A couple of my newer bikes have rev limiters on them as does my RT. That's more for engine protection than it is a speed limiter. Not all bikes have the needed horsepower to get to the rev limiter in the higher gears. The wind resistance is just too great for the available power to overcome. Then there was this; A gentlemen's agreement was made among the major motorcycle manufacturers to limit the speed of their machines to 300 km/h (186 mph), starting with 2000 models. That was agreed upon for the FEW motorcycles that could actually reach that speed and of course the Spyder isn't one of them. Not even close. I have read where some countries in Europe are considering technology on new vehicles that would limit them to the posted speeds.
Yes, it is limited. That's why you can reach max allowed speed in 5th or 6th gear. It can be raised by tuning the ECU.
Don't know.
I do know my '21 RTL will easily and smoothly run 95mph in 6th gear with 2 riders but haven't had the need to try and push it above that... yet.
I don't really know for sure about the 20+ Spyders, but I do expect they'd be at least similar to the earlier models :dontknow: and for those made earlier than that, there's been similar threads & discussion both here & elsewhere, & IIRC, there's even vids showing this in action - I'm pretty sure they're not actually 'SPEED limited' per se, it's more of a Wide Open Throttle Limit that effectively achieves the same thing! :lecturef_smilie:
So unless you've had your ECU upgraded to remove this WOT limit, the throttle just won't remain Wide Open for very long before it cuts back a bit - and that means that while you can get the engine to accelerate pretty hard, you simply can't hold WOT for long enough to continue increasing road speed until you reach the potential maximum speed the engine's power/revs should be able to deliver when balanced against the dirty great wall of air our Spyder's hafta push ahead of them & all the other 'natural' restrictions that team up to limit top speed! :banghead:
So AFAIK, NO, they're NOT Speed limited as such, but there's more than one way to achieve that end, & BRP have found at least one of them! :rolleyes:
Drag force does vary with the square of the speed, but power needed to overcome that drag force varies with the cube of the speed.
the power needed to push an object through a fluid increases as the cube of the velocity. A car cruising on a highway at 50 mph (80 km/h) may require only 10 horsepower (7.5 kW) to overcome aerodynamic drag, but that same car at 100 mph (160 km/h) requires 80 hp (60 kW).[16] With a doubling of speed the drag (force) quadruples per the formula. Exerting 4 times the force over a fixed distance produces 4 times as much work. At twice the speed the work (resulting in displacement over a fixed distance) is done twice as fast. Since power is the rate of doing work, 4 times the work done in half the time requires 8 times the power."
well that's how i remember it from my drag racing days back in the 80's and early 90's.
My previous bikes have all been speed limited and I was curious if the Can Am was also limited, not by rpm or wind drag , just plain old mph. Two harley's were done at
107 mph, 2018 goldwing was 112, no matter what gear they were in. They would accelarate strong to the mph and just go no further.
I helped developed the ECU flash that is I believe the only one available in the USA. Simply put BRP only allows the RT platform to reach 105 to 108 mph and the F3 sport to reach 112 to 116 MPH. Yes some riders report under optimal conditions, (going down hill) a little higher MPHs. That is why I don't post this info it just starts a pissing fight on the forum.
We had hundreds of hours trying to unlock speed restrictions and found that the ignition ECU, Transmission ECU, and the dash computer all are active in controlling top speed. We gave up as all 3 components would need to be flashed together. It was calculated that if Can-Am unlocked everything and gave us 150HP plus, as the motor is capable, the RT platform would reach 128 to 130 mph and the F3 Sport could break 140 mph.

There was a guy reflashing the new Goldwing computers who had good results, but he decided to stop doing it due to the govt coming down on shops modifying vehicles, whether it was bikes, or trucks, or cars. It could be very expensive if they are found doing these modifications...
I didn't know that the RT was limited to 108 mph by the ECU. I had mine up to about 108 for a very short time and thought it just ran out of HP, pushing that big barn door front end through the wind at that speed.Quote:

What's your hurry?
Just my opinion, I could be wrong, and I'm sure someone on this forum will be delighted to tell me so.
The flash is for making better acceleration performance in the RPM ranges that everyone drives in. 25% more power from idle until your personal preference for RPM shift points. Where it is really noticed is coming up an interstate ramp 2 up and how quickly you get to your 75mph. And, just like the pedal commander the acceleration happens with less twisting of the throttle.Quote:

