Guess they changed the '06's gearing!

[RTSR1/FJR]

I thought the motor and trans were unchanged for '06. Apparently I thought wrong! I've got 2 friends who bought '06's and both say @ 4000 they're at 80 mph. 4000 gives me 70 mph. Anyone else notice this?

 

[Fred H.]

There is about a 4 mph speedo error on my 06, and if I remember right, 4K RPMS puts me at around 78 indicated, which in reality is about 74mph actual.

They touted the change in the promo ****. Too, '06 owners are finding that their speedometers are off by as much as 5 mph (fast), IIRC.

Uh, hello? Bueller?

It has been widely discussed on this forum numerous times that the one of the changes to the 06 FJR was slightly taller gearing as announced by Yamaha. Get with the program, eh?

And what Fred said also. Can't necessarily trust speedo comparisons. And for all we know there is tach error also.

 

[FJR Gary]

At 80 mph indicated, my tach is at 4000-4100 rpm. Haven't checked it my GPS to see what actual speed is yet

 

[SkooterG]

Oh, and on my 04, I have been able to check my speedo error with my new GPS.

45-50mph - speedo reads approximately 1mph high

80mph - approx. 2mph high

120mph - approx. 3-4 mph high

160mph - approx. 4-5 mph high

My 03 was off by that much so it's nothing new.

 

[Fred H.]

Y'all are gonna force me to go out and start up my bike and ride it so I can document the RPM settings, aren't ya. Go ahead twist my arm.

 

[Fred H.]

Y'all made me go out and get bugs on my bike. I hope you are happy.

Here are the results, all in the interest of science of course...

Thanks Fred, nice table ---- as far as it goes, so when well we get the rest of it? You know the upper scale.

 

[War Machine]

Hey Fred,

How much is your GPS off?

 

[Warchild]

5--------------------78------------4K---------74.2

My crusty old GPSIII+ reads ~ 71.3 at 4000 RPM indicated, so while the final drive gear is obviously taller, it's not massively taller than the '03-'05 bikes.

Damn shame about the inaccuate speedometer on the 2006 models, though....

My '03 is dead nuts on with my GPS!

Er, what's wrong with this picture? You got variable top gear or sumpin'? 500 RPM to go from 66.3 to 75.1. Then, an additional 10 MPH for 500 RPM's from 75.1 to 85.6? Then 800 RPM needed to get from 85.6 to 94.6? I'm just not getting it...

It's an AE with a CVT.

 

[Groo]

He was only on impulse power for the lower part of the range... once the dilithium crystals kick in you gotta hold on for dear life before you hit ludicrous speed...

 

[Fred H.]

Well, there obviously is some error in taking the measurements on a moving bike at high speed while trying to hold an exact constant RPM while simultaneously reading three instruments at once. The parallax error on the speedo and tach alone are enough to induce error, as is the difficulty in holding the RPM exactly steady and the speed constant at 90mph. I did the measurements as accurately as I could.

Also, I do not recommend trying this above 100mph, as it gets very dicey holding it steady while trying to take precise readings off the gages and keeping the bike between the ditches. As the speed increased, so did my induced error.

 

[Groo]

Vista cruise works wonders for holding the RPMs steady (assuming you're on flat terrain) if you want to compare measurements...

 

[Rickster]

Does anyone have the spec'ed final gearing table? (The older ones are posted somewhere, I've seent 'em)

Takes some of the subjectivity in reading all the info whilst ridin' -- kinda hard to do accurately.
