2013 was just 3 days ago

I wonder how motorcycles have fared? Motorcycle engine emissions seem to work different than car emissions. One thing I see a lot of is engines that were designed in the 80's or 90's (or 40's, if it's the right Royal Enfield) and are still sold now basically unmodified. You can buy a 2023 Suzuki DR650 right now today, and it will still have an air cooled engine with a carburetor on it.

But tightening emissions regulations have started to push out some of these engines. There probably won't be a 2024 DR650. The air-cooled Sportsters can't be sold in the EU now, and it won't be long before they're gone in the US.

I went from a 2009 Suzuki with the most simple of engines to a 2023 Harley with fuel injection, and overhead cams with variable valve timing. It has got to be a cleaner running engine, but I wonder how it compares to cars?

So, are they bigger and heavier, or are they equivalent?

Ive recently replaced the engine, but I hope to keep driving my 08 Speed3 for another decade. It's annoying having everything else in the road so much larger, but I don't want anything this size.
