V4SV ‘is now available’

They struggled to get 100bhp from it from what I recall. It also didn't live up to its name ie it wasn't light. Looked cool though. I've got pics of the carbon framed bike somewhere... that looked mega cool

I remember reading an article with SG saying the supercharged 650 would have 120 HP.
At the time I thought this was ridiculous, but with water cooling, and 10-12lbs boost, you can easily achieve 50% HP increase.
The stock 650 was to be rated at 80HP, so makes perfect sense.
But the extra heat will require a larger radiator, and an added inter-cooled.
Both of which will not add much to the bike's aesthetics.

I don't remember from the article that SG said it would be a modified Superlight, with a supercharger.
My assumption was that the supercharger would be placed on the Dominator, or other standard 650 model.
It would be a great exercise in engineering if they could do this and keep the package, light, compact, and aerodynamic.
That would be a real thrill, to light the fuse on that rocket.:p
 
Norton claimed 105bhp for the Superlight and plus 6bhp with the race pipe. Given the popularity and rave reviews of things like the Aprilia 660 and Yamaha R7, Norton were actually slightly ahead of the game with this bike.

The supercharged version was gonna be called the Superlight SS and the claimed 170bhp for this. But it was a Ltd edition £50k thing !

I don’t know why I keep telling myself the super light was a 1200. I’m an idiot. I believe I even said in another post it’s a 650.
But for some lame brain reason I keep comparing it to other 1200 cc bikes with 180+hp. Sorry I’m just dumb lol

Man that would be mind-blowing power, V4 with a supercharger.
They'd have to issue every owner a last will and testament along with the title.
Brings to mind the retched excess of Al Melling's Norton Nemesis from the 90's.
1500cc 235HP V8 insanity.

I’m fairly certain that the blown Superlight was claimed to have a lot more that 120bhp…

SG's supercharged 650 was 120HP, but Dr. Bob's id quite different.
Ah so, I found Dr. Bob's Superlight SS specs.
175HP, 350lbs dry.
Let the good time roll!

That’s the same bike. It’s the SG bike. TVS have never said they’ll produce the Superlight yet, and certainly not the SS version. I edited my post above to show the original articles and sales brochure.

That would indeed be a weapon and a half BT - don’t think there is another supercharged 650 on the market, although Kawasaki has been talking about it for a few years. I think the Superlight 650 SS was a Garner era project though? Sounds much more like Garner/Skinner than Dr Bob - noting that Dr Bob re-engineered the V4 down to 185 HP from 200+, to put a few safety margins/reliability back in I suspect.

My guess would be that they will include a Superlight to the model lineup - why would’nt they as again it is already mostly developed, would place a premium model in that weight group and oh by the way, is one beutiful looking machine. Gotta be a performer as well of course.

Good price by today's standards .
 
I don’t want a supercharged bike. Compressing air creates more heat. And heat is bad.
I’ll stick with naturally aspirated please and thank you with sugar on top.

Only if you're gullible enough to believe anything SG.
Says or claimed
IMO

Maybe if Hickey has a word in their ear?!
Then who knows??
Norton's first TT win in 30 years,
So win on Sunday sell Monday you say?
But win a TT And will sell 7days a week all year round!
I think TVS & Hickey should have a joint venture with the SL
And really put NORTON on the world map

In my not so humble opinion

As a laymen here, as the air is compressed 'downstream' from the carb/injection set up, putting aside the: 'cooler charge = better mixture = a GOOD thing' argument, would the inlet manifold and valves be subjected to any more heat than that which the exhaust side of things already sees??

Just asking :-)
 
Heat is not a problem provided the engine, and cooling system, is designed for it.

It is only excessive heat, ie over and above the design parameters, that is an issue.

You can’t really argue against the benefits of forced induction these days.

Perhaps the primary disadvantage on motorcycles is weight and packaging.

Another disadvantage on motorcycles is simply lack of benefit. Why bother making a blown 650 with 175bhp when you can simply have a 200+bhp 1000 ?

Sure you could build a 300 bhp blown 1000, but why ?

Exactly, just use a radiator designed to transfer sufficient heat to maintain safe engine operation, done.

Why climb Mt. Everest? Because it's there! A challenge to be mastered.
Why build a 300HP 1000, because you can, and it's pure wretched excess baby!

Tell that to a car when pushed to its limits on a race track. Heat can send them into a limp mode on some cars.

I can’t speak on a bike, but on a car I can. On a supercharged car, I have seen them and had them go into a limp mode when pushed hard on a race track. Sure on the street they were fine, but when pushed to the max or at my skill level, they have at times cut out and reduced power levels.

Fair point. But that’s still a design flaw isn’t it, the designers skimped on cooling knowing that 99% of buyers wouldn’t push that hard on a track.
The problem is not that all forced induction is bad, the problem is an inadequate cooling system.
