The parallel twin take over

[domarena33]

I'm a huge lover of V-twins in both sportbikes and cruisers but it seems the time of V-twins is over. The GSX-8R, the KTM 990 RC and the R7 to name a few. Yamaha even killed the R6 in a move to an inline triple (supposedly the R9) because of Euro 4 or 5 standards. I believe this twins change up is all due to European Emissions regulations as well. I'm gathering that they're still torque rich engines but with a flatter delivery of energy so there's at least a small delivery difference in the block layout between a I-2 and a V-2. Does anyone know what differentiates an inline twin from a V-twin as far as emissions regulations? Is it ease of production? Looking for a puzzle piece to connect the dots.

Money is always the answer.

New crate R6 engines are $5500. The more you buy, the longer you can stave off the decline of good bikes due to government manipulation.

This^. V twins are more expensive, more complicated, and more cumbersome than their V counterparts, both in design and in meeting emissions regs. SV is still homologated, but I expect that the 660 will become the dominant platform, looking at the numbers.

If they (sportbikes) sold well in the first place, they wouldn't be dying off.

He refused to understand that.

There are plenty of sportbikes being sold. That’s why we keep seeing new models.

I was referring to supersport (r6 and the like.)