For my 2021 RTL I have no intentions of putting a sway bar on, changing shocks, or getting the ECU flashed. My RTL is cushy plush in all riding conditions. For those who like their ride as is, you should really consider the Pedal Commander to reduce your throttle roll on by about 40%. Hard to explain, but it is addictive having shorter and quicker throttle response.
Dennis
The simple answer is yes, as pointed out by several posters.Quote:

Is that your parking brake indicator illuminated?Quote:

At https://www.auto.de/magazin/can-spyd...erheitsfimmel/ (a german test magazine) they also write about the Speed on a F3. They tested it at 198 km/h (123mp/h). That speed sounds quite realistic as cars with roundabout 120hp don't hit much more than 200 km/h. The Alpina B8 GC needs 620 hp to touch the 200mph. ;)
yes because i was parked while i was gettin my $1500- ticket for speeding.Quote:

We have never pushed the limits. Currently, posted speed limit--plus no more than five mph. On quiet country roads, we like to putz along at around 40 mph. Saves gas and we enjoy the great scenery.
Our 19 and 20 F3L's will do at least 80. :bowdown:
A bit off topic...but the latest issue of Rider shows the "new" 1100 cc Honda Rebel with fairing and saddle bags. Looks like a H-D Road King. Very nice, 27" high seat, semi auto tranny available, weight around 500#, and in a beautiful burgandy red. $11,299. Hmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmmm!!!
Take it out and kick it in the guts. Limited to the machines top speed or your courage. If you decline that well what difference will it make?Quote:

(Awaiting my new 2022 RTL. Which will never, ever go 108 mph.)
ummm...Rev Limiting and Speed Limiting are two different things....
It's speed limited.Quote:

I had the same top speed on my 2022 S2S.
My F3s as seen 100 mph, and was still going when I backed off the throttle.
And here is a tip on how to make your spyder go faster, without any special tuning.
For you Americans, change your speedo from MPH to KPH (if they still allow you to do that). 62 mph will now show up as 100. Don't tell your rider. :roflblack:
Now that reminds my of a true story from about ... well a few years back.
I was looking to pick up a new to me 2nd hand bike off a bloke.
Looked it over, test ride OK. Yup no worries, but if ya smash it ya own it. Yup deal.
So off I went.
Rode it a bit and began thinking this bike is really windy to ride and dosnt really corner as well as I thought it would.
Almost back to the starting point and pooteling along. It dawned on me. :duh: The speedo was in MPH.
We have had speed limits here posted in KPH since 1974 here, and decimal currency in 1967.
I still stand by my comment. Post 22 here.
Take it out and kick it in the guts.

One up, my RT LTD seemed to get quite front end light on a "private road" speed test I once gave it. Here at 5,000 feet, the drop in power means 105-108 mph is seriously optimistic though.
With the aerodynamics of a small house, it might look very slippery, but I rather think it doesn't do a very good job of getting negative air pressure underneath it at speed. No ground effect in other words.
Whilst it cruises very nicely in the 70+ speed range, it definitely doesn't seem so aerodynamically planted at much over 80 mph on anything other than very level pavement.
Being essentially a cruising machine, whether or not it is speed limited is probably irrelevant. Actually, it isn't really relevant even for liter plus sports bikes unless on a track day. If you are un-happy that your bike is speed limited to the 186 mph "standard" I think your riding days are going to be curtailed either by the court system or by an almost guaranteed seriously shortened life span.
Much beyond 100 mph and my old brain can't process information quick enough on the street. Too many variables to manage with not enough time to process them all.
Many, many years ago when I was young, bikes never seemed fast enough, nowadays when bikes are seriously quick I'm too slow to take advantage of that.
Yep! Every vehicle is limited in some way. Just depends on if you want to live or Die dangerously!
They definitely are speed limited in reverse. 9 MPH max!Quote:

Am Now Googling Longest straight steepest downhill stretch of Interstate in the ....... Though I suppose if I lost 100 lbs, my RT would hit that limiter.....;)
It might not be the longest but there is a nice downhill straight stretch on I80 west bound from Summit Park down towards the Salt Lake Valley that’s pretty steep. Also eastbound on I70 coming down from the other side of the mountains from its start at I15. Both are in Utah and get pretty high up before descending. The elevation of course means a lot less power but they do feel like driving it off a cliff. There’s some pretty good descents northbound on I15 too, just north of the I70 turnoff. I70 in parts of Colorado are fun too. The elevation gets you there too. Heading west to Nevada has challenges between the ranges of mountains.Quote:

Perhaps looking up truck run off ramps on Google Maps might give some places to start.
