2017 T120 Should I Buy?

That’s just a bit of surface corrosion and will easily polish out, it’s no indication of any serious engine work. If you rode the bike for an hour (good that you did) and it was fine up and down the gears then it would appear to be ok.
I wouldn’t worry too much about it being there for 5 months, in the current climate not too much is moving in the way of used bike sales cos if it’s anything like here the showrooms are closed to physical viewing.
Can’t comment on price from this side of the ditch but if you are interested in buying the bike I would ask if there is any warranty included (and what is covered) and make an offer, if they aren’t selling many bikes right now you might just get a deal.
Welcome to the forum, good luck, stay safe.

 

Hi mate and welcome
As said that’s just surface corrosion
Probably washed and not dried/cleaned properly
Bit of TLC and plenty of elbow grease and it’ll look like new

 

Welcome to the forum
Get the polish out and enjoy it!

 

Welcome to the forum
You could ask the dealer to polish the casings as a condition of you buying the bike... make them work for your money

Yes welcome to the family. The cases all do that even my 900 that gets polished every week. Knock him down a bit on the price for work needing doing or ask him to polish the cases or fit the chrome replacements. They are nice bikes and yours seems fine but you must be the one who decides.

Looks like pitting to me and therefore will not polish out. It's not hard to keep cases good, a regular wipe with ACF 50 or similar is all it takes. Getting that way in 3000 miles suggests it's not been looked after. Why is that exhaust pipe blued?

 

With those pea shooter exhausts, I bet it sounds amazing
Happy riding

 

Hi welcome, I've got a T120 and have not looked back nor am i worried about gearbox issues.
There are riders and then there are riders, so if your considerate with your machine, ill be very surprised if it turns out to have gesrbox issues.

 

dont know if this link would help.

 

Not really, been down that road in another thread.

 

Welcome to the forum, @Perkybus! I'm a bit late to this thread but wanted to welcome you to the forum family. Great photo you posted for us of the Bonnie that you just bought! Hope you enjoy the bike and can polish out some of what ails the metal work. I lived in Florida for a year so know how humid it is and what the air can be like near the coast. Is it possible that some of the problems are due to salt air? That may be a goofy question but, hey, I live in the Arizona desert.
