Here is a photograph of a Triumph Thunderbird Sport fitted with chrome radiator end covers. These were not supplied as original with this bike but make a useful addition for those wanting to give their bike some extra bling.
These chrome end caps were fitted as standard on the Triumph Thunderbird (1995~2004) from 1997.
They will fit any of the Triumph Triples but are increasingly hard to get hold of.
Models they fit include: Thunderbird 900, Thunderbird Sport, Adventurer and Legend TT.
If anyone is interested, I have some spare chrome genuine Triumph radiator end caps for sale and will post more info soon.
Update: I have listed a pair of radiator covers for sale on eBay here: http://goo.gl/4Y1eWL
