Lowering the redline does reduce the horsepowewr. Either the rpm limit is
below the horsepower peak or it gets a milder cam. Less power either
way.

I didn't see "Yamaha" in the intial post.
My Yamaha YZF600R alternator spins 13,000+ rpm no problem (it is mounted
on the left end of the crankshaft). Kawasaki makes several 14,000 rpm
street bikes with alternators also spinning at crank speed. Once they
have gone to the expense of designing an engine like that it is stupid not
to finish the job by designing the accesories for it.
