Over the years, and every year since the fours came into the scene, the ante was upped. It's been 40 decades since the first four banger shocked the world. First it was the CB K and it was like that nothing could beat that, then the Z-1 appeared (that was The King - to me, still is), then Suzuki went four stroke and came out with the GS series, these were the first "civilized" monster bikes, then Yamaha junked their four stroke twins and put out the XS1100, shaft driven! Sg's Traffic Cops got these too and TP riders became si pei laolan. Then came the Suzuki Katanas, then I got too scared. I watched from the side as the Interceptors (these weren't inline 4s, theywere V4), Fazers, Ninjas, Fireblades and Hayabusas came one after another. But I still like the old kick-start two-strokes because these were the bikes me and my friends rode together.
As for the sounds, I don't know - can't really tell. But one thing for sure, I like them all.
Cheers!
Since you are a 2-stroker fan: a special question for you: Do you remember the Kawasaki 2-stroke Triples? Nothing could beat them in a straight line, on a straight road. But in the corners? That was a different matter altogether. Broken leg at the very least: guaranteed! Their handling was terrible!!!!!
