I've searched but didn't find out what I needed to know.
How can this setup be achieved on an NC30?
Anyone use it?
Pictures?

I've seen instructions, some years ago mind, you need some of the RC30 bits to do it but it can be done.

It's years ago that I found it on the web too.
Can't seem to locate it now.
I'd imagine it would be a nice mod for the track.
As for finding the RC30 parts.....it might be easier to fabricate one from hens teeth and rocking horse s**t.

ISTR it was only a few items you needed which should still be available from Honda[1], I've had a google myself but no joy.

[1] Seeing as new parts for my '88/89 VFR are still available.

Why bother, the NC30/35 and RC R45 do not use it, and a lot of race rc30s take it off.
I have ridden RC30s with and without, and did not find a difference.

Dave. Only fix that is needed to be mended.

I reckon it would have been part of the race kit (which it wasn't) if it was worth having on the bike.

Good point.

Also if you look on modern bikes nearly all don't have one. You would have expected for example Moto-GP to have them if it made a difference and they don't.

I would take slight issue with Dave - having ridden RCs & NCs with & without I think the linkage gives somewhat better feel and rear wheel grip under braking on bumpy roads.

Of course any bike on which the rear brake torque arm is articulated and attached to the main frame rather than the swingarm achieves the same isolation of braking forces from suspension action as that RC30 arrangement and by varying the relative positions of the swingarm pivot and the front anchor point can be made either pro- or anti-squat. However, a quick online rummage for photos would seem to suggest that most (all?) MotoGP bikes have their rear brake calipers anchored direct to the swingarm and a walk round our showroom has failed to turn up a single new or recent used bike with any other arrangement...
