Just got a 2007 GL1800 with Champion trike conv. Rode 800 miles this week with the unusual warm weather Love the the bike, but do have question about the ride. Haven't been on any kind of bike in 30 years til now, it seems to ride rough over the raised expansion joints in the road. The front hits very solid and the back will at times bounce you around in the seat especially whenthe wife is on it with me. Have tried 5 to 25 pounds air pressure and doesn't make much of any difference. Glad to be onboard.
