I am not sure what has been done to the Norton. I know that it has significant brake upgrades and there are some modern mods to the engine. It has a lot tons of cornering clearance so I suspect tricks there too. The suspension is all dialed in perfectly and I bet the isolastic engine mounting of the Commando has been modified as well since the bike never wobbled or twitched or slid around the entire day on its narrow tires, and some of the supermotos did get loose in spots. I'd say that the Commando is highly refined using all the Norton tricks available. And the rider is aggressive and confident and no young kid. Still, Brakelate on his almost stock DR-Z400SM had plenty for the 750 Norton all day while the camera bike kept getting dropped when the pace hotted up. As they say, it is not the bike, it is the rider.the guy riding the norton was good! What mods were done to the norton?
