I can see how the title might be a little confusing, 250 was probably omitted from the title to not generate additional confusion about all the other 250 bikes it won't fit. 2006 Mastiff is the only one. It does state fits 2006 Mastiff in the description. Based on ya'll question, I went ahead and removed 300 from the title.
As the item description mentions, the difference between the 250 Mastiff and 300 Mastiff is just the diameter of the bolt holes. What bolts are on the 2006 Mastiff? Derek would know off the top of his head, I don't know what they used on the 06 Mastiff. 10-24 Button Head Cap Screws were used on the 300 bikes, that I do know. 06 Mastiff use 8-32 like the some earlier models?
I don't know if people don't see it but we tried to make it as easy as possible for folks. You can filter by year/model with a dropdown at the top of almost every page using the main drop down and just a general keyword search.
