Governors

[ralph12345678910]

My dealer told me can am spyder on my 2015 sts are governed to 130 mph. This spyder has a 998cc engine, does anyone know if this is true. I will never get to this speed just wondering if it is true

There is a rev limiter that kicks in at about 9000 rpm on the 998 Rotax. You can do over a hundred, but you will not see anywhere near 130 mph. You would have to be going downhill, with the wind at your back and a afterburner attached to the back of the .

We have heard mostly about 105 - 115 mph. I have never tested mine beyond 90.

Similar results with the larger 1330 ACE engine. Rev limiter at 7500 rpm.

Ninety-three is the fastest I've had my Spyder and didn't check the tach to see what it was turning, but I would think that it's the barn door effect as opposed to the rev limiter when we get into absolute top speed in sixth gear.

[james199]

110 mph is the Max the law allows, but if you can find a flash programmer then the sky's could be the limit

[Highwayman2013]

I had our RT up to 96 with a headwind.

[cuznjohn]

i don't know about governor's, but all you married people riding 2 up most likely have QUEENS on the back of the bike

A big thank you to all who replied

Tell your dealer that he's full of crap... No governors; just the standard rev-limiter!
Why do they keep trying to sell this line of Bull-?

There's really only one super fun way to find out!

Rev-limiter or governor... tomato tomato...

1. A governor, or speed limiter, is a device used to measure and regulate the speed of a machine, such as an engine.

Basically a rev-limiter produces the same results as a governor, so what difference does it make if someone calls it a governor? Most adults understand what a governor does.

rs 2009 114 mph Nevada the road looked pretty darn flat.

The fastest my 2014 ST can do is 180kph, it governs out there. I guess for the majority of you in the states that would be just over 112mph. I keep wondering if you can re-set the governor to put more out? I'm sure my engine has more to give but that's my bike's pre-set limit.

[AY4B]

130??!!!

[AY4B]

Have you ever seen the bolts that hold your windshield on? I think they are made to snap at 130 and take your head off.

[youngers]

not sure about the gov`s , but what about the

lutinent governor of arkansas
lutinent governor of alabama
lutinent governor of indiana
lutinent governor of texas

Doubtful unless BRP made that changeable in the ECM with BUDS, which I'm sure they have not.
It's not bike speed limiter, it's an engine over speed preventer.

The original were set to 120 mph. I have had my 2012 RS with the 106hp engine up to 117 mph. They later changed to 100hp on the twin and don't know how they measure up. But have not heard of the 130 mph unless it's the turbo...

Do tell! Where does the law allow 110 mph?

[BajaRon]

I had my 2008 GS to 125 mph on the speedo one time with the very tiny OEM windshield and laying down. I put a somewhat larger windshield on and 115 on the speedo is the best I can do now. I estimate that the speedo is reading about 7% high at this speed so my actual speed was probably more like 115 mph instead of 125 mph.

There is no 'Governor' on the Spyder. Every engine has its limits. In this case the 998 runs out of power before it reaches it's RPM Red Line in 5th gear. So the rev-limiter isn't even an issue.

In fifth, sixth for the 1330, gear you're correct. But in lower gears the ECM does limit the revs. I've had my 2014 RT flat out stop accelerating at the the red line in 3rd & 4th gears.

That brings up another tidbit of info. A friend of mine has a 2017 RT. He told me max speed is higher in 5th gear than in 6th gear. Engine does not have enough power to get the same speed in 6th.

Have you found the same to be true for your 2014?

Can't say for sure, but it very well could be. The only time I've had mine up close to, or at, red line was while passing a semi as quickly as I could using 5th, and sometimes even 4th, which the RT doesn't do very well in 6th while pulling a trailer. Others don't agree but I contend the RT is short on top end torque. Your friend's comment goes along with that.

Sorry... you're wrong.
A rev-limiter is in place to keep you from damaging the engine by spinning it too hard.
That's all that it's supposed to do.
Try it in first gear: full throttle right as hard as you can.
Assuming that it works, and doesn't allow you to put the valvetrain into orbit: how can you call that a governor?
The speed is irrelevant...


Besides: these bikes run out of power LONG before they run out of revs. They're geared for theoretical speeds WAYYYYY beyond anything floated by us in here. They just lack the power to get there.

You are right. You're into a more robust portion of the power curve in 5th on the 1330 than you are at the same speed in 6th gear. So it pulls harder in 5th than it does in 6th. Think of 6th gear as an 'Overdrive'. It's made for cursing, lower, less aggravating (to some) RPM, and increased fuel mileage. Not for acceleration.

In fifth, sixth for the 1330, gear you're correct. But in lower gears the ECM does limit the revs. I've had my 2014 RT flat out stop accelerating at the the red line in 3rd & 4th gears.

Of course. That is what it is for. Otherwise they would not bother with a rev-limiter at all. In 1st -4th (5th for the 1330) the rev-limiter is a very important feature. It helps keep the pistons connected to the crankshaft!

Sorry... you're wrong.

You are correct. They are not the same thing. A governor is designed to limit the speed of the vehicle regardless of the engines capabilities. Like a Go-Cart at an amusement park. The motor isn't working very hard at all. But you just can't go any faster. You could put a 350 ci Corvette motor in one of those Go-Carts and it wouldn't get you any additional speed because it has a governor installed.

A Rev-Limiter is designed to limit the RPM of the engine to keep it from grenading (in which case you're not going to go any faster for sure!), without regard for the overall speed of the vehicle.

A governor is designed to limit the speed of the vehicle regardless of the engines capabilities.

That is probably the most common concept of how a governor is used, but a governor, strictly speaking, is not a speed limiter, it is a speed regulator. Think old steam engines. As the load on the engine increases or decreases the governor adjusts the input so the speed stays constant. Same thing with old gasoline engines such as the John Deere hit and miss motor. In some applications the governor was fixed in its setting, like the John Deere E engine I have, and in other cases it was adjustable like in an old Economy gas engine my brother has. Small gasoline engines in lawn mowers, pressure washers, etc., all have governors. Many are simply vanes in the cooling air flow that operate the throttle butterfly valve. The throttle handle controls the governor, not the carburetor valve.

We could properly characterize the ECM in the Spyder as a governor since the throttle sends a control signal to the ECM, and the ECM then controls the fuel flow to make the engine run at the speed we desire. The cruise control system is actually a governor.

So I will say, "Yes, the Spyder does have a governor in it!"
