I know it could do much better with a REAL Super Slab gear. I'll keep it till I find something better but there ain't many choices .
They don't seem to provide overdrive gears in motorcycles like they do in cars. My Honda NT700 was turning about 5,000 rpm at 70mph, the BMW is turning around 4,000 I believe, and the little Ninja spins 9,000 rpm at 75mph (but that is understandable as the little 250 needs to spin to make the needed power).
Just about every motorcycle I have ridden feels like it needs a taller top gear - however they all are able to go several hundred thousand miles the way the factory gears them....so the engine operating in the 1/2 - 2/3rd redline speed doesn't seem to hurt the longevity.
