Coolant drying up?

[jaknai]

Hi there i'm actually posting on behalf of my brother . He recently got a super 4 version R, he travels almost everyday from JB to his workplace at changi airport using the bike. He noticed that the level in the coolant reservoir keeps going down on a weekly basis, he did a check on the radiator and the engine block and finds nothing that indicate a leakage. So is it normal for the coolant to dry up due to traveling to and fro from jb to the airport say 5 days a week? Thanks for your help

Previously I replace my original coolant with pouline brand, then found that the coolant level reduce 50% in a mth. After that I exchange it to castrol brand, that is very less coolant level reduce within 3 mths. I think the coolant density & effectiveness directly affected to the coolant level.

just recently i notice my coolant leaking when i was smoking beside my bike while waiting for it to warm up..

Sent for check.. realised the water pump is faulty.. might wanna check on that..

The leak wasn't that obvious but its good if you can bend down use ur fingers touch the portion beneath the engine to see if there's any leaks.. just my 2 cent worth..
