Hi Helder, and

to the Forum !
No need to be apprehensive about this being your first Forum -
we are all quite friendly and helpful in here.
The Trophy is certainly a heavy bike ( 301 Kg ), but once moving it seems very light
and ( I ) find the Handling to be superb, with no problems like the one you describe.
All motorcycles have their own handling characteristics, and it may just be something
that seems different to you, but that you would get used to, however ......
Was it a Standard Model or an SE Model that you rode ?
Bear in mind that both have adjustable suspension :
Manual adjustment on the Standard Model, and Electric adjustment on the SE Model.
Check what the Suspension is set to, and adjust as appropriate for the riding conditions.
( e.g. on the SE you can adjust the Mode ( Damping ) for "Rider", "Rider with Luggage"
or "Rider with Pillion", and the Loading ( Pre Load ) settings for "Comfort", "Normal", and "Sport."
Instructions on changing the settings are in the Owners Handbook that should be with the bike,
( Page 54 for the SE Model ), or if it's missing it can be downloaded here :
Triumph Motorcycles Owner Manuals.Try the different settings on the same bend to see what difference it makes.

In addition to checking the tyres for wear, and the cirrect oressures ( 36 PSI Front, 42 PSI Rear ),
I would also take a look to see if the Suspension has been lowered, which
can affect the Handling, although it shouldn't have any major effect if done correctly.
Have a look under the centre of the bike at the rear suspension unit and it's Drop Links.
This is a Photo of the stock assembly, showing the approximate measurement
between the mounting points :

There may be different length Drop Links fitted, or a type with adjustable length
which will be obvious due to their design - with threaded sections and lock nuts.
You should also check if the front suspension has been altered - for example one supplier of lowering kits recommends lowering the front suspension by releasing the front forks
in their clamps, and raising them by a certain amount.
The easiest way to check this is to look at the top of the suspension legs.
Compare both to make sure they are both set at the sane height.
This is a Photo from my Trophy SE showing the top of the left Leg,
and how it should look if it has not been adjusted :

Hope this information helps !
Cheers
