False Neutral

When riding my bike home from the dealer (Ninja250R), I believe I experienced a "false neutral" when shifting from 5th to 6th. I shifted up from 5th and noticed no response from the throttle but the tach did rev. I shifted up again and it felt like a normal shift and I was moving along fine in 6th.
This happened two times in the 16 mile I road from the dealer to my house. I called the dealer and the service guy told me to give it a few hundered miles of break in and see if it keeps happening.
So my question is what causes a false neutral, and do I have a big problem on my hands or did the dealer give the correct advice?

Many Thanks!

It happens because the gears don't totally slide all the way into position and just freewheel next to each other instead of engaging. Bikes prefer good, strong, crisp shifts. The shift drum is not going into the next position, and thus the forks can't push the gears all the way over.

It's nothing to worry about just put a little more emphasis into your shift. And yes over time it should smooth out.

False neutrals are common among motorcycles. In the design of having a close ratio gearbox, and dealing with a multi-plate system, it is an occurance that comes with the territory. Make sure you are fully engaging the shift rod. A quick-shift will sometimes be the culprit. It sucks when it happens at full-boogie on the track.

I don't want to start anything here, but I changed to a better oil and it pretty much went away on my bike. You can try shifting a little harder too.

if you are wearing tennis shoes (for instance) you won't change gears as you normally would with riding shoes or boots... not trying to say anything bad about you just pointing out some facts.

When the bike is new and the clutch lever is not engage correctly you'll notice that it does this as well. Normally, delaers don't set up the clutches for the customers but in their defense, not everybody likes the clutch set the same way and many riders don't know the difference or how they want it set.

Setting your lever angles can help the way you ride your bike and engage your clutch and brake lever.

Do the breaking, change the oil and see if it keeps doing it.

I use this as my shifting technique to ensure position shifts.

1. Press foot against shift lever lightly (pre-loading the lever)
2. Clutch in
3. Raise lever
4. Clutch out
5. Lower lever

This will help ensure positive gear engagement.
