That is a really good idea. If I ever need to sell something to ppl on the Monkey I now have a blueprint!!If I were in his shoes, here's how I'd approach it.
I'd find the most attractive female downhiller in my area. Get her to post up some riding pics for about a week or two and get all the little racerbois looking at her hienie.
Then once her username gets known, get HER to start talking about this great training program that her and her man have been using. No affiliation, just a happy customer spreading some knowledge.
Not only would it be more credible because it's not coming from the source, you'd be assured some attention because everyone would be checking her thread for more tanktop pics.
That's just me though
