My car is 2023 MT10. It only rides 3700km and started coolant leaking. I checked that the surrounding water pipes were normal and there was no leakage. I guess the problem comes fromthe mechanical seal in the water pump...... Does anyone have repaired the water pump of the MT10/R1?    |

Looks to be leaking from the weep hole which means yes the mechanical seal is leaking (#6 that you have the box around). I haven't done it on these bikes but I've done plenty on others and it's not hard, especially since on this engine the inner part comes off.
This video is on an R6 as I couldn't find a 2015+ R1 video but it's basically the same setup:

I'm concerned about is why the mechanical seal breaks so easily, especially this is just 3700km new bike.

So it's definitely something that's common across bikes and happens. Yours is definitely premature at low mileage but there are issues that can cause a seal to fail. Both the radiator cap and the coolant overflow tank are designed to deal with the pressures that build up in the coolant system. If either are faulty or not working a correctly, the excess pressure will find a weak point which will usually be either a weak radiator fin or the water pump seal. The other major problem of coolant systems is trapped air which is why it's important to attempt to purge as much air from your coolant system. Water pumps cannot move air. air gets trapped in the pump. Excess pressure builds because a water pump cannot pump air through it and water doesn't compress but expands with heat. The seal is the closest and weakest point of failure.
I am by no means an expert or have any specific expertise in this. This is just stuff I've read and had been explained to me and I've replaced a few coolant pump seals. So my understanding of things can be incorrect but my basic message is to tell you to make sure the coolant system is checked and working correctly. Something as stupid as a pinched hose on the overflow reservoir can be a contributing factor.
