Spare parts are bit expensive but it is true that bike is good indeed. I would recommend if you can go fir used gb110s. Because one of my friend bought it new and he disliked the ride position for some reason. But to me it was quite fine and comfortable. And it all depends on personal preference.
Personally the price seems bit on higher side, especially the maintenance cost. So from my side not recommended.
But if you can afford please go for it.
