RPMs

[rcturner]

Has anyone else noticed that in the Can Am sales literature, page 11, there is a picture of the RT instrument cluster that shows the engine turning 4450 RPMs at an indicated 55 MPH. My 2012 RT turns 4100 RPMs at an indicated 56 MPH. Did they do something to the gearing to raise the RPMs or is this another error?

RPMs and MPH are not specifically linked to a given speed at a given RPM . . . running up hill at 55 MPH will require more RPMs than running downhill at the same 55 MPH, for example.

If you have this situation, you have some serious clutch problems. The RPMs and speed are mechanically linked and not subject to variations based on load. The picture shows 5th gear.

Don't trust what you see in the literature as gospel. They are often artist's illustrations or photoshopped composites.

Scotty's point is a good one; however in addition, rpm's relation to speed depends on what gear you are in...

I would be in 4th gear at 55 mph, thus I would not be as low as 4450 or even 4100.

As a footnote: My speedometer indicates a speed that is higher (by a couple miles per hour) than I am actually going. I usually base my speed off my GPS for a more accurate reading of speed. Each Spyder's speedometer is likely off somewhat.
