Hi Wilko,
If it's from a Dealer they should be able to check their records
to ensure all scheduled Servicing, Recall and Service Bulletins have been carried out,
which may ( depending on the VIN Number ) include a Main ECU replacement,
Additional Centre Stand strengthening bracket,
and possibly a Cylinder head "Upgrade" replacement.
If it's a Private purchase then hopefully the Seller will have paper records of these.
A few things to check that some Owners have had problems with :
Check for "tight" wiring around the Headstock by turning the handlebars fully
to the right and making sure there is still some slack in the bundle of wires you will see
running around the left side of the headstock.
Some Trophy owners have had issues with tight wires being stretched
and connections being pulled out !
Check front brake discs are not warped - Take a Test Ride and check for "pulsing".
Check the condition of tyres - if they are still the originals the front tyre is prone to "cupping"
and the rear tyre can go from looking OK, to the cords being exposed
in the centre part of the tyre after only a few more miles !
If equipped with TPMS - check that there are no TPMS "LOW BATTERY"
warning messages on the Instrument Panel.
The batteries are not replaceable and a new TPMS Sensor is expensive !
Despite the Handlebar switch being fitted as standard for Heated Grips -
the actual Grips are an optional extra.
If Heated Grips and / or Seats are fitted, make sure the Instrument Panel Icons appear
when they are switched on - they only work with the Engine running.
It has been known for the Grips and / or seats to be fitted, and for them to work,
but the Icons not to have been enabled in the "Dealer only" configurable setup menu,
which would need a trip to a Dealer, and a Fee to have that done !
You can also check for any DTC's ( "Diagnostic Trouble Codes" ) stored in the ECU
( if the Seller will allow you to ! ) ... Refer to this article on How To do that :
Servicing Data, Reference Info. & DTC ( Fault ) Codes - Post Reply #5.
At the end of that Post you will find a downloadable document
that explains the meaning of any Codes that may be stored.
Hope that helps !

Cheers and Good Luck

p.s. - If that's a Photo of the actual Bike, note that the rack on the Top Box
is not standard, so check how it has been fiitted and that all is "good" with it !"
