Hi Em,
Negatives first:
The feet-forward ride position takes a bit of getting used to. (doesn't take long)
Cornering around tight bends can be quite interesting due to the rake of the forks. counterbalancing with your body on the outside of the turn cures this but is alien to how you ride normally. Practicing on quiet roads will pay dividends.
Positives:
You will love it.
It just purrs along, encouraging you to stay the legal side of the speed limits but able to 'blast a bit' when the mood takes you.
You will have to get used to 'old' guys coming up to you for a chat about how they had a Triumph in the 'war' etc.
You will build up your arm muscles with the polishing.
Fuel economy is good and you can do most of the servicing yourself.
Get one and enjoy.
