Silverwings Top speed

Hello.
With all possible mods on.  How fast is it possible to make the
600 ccm Silverwing go ?

Bob

Bob,

Mods don't really help it go faster but quicker. My top speed stock, with Dr Pulley Sliders, or the J. Costa was still at 104 mph per gps.

From last nights ride I know 90 doesn't faze the squirrel in the cage.

I've done 117mph (by the speedometer) on the Isle of Man TT Course, between Kate's Cottage and Creg Ny Baa

Jeff, you're a bad-boy in my books now.
I only have the cajones to see 140 kph (87 mph) on mine.

The Variator and the exhaust without the baffles, and some say, the K&N air filter will make a difference in top speed.
If you want to substantially increase the top speed you'll have to start boring out the cylinders or add a turbo, or both. (Or nitrous).

Other things to consider are weight and the wind resistance of the windshield.
You could probably get a few more mph by switching to a sportbike windshield.
But what's the point?
It goes faster than the average Harley Police bike if that helps.
The BMW/Honda Police bikes are likely to catch you though.

Best way to test is with GPS.
I do believe that the Swing has a bit of a governer in terms of rpm's.
I had problems  maxing mine out (a 2003) in that I would get a cut out when the rpms were high.  Of course that might have been a fuel air mapping adjustment that needed to be made via power commander

To Test top speed without the factor of wind resistance, find a dynojet testing center where they have a rolling road dynamometer (or any dyno for that matter. There is also another name for this which alludes me at the moment.

My GPS said approx. 104mph like JeffR's. The speedometer was indicating somewhat higher but I didn't get a good reading on it since I was watching my GPS vary a mph or two up and down. Not to mention I was running out of 'previously scouted road'. My scoot had Dr. Pulley sliders which were, I think, 26gr. Not positive but I think that's what they were. I don't see how the weight of the sliders or rollers would make much difference if you're using the otherwise stock variator since any weight roller should have the thing wedged out all the way at that rpm.

The Book says 115MPH - I can't quite remember which Book.

I did state it was by the speedometer

Indeed but the title of the thread is 'Silverwings Top speed' and the OP asked how fast it was possible to make the Silverwing go not 'How fast have you made your Silverwing go?' or 'How fast has anyone heard that a Silverwing can go?'
What Honda themselves say in this matter seems relevant to me.

I'm surprised the OP asked this question as Norway has maximum speed limits of 90 km/h that's 55 mph, and 100 km/h which is 62 mph.

It's hardly worth the Costa the mods!   

Theres a youtube video of a guy going 185kph. My top speed 165kph, the swing was still accelerating but my nerve was decelerating . To sorta answer your question i guess the speed would be unlimited with enough money and engineering.

I passed a Harley at 140 km/h. He could have gone faster, but so could I. That's my top speed so far, I don't know what the SWing can do.

I think the 104 MPH is pretty close, but I have not gone that fast on it. I approached the century mark a couple of times and the wind buffeting had me worried so felt no point in going further.

Now my GL1800 is a different story...   

I just voted on something and not sure what?My big thumbs.lol On IPad .
Only thing I know is that it was this thread.

For GL riders my '90 1500 would top out very near 115mph and my '06 1800 hit the limiter a bit over 125mph. My C650GT is a bit faster at top speed than the Silverwing. I don't know where my K1100LT hits the wall... yet.

Norway easy to get speeding ticket---speed limits low---so how fast no issue there. Rode to North Cap there.

I say SilverWing top speed 95-100 mph good day, no wind. Probably fastest with standard windshield.

Hello Mr Bob

Our forum would be ever so honored to have a photo of your Silverwing at Nord Kap. I 'm sure that if that photo is well composed we could also connive the forum moderators to feature that photo on the welcome page. And given that midsummer is upon us you'd have plenty of daylight and Caribbean-like warmth to ease your travel

Tim

Bike was XBR500S Honda---I do have picture on way, but don't know how to send or care. Not computer geek.

With brand new belt and OEM rollers speedo hits 184 kms(114 miles) to the rev limiter.With worn belt round 175 kms(108 miles) to the rev limiter.With Dr pulley 28 gr sliders 195 kms(121 miles) with no rev limiter yet(speedo indication)

Don't care?
Maybe if you did care and would at least give it a try with the help of the forum mods or members, you wouldn't present such a negative, egocentric attitude. If you do want to post some pictures, I'd be glad to help you. Just PM me.

Will hold off for now....but will follow up.

My K1100LT showed 130 on the speedo on I-10 west of Kerrville some years ago.

Jon  :flower: 

Thanks for the info onf the LT, I'd read it should do 130mph, I haven't pushed it over a ton yet and that's by speedo which seems to be off about 5-10%. I know it's faster than my Super Cub was and a lot slower than the Mooney.

Hello.
The reason I ask is to maybe use it on track day at Rudskogen Raceway.
Might be funny to outrace those gixers on a scooter.
Currently using my 2003 Honda CBR 1100 XX for that.
We have the raceway evry thursday.
The speed limit in Norway is 80 km/t with exeptions for motorway class A+B 90 km/t and
some stretches on motorway class A 100 km/t.
And some stretches will get 110 km/t soon (They say)

For Big Bird on pictures----looked back thru pictures...have only a few-----trip to North Cap, found 2 or 3 Honda XBR500s, Pacifico fairing---have 3, 2 with snow background,,,then looked at 1998 in Canada---CB750 NightHawk &Kwik Camp trailer & dog....going to present SilverWing----all have the same pair of aftermarket CB750 type mirrors. They work.

So, do you want to share those pictures on the forum?

