is this real or just bs?

seems like a much easier route to just plug in a blue speedo converter to deristrict the bike :) i still havnt fitted my mph clock face ricky done me but tbh, iv got a blue converter too, be easier to just plug that in lol

Interestingly though i've found a blue-fox box that is the same as the SP unit but made by Blue Fox... maybe Liam would be interested in it :)

Cheers I did see that unit though it looks just like an HRC unit with a bluefox sticker over the top of it

My tuppenceon these SS boxes is that they are a tool for the regs at the time. SS/SP - road related class - so I would assume you were limited in running the std CDI. So if you then removed the speedo you needed something to stop the bike limping.

That is it...as simple as that.

I recall other people doing some testing a few years back and nothing was found ot be different. The Placebo effect asaide, I 'll be no-one could tell either way whether an SS box was fitted or not.

Surely this cant be the case as the NC29 & NC35 ran in the same class and both of these have HRC CDI's in their HRC manuals.

Also I read somewhere last night that someone thought that the SP unit was to stop retarding at high rev's in top gears??

[Neosophist]

It could indeed stop the retarding at High RPM / top gear.. some kind of manual / over-ride.. hence the spec's saying high-octane.

But again, without all the rest of the gubbins you wouldn't benefit from it.

It isn't a HRC SP unit with sticks I don't think





Wires are different colours for a start.. plus the sticker isn't raised where the HRC writing would be

is the blue fox one plastic? as the HRC one is cast alloy

[Yakama]

The HRC is plastic too and Neo I think the later HRC ones didnt have the raised HRC bit like the earlier ones i.e looked like this:



These ones have different colour wires from the earlier ones. I think its one of these ones with a Bluefox sticker on it

[Neosophist]

Interesting.

Is that a genuine HRC box? It's odd for a Honda unit not to have Honda written on it (unless it's on the back?) Every SP unit i've ever seen has raised decals. (different part numbers? I don't have the HRC manual here to check)

And the wires are still different colors between all 3 boxes! (Not that it means a lot)

Probably all do the same thing anyway.

[Yakama]

It doesn't say Honda or hrc anywhere but does have the hrc parts designation NKA stamped on the back

[porndoguk]

The HRC one i had was cast alloy! it was pretty heavy,

someone i knew also had one on theres that had road rash from a previous crash and exposed a lot of deep gouges in the alloy.

Did it expose anything else? like a load of potting (rubber) and a small resistor?!!!

no it wasnt that deep, i think Neosophist dismantled one in years gone buy and there was a bit more than just a resistor in there!
