There's a tab on Brammo's web site, a number of posts on their Facebook page, and an entire forum on here devoted to Brammo's efforts in their racing program (branded Team Icon Brammo in recent years) with the Empulse RR that Brian mentioned in his post. That's their corporate effort. It has involved professional riders like Steve Atlas, Eric Bostrom, Shane Turpin and Shelina Moreda (did I miss anyone?) in recent years. It makes for some great reading.
They also sell the Empulse TTX, which is closely derived from the R, to a number of amateur racers (Arthur Kowitz for instance) and I've seen announcements of teaming up with some other race teams to race Brammo bikes in other series, but I didn't follow those too closely.
Brian has also raced on his own in the past (AFM for example) and has had a couple of project Empulse bikes (not RR's, but souped up R's and TTX versions). He's talked about those efforts as well, but often buried in other posts about what the team was doing. The bike picture that started this thread was another one of his more recent project bikes spotted at Thunderhill, and sounds like he's going a bit further than his previous personal project bikes.
