thanks guys and I will be researching this subreddit a lot!
