Stock, not aftermarket. They don't look like traditional Brembo stuff. The Brembo logo is on the calipers and rotors though. The brakes are surprisingly good. Way better than the early generation Harley stuff.
After that video of Kyle Wyman I think it would be awesome to watch. I also think instead of riding raising their hands to signal, they should point 2 fingers at the ground at a 45 degree angle! https://images.app.goo.gl/b6PNRaCoaJh9JxxW8
I'm envisioning more than a few miscalculations coming into the braking zones and plowing into someone with one of these bikes under you as opposed to a more light and nimble sport bike is going to be quite the spectacle to watch
Worked at a Harley/Kawasaki dealer in '78. The stack of Harley brake service bulletins was thicker than the average Kaw shop manual. And Kawasaki had very thorough shop manuals.
Wow - only took them 7 months to pull it together after they got my memo. lol http://forums.13x.com/index.php?threads/the-powersports-industry-m-c-roadracing.361203/
Harley baggers run dual disc 4 piston Brembos up front and single disc 4 piston Brembo out back. They've used this setup for at least the last 10-12 years that I know of. They stop very well stock.
Been a while since I've been to an AHRMA event, but I always thought that the handshifters put on a great show. Rowdy. Unruly. Loud. Hairball, even. This could be really entertaining.
