I've just bought a pair of NC30 radiators (with hoses) for £146.40 final cost (delivered) from Winner Racing on Ebay. I fitted a replacement Chinese lower radiator to a friends bike a few years back and the fan holes were a mile off. This time around I'm much more satisfied. I had a little bit of fettling to do as the fan holes were not quite right but a little bit of work soon had the holes elongated so it would bolt up. The oem metal screen for the upper radiator had to be bolted on (the aluminum tabs were too thick for the standard self tapper fittings) and the tabs subsequently bent up so they didn't foul the cam cover bolts. The lower radiator was just hitting the oil filter so I spaced out the lower engine radiator mount a bit so I could still use the standard Honda brace bar. Oh, I also had to use a tie wrap on the tab for the wiring connector as the tab was too thick to go in the connector block. I didn't user the hoses as I already had Samco ones on the bike but the ones supplied look to be good quality

They even came much quicker than advertised so I am very satisfied!

Hope that helps,

Keith

Looks like the Chinese have made some improvements and you've managed to work round their errors. I suppose they're reasonably good value at £146, although I can't see why they can't get it spot on after all this time. It reminds me of a comment I read recently, which was directed at Russian build quality, 'they are a country of approximation'

I would be comparing the temperature delta and flow rate against OEM spec. Chinese radiators don't tend to perform as well as OEM.

May be but not about their missiles. They seems to be quite effective.

would be a great job.

Sound similar to the ones I just got.
Good shout on the bottom bracket, never thought of doing that.
They are also a little bit wobbly in the supplied rubber fixings.

As an update, fitted my exhaust headers and the fan cowl rests against one of the headers.
Tried moving the whole rad over on the top fixing but then the rad hose squashes against the fairing.
If only the fan fixings were spot on grrr.

The conclusion is jaanese work better than chinese. I cut away those horrible plates linkin upper andlower sides. I hae them fitted on my "slightly" modded vf400f.... I also have magtek front and rear. Front 3.5x17. On my facebook page you can ear it revving. The beast. search for Pietro Arrigoni
