The last full production model year for the Dyna Wide Glide was the 2007 model year; the bike was offered in a 105th Anniversary Edition only for the 2008 model year. When the Softail Custom came out, that pretty much was the handwriting on the wall as far as the Wide Glide goes. I was working at the dealership in sales when the Custom came out, and I had a chance to ride both bikes. IMHO, the Wide Glide is more comfortable because the pegs were further forward and lower down than the Custom.
I always liked the Wide Glide, and hope that one day Harley brings it back.
