I have a 2014 XC and I love the look of the Gunner. I'm seriously thinking about helping my son purchase one.
As far a s accessories go I guess it depends on what you want to add. Grips, seat, handle bars, and wheels seem to be readily available. The same with engine dress up pieces. It's my understanding that it's a 106 and anything that you can get for a 106 will work. It doesn't matter what bike the 106 is in. The difference is when you go for Steel Tube or Aluminum frame bikes such as Air Intakes.
I'm sure someone on the forum will be able to point you to the goodies that will work for your bike.
Current Stable: 2014 XC, Honda PCX 150, 125 SYM Havana.
Born in the deepest jungles of India, I was raised by a friendly bear, until I was kidnapped by a pack of unruly baboons who taught me the finer points of swing jazz, all the while being stalked by an incompetent python and an evil but mis-understood tiger... Ummm, wait a minute, that's the Jungle book, no I was raised just outside of St. Louis, But...in the deepest jungles of a middle class neighborhood .
