What is the difference between the FJS600 and the FSC600

I believe the J refers to the Japanese model.

A couple of things from what I have seen. One being side relectors, red on the back and amber on the front fender on the FSC600 and don't forget about the lack of a power outlet on the FSC600 model. Could be a bunch more.

The FSC600 is the North American version of the FJC600. The FJC comes equipped with the power outlet in the left storage compartment, the H.I.S.S security system and wired marker lights in the headlight housing. Also the Asian-market FSC has 35 gm variator rollers.

Probably other differences also, but these are the differences I'm most familar with.

As far as I can tell looking at the microfische etc, the main differences are cosmentic and like a lot of bikes produced by Honda, they are given different designations in different markets, because of slight variations in specification. Over here in the UK its listed as the FJS 600 Silverwing, which made it a bit odd the first time I searched ebay in the US, not realising that it was listed as the FSC 600 over there.

For example my 1983 Silverwing is designated in full by Honda UK as 'Honda GL 650 Silverwing - D2E', the same bike in Japan and the US is listed as 'Honda GL 700 Interstate'. Oddly enough the engine is neither a 650 nor a 700, its a 673

in Italy, in Europe version FJS is commercialized

I have a FJS600, a german FJS600 Servicemanual with a very bad quality and therefor i bought also a FSC600 Service Manual in good quality.

The (technical) differences i can see on first look:
FSJ600 have a immobilizer System (HISS) thats not installed in FSC600
FSC600 have a evaporative emissions control system that is not installed on FJS600.
FSC600 have reflectors on front shock absorbers, FSJ600 don't have this.
My european FJS600 have also a power Outlet in the left box, i think your US FSC600 don't have this

Thats what i'm seeing on the first fast look to the books...

Another small but obvious difference is the UK FJS and US FSC 600 will have their speedometers in mph, and the European and Australian FJS in km/h.

Of course, UK Models (and all others which are driving on the wrong side) will also have another Headlights

Cosmic_Jumper mentioned 35g sliders in the variator for Asian markets. Would this give those SW better fuel economy? or just slower, more gradual starts?

Simple: Lower RPMs, slower acceleration and because of less RPMs also better fuel economy

Not so simple: Complete different shifting behavior, you have to test the effect...

Is it possible to get those 35g sliders in the US?

I'm in germany, but: Yes, why not?
Measure the dimensions of the original roller (i don't have it in mind) and go/surf to the next Scooter shop and order Rollers in that dimension with the wanted weight...

Not only Honda have this parts, i think you can get this from nearly every tuner like Malossi or Polini etc

I exchanged a few email with Paul Wu with DrPulley and he has confirmed that the FJS600 comes with 35g rollers at least in Japan.

On a post in silverwing.org, some where talking about lower rpm's using DrPulley's slider weights as opposite to the roller weights, and according to Paul, the rpm's will be a bit lower with their 28g sliders compared to the stock 28g rollers.

I'm thinking about going with the 32g or 33g sliders to see how it increases my fuel economy; I ride the SW to work every day and in the state where I live, a fast start is not my priority as bikes are not allowed to lane-split and move to the front of the traffic at red lights anyway...

I found another difference:
FJS600 have a switch for the lights that the FSC600 don't have

Indeed! One of those crazy EU suggestions that the manufacturers took up.

The older scooters were fitted with a light-switch.
My 2002/3 X9 had one but my 2005 X9 didn't although the blanked-off hole was still there. Blackfly's is a 2001 - before the EU thing came in.

I can't say for sure in this situation, but in some countries daytime running lights are an option, so a switch is necessary.

It's an option in Europe but the twats in Brussels (EU centre of operations where all the MEPs ride the gravy-train) put forward the idea of making it compulsory to have day-time lights.
The manufacturers either couldn't read properly and thought it had been passed into Law or thought they'd save money by not fitting a switch and hard-wire the lights.

At least it saves you from forgetting to turn them on. I have always ridden with dipped lights on during daylight hours. Sometimes my mate had to remind me to switch them on. Not anymore with more modern machinery.

Cheers,

One big difference is that the model over here has an S in the name, and no J. Overseas, you guys get a J, but are deprived of an S.
