I hear you, but every service manual for every brand/model makes it on to the web.
That may be true, but as a forum administrator, I know that the owner of the forum is open to litigation if copyrighted material is made available on his/her forum.
Plus, we aren't about to reprint them and put them up for sale on ebay. We are all own Trophy's and paid a lot of money for them.
Doesn't matter, and that argument won't hold water in a court of law. You may think this sounds silly and unnecessary, but copyright infringement is very real, and I'm certain Triumph Trophy (the forum admin) does not want a lawsuit on his hands because you don't agree with copyright laws..
I won't feel guilty copying one for my personal use given I own the bike.
If you choose to do so, I would not recommend sharing it or talking about it online.
