When talking engine generation, yes this is the 6th gen. 75-79= 1000cc, all naked bikes. 80-83 =1100cc. 1980 was the first year Honda offered the GL with Honda line fairing/ saddle bags/ trunk. First gen body style. You could still get a naked GL. 84-87=1200cc. 2nd gen body style and 84 model year being the last year to offer a naked GL. 88-2000=1500cc. 3rd gen body style. Now it gets a bit interesting. 2001-2017 1832cc gen 4 body style, sort of. Same 1832cc engine with a bit of a body change in 2012-2017. So you have 2 body styles in the 1832cc series, hence gen 1& gen 2. Now onto the 1833cc= body style 5. For arguments sake we should most likely leave out the Rune and the Valks, the slight panel changes and comfort levels.
