I own stunner since almost an year. My Strict take on it is don’t waste your money on this bike. You’d be cheated with the bike and Honda Service.
Engine:
1) Gets heated up quickly.
2) Struggles at higher speed.
3) Engine not smoother as compared to other models.
Looks:
1) Good, but digital consoles on other models you feel let down not even having a rpm meter.
2) Comfortable for people with height, Would take some energy to get on for shorter people.
Handling and Control:
1) Not so cool with the aerodynamics of the vehicle, you feel a drag. ( try it, when moving onto a flyover.)
Braking:
1) Disappoints, even on small inclined surface the bike skids.
Maintenance:
1) Burden on your pockets.
2) Spare parts are not easily available, (Try to enquire about any random parts and the dealer / service center would reject 5/10)
3) Service is the worst of all, there are limited service centers, the service provided by them is the worst when compared to others.
I would summarize "Worse is the bike, Worst is the Service."
