There's what looks to be a good 1995 on the market locally to me, want to act quickly! Reason for the brash title, my apologies.

I'm trying to figure out the early Fireblade's generation differences, and I'm a bit confused.

What exactly are all the differences between the 1993 900RR and the 1995 900RR?

Is the 1995 "fox-eye" model an SC28 or an SC33?



I initially thought 1995s were an SC33 due to the front upper cowl, but now see that I may be wrong.

Therefore, if I were to change the upper cowl and associated parts (fairing stay, mirror support, etc), I should be able to convert a 1995 into what looks like an early model dual headlamp SC28. Can someone confirm if this is true? I know the early front upper cowls in good shape are rare as hen's teeth. It appears the rest of the fairings on the 1995 match the 1993?

If I'm figuring this out correctly, I should be able to make my dream SC28 by just swapping front fairing parts (double adjustable front forks, magnesium head, etc.). Yes I know I'll have to do something about the paint and decals but mechanically I should have the best factory SC28 with my preferred dual headlamp fairing?


Any information greatly appreciated, sooner the better!

SC28 for the US encompasses 93-95.

SC33 for the US encompasses 96-99 (with changes in 98-99).

SC28 for the US in 93-94 were basically identical round eye blades, with no visual changes other than colors.

SC28 for the US in 95 changed to the foxeye upper headlight fairing, aluminum mirror stay, compression damping on the forks, the electronic sprocket speedo sensor, and the updated gauge set with the row if idiot lights versus the top and bottom one. Frame and swingarm were the same as 93-94.

SC33 for the US in 96-97 saw the new frame and swingarm, minor interior engine changes, TPS on the carbs, the same foxeye fairing as the 95, although the fuel tank shape was changed and the upper mirror stay now bolted to the tank mounts.

SC33 for the US in 98-99 saw a revised frame stiffness back to replicate the SC28, anther new upper fairing and fox eye headlight (more angled), a new tail section fairing, more internal engine mods, an all electronic dash set, speedo sensor on the crankcase, larger front brake disks (310mm), better front calipers, more trail, wider spaced forks in the triple clamps, and a more plush seating position.

All of these models 93-99 had the 16" front wheel, although different versions throughout the years.

I may be late, but I hope that helps you.

Thanks for the info doohan. Also, Honda reused many parts from 93-99 so it's worth looking at a part diagram to see what part numbers remain.
Doing so yields mounting locations for fairings from 93-99 being the same but tanks differing greatly. You could make a any one of those years look like any other without swapping frame or subframe. Again, tank mounting and shape differ greatly over those years but some mounts can be modified to fit but some shapes aren't compatible with other models.

This is true to a point, I have a 96 SC33 tank on my SC28 93, having had to modify the frame at the neck to accept the change in the front mounting point from 1 centered bolt hole, to 2 offset holes. Putting an SC28 tank on an SC33 frame however, would be going backwards in my opinion.

This is exactly the information I need, thanks. Seller went AWOL on me mid contact, guessing it's probably sold, time will tell.

I'm assuming these details aren't a full comprehensive list? Did the 95 get a magnesium head?

Were all mid and lower fairings the same all the way up to 99?

I can’t say for sure on the 95 getting the Magnesium head COVER, not the head itself, but the 98-99 definitely had it, as I have one and The word Magnesium is cast right into it. Someone else may be able to verify if the 95 had it. Partzilla has 3 different part numbers for it, so it possibly could be. Wikipedia says it did, but I don’t trust that.

The fairing question is tricky. I’ve never tried to adapt the 93-94 upper to 95-97 mids and lowers. I think just the 98-99 is the caveat. I don’t think the 98-99 upper will match 95-97 mids, but I’ve never done it so I don’t know. My gut feeling is yes, the 93-94 upper will bolt in right in place of the 95, matching the 95 mid panels. The mirror stay will probably line up too, but the gauge cluster stay looks significantly different on the 93-94, so you may need to find one of those.

I would just look for a 93-94 and then mod that to get you your adjustable forks and magnesium head cover lol

I powder coated my 99’s blue, says Magnesium bottom right. Can’t say I can tell the difference from my 93’s once they’re mounted, which I did in red.

