What is this melted hose under the fairing.

Evap purge canister drain. The canister is mounted to the left fairing. That tube should be tucked into the metal clip on the fairing. Looks like yours might be routed wrong as well.

Thanks onethump for noticing that. I looked at mine, just in case, and nothing is touching the exhaust.
found mine burnt right through as well. 129 km. not impressed

Same thing happened to me after taking my bike in for the first service. It happens only when the hose is not routed properly.

unnecessary hose and canister.

This.
The mechanic performed a modification of said hose and canister at the first service.

Thats the way it looks at my RC:

What makes me a bit confused is that I somehow see two hoses at ure pictures!? And I can’t find a 2nd hose at my RC!?

I really like this forum and its fun to read the all that interesting posts. That’s the reason I found this picture:

Now I am definitely confused: two hoses!
There is no way around I have to remove the left fairing and take a closer look.
Maybe someone here has a RC without fairing standing in the garage and can post or send me a picture how it should look like. Thx!

Not easy to see but the two hoses are put together with a Y piece. So I guess everything is OK.

Mine was burnt half through also due to the bracket falling off in the first two hundred miles.

Mine was fried also fwiw. Defiantly something to check.

Zombie post I know.
I had already deleted the evap canister and Y'ed the hoses together but found the bracket came loose on my '17. I think the vibration from the bracket actually rubbed about halfway through the hose which was hard to spot at first, but a bit of fuel overflow after the bike sat in the garage was spit out down the fairing and onto the floor enough to make the garage stink pretty bad. I wiped it off of the fairings, added some blue locktite to the fastener for the clamp and re-tightened it.
Unfortunately nobody around apparently has 1/4 in (~6mm) vacuum hose (2 Chicagoland DCs and 3 other stores) and all of the double walled fuel hose was too big and too stiff. I could've forced it through, but it would've made taking the fairing off a pain. I didn't want to use a standard vacuum barrel connector since it may runoff fuel and I didn't want that to melt it. I also would've had to probably flip the orientation of the hose since the barrel would be at a bendy part. Wound up just grabbing way more vacuum hose than I need off amazon for more than I should've had to spend on it. I'll just hope that the short period that fuel is dripping through it isn't an issue for the non fuel rated hose. I'm semi tentative as I don't want fuel running right by a hot exhaust but there's only so much I can do.
In case you want it the OEM part number is JY171605 on the '17 - on earlier bikes it appears to be JY171095 according to this https://www.eskayautomotive.com/pdf/2W/RC-200-390-SPC-GRAYSCALE-MY-17.pdf
