Remember back when a literbike was a hoss at 119 hp? It has come a long way...

The way it wil work out is that a few years from now they are gonna pop out a liter bike that makes 200 whp, but after 10k mi a nice chunk of the bikes on the road are gonna blow their engines. Then the oem will fix the problem for a few years, but in their quest to keep up with the competition they will eventually build a weak engine.
Suzuki went through this cycle recently with the frame snapping issue, they did everything they could to shave weight until they created a major weak spot in the bike. Then they fixed it and now the weight is bellow that when they had frame problems. Eventually they just can't get rid of any more weight, unless they create some kind of anti gravity thingy.

the only place they really have left to gain powerwise is rpm. we already have solenoid driven velocity stacks and e throttles. next is going to be on the fly cam advancement and or some form of variable lift cam (i know already failed on vfr) and then pneumatic poppet valves. downsides besides added weight for parts are gonna be lighter more expensive internals. but maaan the first group to get it right...
