Hi just had my MT07 first service and after much debate decided to fit new exhaust- needed a bit of noise to keep dozy car drivers awake, only been out once since being fitted and I feel it does make a difference, I love the bike being small great handling but just needed that extra, my last bike was a Daytona675 but getting old and it started to hurt to ride, I don't think for a minute I am going down in quality and standards even though my MT was loads cheaper. Has anyone else changed from a sports bike?
