They sell Rockets all over the planet and in the USofA, very few locales give a flying fart about emissions....California is one upstart that does, and there are a tiny few others. The rest rely on Federal regs, and I reckon Triumph can meet those with the right catalyst recipe, and tweaking the tune though I hope if it gets any leaner they will put refrigerant in the radiator! But whatever, the Rocket will continue to be built for the countries where it does meet emission regs, so long as they reckon there are buyers. But oh wait....UK is all but left the EU, so Euro emission regs may be moot except to the extent they want to sell any bikes in Europe. Frankly, Europe might ought to pay some attention to whether it may even EXIST in 20 years. As things are I see the landscape changing and changing wholesale and complete.
