Warranty issue with a bike

[pits]

Bought a second hand bike from a Honda dealership, sold with a Honda warranty as the bike was still in manufacturer warranty.
The bike Honda CBF125 2012
Bought bike with 600 miles on the clock, had first service with Honda dealership, then second service with same dealership at 900 miles.

At 900 miles I highlighted some issues with the bike, mostly rust and a leaking rocker cover gasket.

At 1500 miles I brought it back as the rust was getting worse, it was still in warranty, the head bearings also collapsed.

Dealer submitted warranty claim

Honda refused to do anything, even the collapsed head bearings.

I've spoken to Honda Customer Relations who are also refusing to take this any further, told me to refer back to the dealer.

The dealer is on the same page as me, the bike has done 1500 miles in 2 years, dry stored in a garage, it doesn't go out in the rain, washed regular and dried off,

So the bike has done 1500 miles, the dealer agrees with me that it isn't fair wear and tear and should be honoured, they replaced parts for me on goodwill. This is what was highlighted on my 2 year old 1500 mile back
On the warranty inspection the following was raised
N/S frame welds on engine mount rusty
N/S headstock welds rusty
N/S Heel plate rusty
N/S gear lever rusty
N/S frame welds all over rusty
N/S chain tight links and failing
N/S rear shock showing signs of rust
N/S welds on genuine Honda top box rack rusty
N/S tax disc holder rusty
N/S Fairing bracket on tank rusty
N/S Tank side has large rust spot
O/S frame welds on engine mount rusty
O/S headstock welds rusty
O/S Heel plate rusty
O/S gear lever rusty
O/S frame welds all over rusty
O/S chain tight links and failing
O/S rear shock showing signs of rust
O/S Exhaust rusting internally
O/S Fairing bracket on tank rusty
Head bearings failed
Top yoke rusting along with wire clips
Bottom yoke rusting along with wire clips
Front wheel tyre valve threads rusty
Swing arm showing signs of rust
Centre stand pivot
Handle bar bracket paint wearing off
Rocker cover gasket leaking

Effectively everything that isn't plastic on the bike

So where do I stand, I am partly thinking about rejecting the bike, but really I want the bike fixed and rust free. Bike is financed, would I lose the money I have paid on it if I reject the bike? Sadly I am not the only person in this position either.

Also the dealer so far has been really helpful, we are both on the same page with the bike, it hasn't been said but perhaps indicated that the bike should be rejected.

Reject if you can. Get a YBR.

How long have you owned it?

[TPS]

At some point it's probably been left out in the rain for long periods by the previous owner.

I remember getting very similar issues with a Suzuki GP100 after riding it on dry, but very white (i.e. rock salt residue) roads, putting away in the shed (It was my #3 bike at the time IIRC) for a couple of months & finding condensation was beginning to do nasty things to the various metals... but I wouldn't expect to see that on a two year old Honda... where was it made? I'm guessing somewhere cheap, with cheap materials & coatings

I'm no bike expert, but I do know that you don't get rust without water/moisture.

If the rust is as you say, it must have been getting wet pretty regularly.

Even so, I wouldn't have thought that rust should be a problem on a 2 year old bike, even if it is kept in the rain. Who is your warranty from? You mention that the bike is second hand, does it have a Honda manufacturers warranty still on it, or was the warranty provided by the dealer you bought it from?

Honda dealer warranty from Honda themselves, there is a bike outside with 7 miles on the clock and rust running down the tank
