Yes, that was true three decades ago, but turbo and controller technology has changed dramatically in the meantime. Car tech has driven it, but it's trickling down to bikes. I'm expecting to see lightweight, powerful 2 and 3 cylinder turbo bike engines that put out power comparable to displacements twice their size.
Here's an excerpt from an interesting article on the Recursion:
At the heart of this prototype is a newly developed, 588cc, water-cooled, parallel twin with a turbocharger and intercooler tucked beneath the shapely fuel tank. Turbocharging is a simple concept. A small turbine, driven by exhaust gases, force-feeds pressurized air into the combustion chamber to boost power. Forced induction hugely increases the power-per-liter equation. Here Suzuki claims 100 hp at 8,000 rpm and a remarkable peak-torque figure of 74 pound-feet at 4,500 rpm. These numbers suggest ample power spread across a broad rev range, which would make this a fast and easy-to-ride machine.
