Forget the next gen supercharged zx15 engine, or whatever they make. This should be in future bikes:

Incredibly small and lightweight at just 88 pounds, the engine could fit inside a suitcase.

They always leave out the part that tells you to forget it due to price.

Yes, but as with anything; mass production and time makes the technology cheaper. heck, drop the electric motor stuff and just give me the all petrol option in a bike. detune it to say, 300 hp. lol.

Who knows, maybe by 2025-2030 when Im too old to ride. lmao. Nah, Ill only be in my late 50's. A guy can dream, right?

A used 14 and turbo kit is only $10K...........no need to get too fancy :-)

you'd save almost 100 lbs from a zx14 motor, but it only revs to 7500. I need that scream!
