2010 was the first official model year. There were pre-orders of i think 250 bikes that were delivered to those who pre-ordered them in june/july '09. Those however were '10 models released early to those who pre-ordered. Your bike...if you did not pre-order it and you bought it new, then it was a regular '10 as opposed to a pre-ordered '10. Thats not going to tell you anything about the cam issue tho because triumph hasn't released any official info about vin numbers that are affected. They haven't even publicly admitted there is an issue.
