I couldn't find anything in the press release that said anything about "younger buyers." As for the bikes:
"The launch in early 2006 of the award-winning Daytona 675 supersports bike and the unique, 50s-inspired Triumph Scrambler have both contributed to Triumphs strong sales performance.
"Tue Mantoni, Commercial Director, says, "New models are extremely important to driving growth and we are very pleased with the reception of both the Daytona 675 and Scrambler, and the recently launched all-new Triumph Tiger. In addition, it has been great to see demand continuing to increase across the rest of our range, with models like the Rocket III, Speed Triple and our retro-styled modern classics appealing strongly."
Of the six bikes they mention, one is a cruiser and two are retro bikes. Then you have the Tiger, which I don't believe slews young. That leaves two models, the 675 and Speed Triple, which can be said to have "youth appeal" according to you. And again, nowhere do I see mentioned growth with younger buyers.
Perhaps the reason it wasn't accepted as a news item is that it contains more unsupported opinion than news.
