hornet 600 changing wheel sizes. discs question...

[m0l0t0v]

So ages ago I bought a 17" front with no discs for the hornet, hoping the discs I have would fit. The hornet has sp1 calipers and discs and are absolutely amazing so don't need to change them and would like to do so without having to buy new discs.

I have swapped a disc over and the bolt holes are flush and sits absolutely perfectly, but there is a small gap been the inner disc ring and the wheel hub. Is this an issue, or since the disc is held by the bolts does it not matter? My mind is saying it's fine and a couple of friends believe so too, but would like confirmation from those that do know. The gap itself is like 3/4mm thick.

Like I said, the disc suits flush to the bolts and there is no forcing of trying to get the bolts in at funny angles.

Quite a few people have done it. I haven't, but may do one day.

IIRC it needs the fireblade discs or spacers or something or other. Not just a straight swap.

The 16" Discs do not fit the 17".

17" wheel and discs are a direct swap for the 16" using the original spacers.

AnPhonEh is correct.

Well, the discs do fit...

The discs have two separate bolt hole sets. One set fits the 16 front and the other fits the 17 front.

Like I said before, the current brake set up on my hornet isn't stock.

I'll upload pictures tomorrow of the discs alone, on the 16" and the 17"...

The current picture is the discs on the 17" wheel...

Never seen a disc with that many holes in them before?
Maybe not OEM?
The problem with the 16>17 discs is that the bolt holes didn't line up.

Ah I see what you mean now. Erm you could get an engineering place to knock you out a spigot ring so the disc centre bore fits flush.

If you fit wheels to a car where the wheel has a bigger centre bore than the hub on the car, you can bolt the wheel up and it'll appear to be a perfectly solid fit. But when the car gets going above 40mph you get all manner of horrendous handling and vibration.

I fear there is a chance you may get some brake chatter, but can't say for certain

Yup, absolutely perfect.

From what I remember, people said my calipers and discs were sp1. I'll post pictures up later. Definitely not hornet brakes.

They could be VTR1000 (RC51/SP1) brakes, or they could be VTR1000 (F/Firestorm) brakes, I think they were a bit different.

I know that since you can swap the Firestorm wheels onto a Hornet, you may find they're from that if not an SP1.


I think Hornet and Firestorm both have 296mm discs but different callipers. SP1 has something like 320mm discs, but callipers may be the same on SP1 as on the Firestorm, they certainly look similar.

They are SP1. I remember now. At least the calipers are.

The original calipers that were on there were so fucked (pistons, seals, etc) and it worked out cheaper to buy a refurbed set from ebay rather than all the parts for it, which I did and was a direct replacement. Distinctly remember buying SP1 calipers.

Right, gonna go out now and get some proper pictures.

Well this is my second Hornet...

My first big bike was a Hornet too and it was a thing of beauty...

I still have it.... But it's in pieces!

Also, there is an easier way to change the 16" front... Guy on the hornet forum did say you can literally just use 17" wheel and discs. As long as they are Hornet ones. Use the same spacers and spindle. It's in the 599/600 "how it's done" section or whatever.

If you want uprated calipers however, then you need different forks/plates made up!

If you need any bits, let me know. I got plenty And I've done a lot of work on both of mine... So excited to get back on it!

Those discs are fine.

In fact they are made by ABE and are designed to be interchangeable between the two Honda types. The centre part not being a snug fit is also fine, they are designed that way.

If you have any doubts give Nick a call and he will confirm what I have said.
