Your message leads me to assume that you don't know that a liter bike refers to the displacement, 1000 cc. It has nothing to do with the engine configuration, but the majority of the liter sportbikes are in-line 4's.
"V" engines have the cylinders in a V, like your SV650. They are usually twins, but one of the most heralded engines of all time, the Honda Interceptor series, is a four. Yamaha also has some V-4's in cruisers.
In-line engines have the cylinders in a line. Almost all of the popular sportbikes fall into this category, but there are also other UJM's (universal Japanese motorcycle) as in-lines.
Less common are opposed engines, where one cylinder (or bank of cylinders) are mirrored 180 degrees from another cylinder (bank). BMW has been using them successfully forever as a twin, the Honda Goldwing has always been opposed, starting with two cylinders per side, but has been a 6-cylinder for around 20 years.
They're all good.
Cruisers (think potato potato) are typically V-twins, with no horsepower, but with gobs of torque to get you up to 30 mph as you leave the biker bar.
Sportbikes are typically in-line 4's, with no low-end torque, but really scream at high rev's.
But there are no absolutes to engine configuration vs. performance characteristics.
