After being an engineer in the motorcycle industry for a short while, I get a chuckle out of the "high revs" statements. The V-10 is a relatively low-revving engine, though admittedly higher than the older V-8s that were around 15 years ago.
At the TT races one year in the 60's, there was a 50cc Honda 3-cylinder engine with 4 valves per cylinder. I don't remember the power output (probably around 10 HP), but it got peak torque at 18,000 rpm and peak power around 23,000. I think it had a 16-speed transmission to cope with the narrow working rev range. The rider spent so much time shifting gears with the clutch pulled, the bike wasn't very competitive.
Even the smaller mass-market motorcycles typically go over 10,000 rpm these days.
