If your bike has a rev limiter, it will tell you. It will come to a point where the ignition will cut out and sputter.

I wonder what that is also. Here is a chart from the Haynes Manual.

The horsepower is shown at the 5500 RPM peak. Most of these will spin up to 8000 safely.

But I wouldn't chance it with my old engine .
Do you have a tach on it now?

Don't mean to hijack the thread --


BUT Inquiring Minds Want To Know.


How many of you VLX600 owners have hit your rev limiter?

I would like to know what year they started putting them on these bikes.
I am pretty sure my old 1983 basic engine doesn't have a sophisticated system as that yet. Not going to try it either.

That's another reason I was asking. Owner's Manual doesn't mention one but I've been told it's on mine.


In 13 years I haven't rev'ed it high enough to find it. And before I put the smaller sprocket I thought I was revving it quite high.

As said, the rev limiter will prevent you from going too high. It will not be "unhealthy" to hit the rev limiter every once in a while, but if you visit it often and hold it there, it could become an issue.
Now what the exact number is, I have no idea. On occasion I have hit the limiter, it seemed pretty high.

Darkside 185/65/15 rear tire
Perilli Route MT66 110/90/19 front tire

The biggest drawback to rev limiters is that they give a false sense of confidence to people who think that a rev limiter will prevent an engine from revving high enough to seriously damage or blow itself up. Nothing can be further from the truth.

If you're wound out tight in 2nd gear and your plan is to shift into third but you accidentally hit 1st, you'll most likely blow the heads off the motor and get to watch the pistons and rods exiting the case. Same with accidentally hitting neutral between shifts with the motor would out tight. Rev limiters only cut off fuel or spark. They DON'T limit revs.
