I've has my 500 up to about 85 90 mph it can probably do a little more but without a tachometer I don't want to run 4th and 5th gear that deep and 6th won't do it unless it's downhill lol

You can backfigure out what your RPMs are, from your speed, at least in sixth gear. See this post I made a while ago.

The engine is rev limited to 8,000 RPM. The FP3 and probably the Harley Stage 1 download can lift that up to about 8500 RPM.

90 MPH in sixth gear is about 6000 RPM.

I don't know if my math is right, but it seems like 90 MPH in 5th gear would probably be about 6750 RPM, and in 4th gear it'd be about 8000 RPMs.

Someone who has a 2016+ Street, or any Street 500 or 750 with an FP3, could verify the speed at RPM calculations for us. Not a Street Rod though; it has a different size rear tire and that changes the RPM calculations. If someone wants to cruise along at 60, and report the RPMs at 60mph in 6th, 5th, and 4th, then we could update and know what the RPMs would be at 90 MPH.

If no one does before it gets warm around here I can try this but it's a little cold yet

Top Speed 500 & 750.

Don't really know the top speed because I'm not 16 years old anymore and top speed is not my goal in purchasing a motorcycle.


Based on running in the 80mph on the 750 at times and considering the throttle position at that speed, I suspect the top speed is probably north of 100mph on the 500 and definitely that on the 750.

Was wondering how fast you guys have gotten up to on your 500s. Im a fairly new rider and dont want to push too hard, I've been on the highway a few times up around 60, with all the wind it feels like I am flying. Thinking about getting a windshield.

Anyhow, feels almost like the engine might be straining at that speed, but with all the wind and outside noise I can't really tell. Curious as to your thoughts! Can you cruise at highway speeds (65-70mph) for long periods on the 500 without doing damage to the engine?
I own a Street 500, and i have no problem hitting 100 mph , with throttle and,what seems to be,lots of acceleration remaining. Rpm s are around 6000 at this point. Again, the motor sounds like it's comfortably muscling this out. Where's the redline?

As Gaijin mentioned above, his xg750 engine is rev limited to 8,000 RPM. Following the thread he linked to, my guess is that he used the tachometer feature of his FP3 and just ran it up against the rev limiter to get that figure.

I don't know if the xg500 is set up the same or not as this thread seems to mostly focus on the xg750. Does anybody with the xg500 care to repeat Gaijin's experiment? It looks like dabomb1000 volunteered to do so but may have gotten distracted once things warmed up enough to try it.

I vaguely recall another thread in which they mention the xg750a has a 9,000 RPM rev limit. I forget whether that was stock or by downloading a new map to a tuner.
