Hi I have a Benelli tnt 600i 2017 model.
Recently I have changed the coolant and top up the reservoir too, but after riding for 5-10km, there are drops of coolant from the overflow pipe(not during ride as I keep on checking) but after parking in the garage and the next morning I see green spots on the ground

, and after a few days the coolant reservoir was at low, the bike odo is only 5000kms.
Please advice solution if any members faced the same issue.

Get your radiator cap tested. It may not be holding pressure.
Alternatively, is the coolant expansion tank over filled? If it is actually an expansion tank, there should be very little, if any coolant in it when cold. Don't be fooled by high/low coolant level marking. The Tornado has them but they should be ignored. Different if the tank is pressurised, like many cars, but very few, if any bikes, in which case it is called a reservoir, not an expansion tank, and will have a radiator cap on it to seal it.

A friend of mine had a MV i know each to their own...lol.. but the point is as previous comment that did very same thing once we parked up for a coffee came back to a small puddle...a call to the nearest MV dealer advised not to fill to the max mark as they did before the trip started as this would give room for coolant to expand when not being circulate when running...never had issue for the rest of the week we were away.. just did not top it up either...hope this helps...:oops:
