What RPM at 65 MPH

I'm breaking in a new Burgman. What are the RPM's at 65 mph?

At an indicated 65 mph the engine should be running around 6000 rpm. However indicated 65 is probably an actual speed of 60, as the speedometers are characteristically 10% fast. At an actual 65 (use a GPS) the revs should be around 6500...

If properly broken in, nobody will say it's only 400 cc.

Burgman 650 '04 Exec black (too much a scoot)
Last true 400.
Suzuki DL1000. (gone but still most miles)

I bought mine new and the engine revs were 5,900rpm at indicated 65mph. My speedo was 2 mph out with the new tyres according to my gps. So I was in fact doing 63mph. Now my bike has loads of miles on it and it turns at 6500rpm at indicated 65mph, and that's with a new rear tyre fitted just a couple of thousand miles ago. Clearly my belt is wearing which accounts for my higher engine revs. My speedo is still just 2mph out. So don't assume your speedo is definitely 10% out. Most are not (never seen one that is yet but clearly some will be) and it will vary depending on your tyre pressures, tyre wear, your weight, speed etc which all affect the wheel circumference. It's one of those variables. Enjoy your new bike and don't worry about it. These engines are designed to rev, not slog at lower revs. It has a low piston speed compared to a long stroke motor so it's not stressed.

What speed is related to 4,000 rpm's? I know that I must not go over 4,000 rpm's for the first 500 miles.

I'm still not riding it though. I had an infection in my right jaw. Had the tooth extracted and was on two antibiotics. That has cleared. Now, I'm having the same problem in my left jaw. Too sick to ride right now.

I would not worry about that.

For the 1st 500 miles do not let it idle for extended periods, do not go full throttle at any speed, and do not travel for extended periods at any single speed--then change the engine oil at 600 miles. It will be fine...

Agree with Cliffy. In fact Suzuki GB said I could use 5k revs during the first 500 miles as 4k is too slow. Do as Cliffy says with the throttle, vary it lots and it will bed in fine. 4000rpm will give differing speeds depending upon your weight, whether you are going up hill, down hill, giving it power, or just cruising. It will barely give 30mph if you hold the revs at 4k but if you give it some power (use the torque) as you accelerate, you'll find 4600rpm gives nearer 50mph. I kept mine between 4500-5000 revs for the first 500 miles, varying the throttle a lot and building up the speed and revs a little each day after 500 miles. It goes well and uses no oil at all under any type of riding.

DR Pulley Sliders 19 GM change things considerably.

I have posted test results (Dash Pictures of SPEED vs RPM) with the sliders for various speeds (indicated) after installing the sliders. Take a look at that data.

Not that it has anything to do with break in on a new bike with Rollers.

I think my last high-speed burst on I-10 here was 95 indicated MPH, at 7,000 RPM. With 19g sliders. It just hums along!

Sounds about right --- I rememebr from my test after 19GM sliders installed (posted results on here) at 80 MPH (indicated) was 6200 RPM (if my memory is correct).

Seems also that 95 MPH (indicated) was all she would do - same top speed as before the sliders, but at much less RPM (would not get up to 9500 RPM with the higher gearing - I think someplace around 8000).

PS: Can't say for sure without looking back at my test Posts of speed vs rpm after installing the sliders.
