Now for the "rest of the story"... (feel like Paul Harvey)
Maine is getting really screwed up with it's standards for
motorcycle inspections. Three years ago my trumpy shop put my bullet TORs on my bike and they have been happily inspected every year since. My stock pipes made my bike sound like a sewing machine. While I don't want something too loud, I want something loud enough to be heard. There are stock Harleys that sound louder then the TORs, heck, I think some Yamahas or Hondas are louder. So I drop off my 2007 Speedy to get inspected and it's 6K check up and they tell me they have to fail it because of the pipes THEY HAPPILY SOLD ME AND PUT ON. Because of the offroad sticker they now can't pass it for inspection. "Nice, why didn't you tell me that 3 years ago?" "Well, they have changed the rules"
Excuse me... I feel that there needs to be a grandfather clause here or something. Also if these F*N knuckleheads making up these rules want to ban loud pipes, maybe they should use a decibel meter and set X level as a max. If ones bike exceeds X level, too bad. If not, pass it. I agree with Gregger. Triumph bike labeling seems to reflect those standards for the bike in the UK where the brand hails from. I realize that their standards are more strict than other countries and therefore would need to label those pipes as such. To be honest I can't imagine putting the pipes that I have on my Speedy on a dirtbike
