highest redline
#3
I googled Highest redline and found out that the R6 has the highest redline for a four stroke production engine.

The new R6 mentioned above is the highest ever for a production bike - 17,500 rpm IIRC? Having said that, peak power is still around 15k, but they gave it more headroom for track flexibility so you aren't forced to shift immediately after peak power.
I remember the old Lancia Delta Integrale turbos used to rev to 9k rpm which seemed very high back in the day. They also featured a limited overboost where it would allow extra turbo boost for 10 secs or something like that.

production car motor.... R/C car motors rev really fast... my old HPI .12 motor reved at 48000 rpm but i'm sure the sky is the limit on motors... as long as it was built to run fast...............

...I just guessed the RX-7 because I know rotarys should be able to spin faster because they don't reverse the momentum of any piece like a regular piston engine does...I didn't look anything up.

Stock RX-7 was about 7800 ish. The 2.0 S2000s were closer to 9k. This has dropped a bit with the bigger engine, but it is still pretty high.
The big difference with a rotary is that it produces power 3 times for every revolution of the rotor rather than once per 2 revs of the crank in a conventional 4-stroke reciprocating engine.

A new version will be released in 2006 having a 161 kg (357 lbps) dry weight, delivering 133 HP (97.8 KW) and running at up to 17500 rpm.
Wow!

When the Honda roadster came out, I remember reading about what a technological marvel the S2K's redline was. A big issue with production car engines, which motorcycle engines don't have to worry about, is one of emissions. A large bore, short stroke motor can rev much higher than a longer stroke motor. Problem is, when the bore gets very large compared to the stroke, fuel does not burn as completely which causes a car engine to fail emissions standards.

On a % basis, bikes are a lot worse than cars. By volume, it doesn't look as bad given that over half the vehicles being sold now are SUVs with > 4 litre engines.