I'll go first.
That's me on the left in my hi-viz vest at a Ride for Dad fundraiser for prostate cancer research in Winnipeg. My Swing is in the centre of the picture. Notice the non-stock muffler. My buddy beside me owns an HD Electra-Glide Ultra. Nice bike, if you like a vibrating, clunking, beast.

Oh yeah, back to the topic. Silverwing top speed. Sorry.

I'm not really interested in your Silver Wing but I noticed you're wearing an Icon Mil-Spec Vest (complete with secret St Christopher medallion hidden away in the inside pocket) I wear one too!    

I sold my Icon vest this Spring.

I didn't want to look like you while riding  

I see everyone gathers in the parking lot for the 1 week riding season in winterpeg! Should be riding while you can!

:lol!:

29C out right now. 30C tomorrow. Going riding this evening and tomorrow. On Sunday I'll pull the battery and put the Swing away until next year.

Hitting top speed will be hard on valve shims.

If the rpms are too high Honda should have set the rpm limiter down. Top speed on the ground is a lot easier on the engine than running the engine up to max on the centerstand as some do.

Why?
They're made of special steel and are protected by engine oil. They're designed to operate to red line.

Oh just trying to talk someone out of riding wot.  

My SWing seems to get right up to 95-97 mph (actual estimated which is my spedometer reading minus 10%) with my 24g Dr P sliders and the GIVI adjustable windshield up (about 7600rpm). Can't seem to coax it any higher in calm wind. Maybe if I take my GIVI topbox off, lower my windshield, get a bit of a back wind, and find someplace where I am going a little downhill I can get it to 100 mph(actual) which is my goal before I leave this earth - which hopefully does not happen when I am trying to set my personal land speed record. 100mph sounds fast to me - but 97mph does not. My SWing is very smooth (on smooth road) at top speed but things could get ugly if I hit a bump, had to take an evasive manuver, or need to brake quickly. I feel good cruising at 70-75mph (good roads, good weather, light traffic) but anything above that is IMHO beyond my acceptable risk limit.

I had my 2005 up to 110 mph on the GPS. That was before adding the t-box. I also had the Givi Adjustable on it. Made sure all the bolts were tight and was not up at that speed but just momentarily. I will say this though, "It is an amazing machine even at that speed it was very stable." The gas sure goes through it when you push it above 65 to 70 GPS.

I am a member on several motorcycle forums and one common thread is "how can I get my bike (or scooter) to go faster?" Seems like we are never happy and always want just a bit more speed out of our steeds.

I told one guy on a CT90 forum (who was insistent on getting more than the stock 7 HP) to buy a different bike! Perhaps a Hayabusa?

Short answer, faster than common sense should allow.

I have done 90 mph easy.kinda stupid and unsafe to go any faster with a little bike like this; did 125 on my 1500 Gold Wing a few yrs ago and 135 mph on my 73 Triumph Hurricaine ..that was kinda stupid too. buy at 20 yrs old.???

I have bought a used SW 2009 model with 18.000 km on clock, today as I was going to visit a customer and the road was empty I decided to check top speed, the speedometer showed 190km/h and still had some to go, anyone know how much off is the speedometer?

If I'm not mistaken, speedometers in the UK are roughly 10% off, i.e. they over-read by about 10%.
According to Honda official figures the post-208 Silverwings have a maximum speed of 115 mph/185kph. I haven't seen figures for the early Silverwings.

Thanks mate

I must have the slower US model only does 105 mph. GPS and speedo the same. 8500 RPM's on the rev limiter she'll go no faster and that's with 26G sliders.

As a basic guide... The bike will only go as quick as the power to weight can over come, but mine hits the Rev limiter at an indicated 110mph, and the only way you can defeat that is to change tyre sizes given the top speed gearing is pretty much fixed.

And as the speedo is fed from the rear wheel, a larger rear tyre would either make it more accurate, or make it read under which is illegal in the UK.

I was watching a You tube thing a while ago about two guys with Burgman 650's fitting car tyres to the rear wheel.

Now this seemed to me to be a potentially stupid thing to do, because radial car tyres are designed to keep the tread flat and flex the side walls, plus the rubber compound is designed for the weight of a car, so I'd imagine the handling and wet grip would be quite scary?

But realistically, if 100mph on a maxi scoot isn't good enough for you, the best option might well be a Honda motorcycle fitted with the DCT system. I've tried them, no clutch, 5 speeds, almost thinks for you. The choice on those goes up to 1200cc and a pretty easy 150 mph+. If that's what you want...

Again, from my limited experience with Silver Wings, I do know that Honda "air flow" their bikes at the design stage. And I'd guess they would have "Air flowed" the 'Wing for it's top speed plus a bit more for wind conditions, if you push that envelope too much you might well get into trouble with air flow. And a larger rear tyre would pitch the front castor angle beyond what Honda designed as well, and whilst they are pretty stable as they are, lifting the back end too much would probably make the bike a little twitchy?

Pure conjecture here, but I think I know enough to know that messing with basic suspension settings can either reap huge rewards or tip you onto your backside when you are least expecting it.

I agree!

In the fairly dim and distant past I had my X9500 up to an indicated 100mph (nearer 90mph in actuality) for no other reason than that 'it was there'. I was very relieved that the end of the particular stretch of clear motorway* was approaching! I'm not proud of it but just saying.....

*(London end of the M3, inside the M25 - usually almost empty of traffic).

My Silverwings have been up to an easy 80+ in short bursts but Speed isn't top of my list; endurance at a good speed, comfort and enjoyment are..... and I get those in bucket-loads.
