Hi All,

I'm a new member here. My wife and I recently took the MSF motorcycle safety course and then bought herself an S50 :smile: - pretty cool gal...

I'm really proud of how well she is doing, especially considering that she had never even driven a manual transmission car before this.

The problem is that she is short shifting, because she doesn't know what the engine should sound like for a given speed. My question is whether there is a chart available that shows engine speed ranges vs. road speed for each gear to help her improve her gear selection?

The bike makes peak power at 4000 RPM, which is far above the shift points listed in the manual. The S50's motor redlines at over 8000 RPM, which is something like 70 MPH in first gear, which I guess she is smart enough not to try. Just rev it up and go. She will very quickly learn to feel the shift points, rather than hear them or watch the speedo for them: the bike will pull very strong up to 4000 RPM, then power will start to fall off. The seat of her pants will tell her when she is past peak power, which is still only half way to the redline. So she is not going to over rev the motor...don't worry about it.
