My Trophy came with the heated grips installed, so I don't have much direct experience. But, I liked the grips so much, that when I bought a Honda CB500X, I had the Honda dealer order the heated grips for me to install. I did not realize at the time that grip cement was required to install them. so I had to order some and wait for it to come. I had to use rubbing alcohol to release the old grips, and work fast with the gooey grip cement to get the new ones on. I do a lot of my own work, and don't struggle too much. I will say the Honda ones were a pain to install, but some of that was due to the low cost nature of them. They had me notching plastic tubes that should have come ready to go. They had lots of sealing things up with electrical tape, which seemed cheap. There were way more pieces of harness than needed, with complex routing requirements due to lack of space in behind the headlight. Right when I was finishing up, a small bit of plastic broke and one of the grips fell apart after already being on the bike. Luckily I was able to glue it, and all was well, but I remember thinking "I should have let the dealer deal with this". Hopefully the Triumph kit is higher quality, which would make the whole thing easier.