That makes more sense. I read magnesium head somewhere and was thoroughly impressed as I've never heard of such a thing before. A magnesium valve cover isn't quite as impressive. So it seems then the major performance improvements were just the front forks. I was thinking they had a different motor (with a magnesium head). Supposedly the magnesium cover is 300 grams lighter, seems like a lot of expense for 300 grams. Guessing Honda wanted model year "improvements" to push sales in the final year of the SC28 before the SC33 came out.

Not at all interested in SC33s, was just curious about fairing interchangeability for used OEM replacement fairings down the road if necessary. I already have an '94 SC28. I'm actively looking for a "nicer" one and wanted to figure out if the '95 SC28s should be a consideration.

Thanks for all the help! Going to try and compile a comprehensive list of the '95 changes. I may after all purchase one and do the upper fairing swap. :laugh

The UK 1994 RR-R definitely had a magnesium cam cover. Our ‘94 is your ‘95

I personally wouldn’t get too hung up about the difference between the early bikes and the ,95/‘96 blades, they are very minor detail changes. My 93 rides just as well, if not better than my old ‘94. I really can’t tell much difference.

Tell us more about your tank mod.
Did you just drill and tap your frame?
Did the rear mounting position line up perfectly?
How does the shape of the tank differ between SC28 and SC33, if any?
In what regards was using an SC33 tank on your SC28 an improvement?

The SC33 tank is significantly "sleeker" than the SC28. In full tuck where your chest would rest on the tank is not as high as the SC28, and slopes more towards the seat. The sides also have more of a slope/angle than the SC28 making it feel a bit narrower as well.

Yes, the rear mount is the same, and with the bolt in the rear I eyeballed where it would rest at the front and drilled and tapped the 2 holes. I reversed engineered the 2 bolts from what Partzilla said they should be complete with the shoulder that fits in the rubber grommets with the special raised tube washers. It's not perfect, but one really can't tell the difference unless you're staring at it from an inch away lol

The one disadvantage (if its really that at all) is the fuel valve inlet and reserve tube. Due to the SC28 tank being taller, and me using an SC33 vacuum fuel valve as well (petcock), it lines up just a bit higher in the frame triangle on my SC28 than it would on an SC33. I modified the SC28's original black plastic "knob" to delete the huge plastic flange it had around the knob itself.

Overall the look is much sleeker, not as bulbus, and makes the seating/riding position less "upright" and the tank doesn't feel as "in your face" as the SC28 on did. Other than that, no other advantage.

Obviously it's easier to tell in person side by side, but here's some pics.

My original 93 I had 25 years ago: You can see how even the front of the tank by the triple tree was about an inch higher off the frame than the SC33 tank, and didn't slope back as much.




My current 93 with SC33 tank: The chest slope is far less, and not as tall

Gosh darn it! I've only gone and bought a Magnesium cam cover. Why? Why?

I blame 1/ this Thread, 2/ eBay (£12 delivered, who could resist?) and 3/ my complete lack of self control!

Now that it has arrived, it does seem to have negative mass .......

I am now of a mind to change the colour, inspired by Ian's rather fetching testarossa.

Colour is weight! Those 300 grams of weight savings is going to become 275 grams! :smile

At least your not hunting for a new bike like me. I'm still looking for a 1995...

So I'm on ebay looking at magnesium valve covers... (long story, seller I bought other items from has a few cheap)

95-97 share same part number. 98-99 have a new part number.

But they all share the same gasket, way back to 1993...

What's happening?

Is the 98-99 superior design, or just a design change necessary for accommodating the different engine? Will it fit 93-97?
The cover is the same I guess 92-94 in aluminum, then 95 went to magnesium, then 98-99 went to having "MAGNESIUM" cast into it and the internal crankcase breather was changed slightly (the rise by cylinder #4 ). I know that as I powder coated both of mine, and had a ridiculously hard time sourcing a gasket for the crankcase breather diffuser cover on the inside of the cam cover.

Those are the only changes as far as I know. All years should work on any year.
Thanks Ian. :)

Why are all your photobucket pictars blurry?

Was considering the SC33 tank on SC28 frame, hoping to reference pictars/ :S.

Fcuking Photobucket fcuking with me again because I won't "pay" them to host all my 4 thousand pictures. They started by killing the links, then reinstated them. Then put the watermark on them. Now they blurred them. I'm not paying them a dime.
