This always becomes a major source of confusion due to different VIN code standards worldwide.

UK/Europe and Australia does not use USA check digit at all so coding is quite different except last 6 digits and SMT at start is UK (SM) manufacturer Triumph (T).
UK / Europe ISO Standard 3779 system
Vehicle descriptor section (VDS)
The fourth to ninth positions in the VIN are the vehicle descriptor section or VDS. This is used, according to local regulations, to identify the vehicle type, and may include information on the
automobile platform used, the model, and the
body style. Each manufacturer has a unique system for using this field.
I reckon the 6th character 'C' is Rocket
US/Canada and Australia 6th, 7th, 8th code characters are the model type and fairly sure the 9th digit '3' is the number of engine cylinders while 10th digit '5' is probably shaft drive.
C00 = ROCKET III C01 = ROCKET III CLASSIC C02 - ROCKET III + ABS C05 = ROCKET III TOURING C06 = ROCKET III TOURING & AB
Vehicle identifier section (VIS)
The 10th to 17th positions are used as the 'vehicle identifier section' (VIS). This is used by the manufacturer to identify the individual vehicle in question. USA/Canada 10th is year, UK/Europe 11th is year. For Triumph motorcycles 12th-17th is a sequential 6 digit number.
Your 11th character, the digit 6, is 2006 model year in UK / Europe
ISO Standard 3779 system used in Europe and many other parts of the world. Mine is A for 2010.
Date year code is the 10th character for USA / Canada
FMVSS 115, Part 565 system.
This character can be either a digit or an Alpha character
