the Honda rune is a 6 cylinder boxer, for the TL.
there's only a handful of 8 cylinder motorcycles and none are Japanese made. exactly none is a boxer.
other than that, it's a completely stock GL 1800 unit, from '05.
it's one of the reasons it sold like a wet fart, it was extremely expensive, yet was a downgraded goldie as it had no fairings, radio, passenger seat and other features.
You can cruise in the world's most renowned motorcycle taxi for half of the price a rune goes for, when it's even sold... And get a few more horses to the lot as you get to pick a more recent bike.
there's something i don't quite get with this manga. One page you have a cub 110 shown, the next it's described as a cub 50, and it changes in various little details. the cylinder and head are 110 sized in many shots.
writing is significantly more consistent than the drawings yet... these cgi shots of the bike kinda annoy me.
it's as if the artist has never seen someone riding a cub.
