801 owners club

Anyone have a parts catalogue for the 801?

I need to order the black hose from back of the radiator to the water pump and the two clamps for each end.
Wait for Tom to read your request.
For sure he will find the right answer.
He knows everything about this bike
 
@Stevepilen, this may help.

The hose from radiator to water pump inlet on right hand side of the bike keeps popping off at the water pump inlet.

The hose is working itself upwards and the fluid is pissing out everywhere.

I have to ride with a pliers in my pocket now to re-attach the clamp and have 2 litres of coolant in the house to top it up.

Coolant leaks are also a common issue with the 790; many then use instead of the original rubber hoses some silicone hoses of higher quality; and also swap the original thermostat housing (which is made of plastic) for an aluminum version (from NiceCNC).

Edit: I deleted the link, as I'm not sure that the hoses will fit the 801 / just noticed that the hoses on the "early" and the "later" Duke 790/890 models seem to differ; the same applies to the hoses on the Adventure/Norden models. However, the "later" Duke 790/890 hoses should likely fit the 801 as well.

I had a coolant leak in my KTM 890 during the first 10k km. I changed the thermostat cover by the niceCNC that Tom is suggesting together with Samco hoses and it was solved. No other coolant leaks and I sold the bike with 46k.km

You shouldn´t have to do it yourself. I would deffo go with @Tom suggestion, but use Samco or similar hoses with good quality clamps.
Édit´ also sounds like you may have an airlock which is forcing the hose to come off. It´s hot hereat the moment, how´s the temperature of the bike? Ok?

After my first km ride with my new lovely 801, I found that I have a bad sensation by braking... I think there is something wrong with the brake disks. Even by low speed, it feels like the ABS is always in function. There is no smooth feeling in the braking. Always a hard point comming with the same frequence.
Picked up my bike today at the shop. They changed both brake disks under warrenty. Feels more normal now and much better feeling

So I had this hose and both clamps replaced yesterday. They couldn't find anything else wrong that could be causing it.

I rode 65 km's home and when I parked up I checked it again to see how it was. Still in position thankfully.

But one thing I noticed is that the hose is really hot to touch after a ride.

Could be paranoia on my part but would be interested to see if it is the same for the rest of the 801 owners.
