Hi everyone, I have sat and read through as many threads about what forks will fit the nc30. I currently have a K model with the earlier rubbish forks so want to go USD. Now I know it's a waste of money Etc etc but I have a few questions-

What years zx636 and zx6r forks fit the zxr400L yokes?

Can you always use the original discs and calipers?

Do you need the zx front spindle?

Or what year cbr600rr forks fit and what do I need?

Will be buying rick Oliver's conversion kit but don't want to splash the cash on something that won't fit. And if anyone else has any other suggestion that will fit fire away

Thanks

Triumph 675R forks fit with RVF400 yokes.

Do a search on here, there's a thread on it somewhere.

I believe the 675R Ohlins forks have a slightly larger diameter at the lower yoke. The regular 675 forks are supposed to slide right in apparently.

Its me who started the 675 fork conversions, I run daytona 675 forks on my race bike, need daytona or street triple 675 forks, rvf yokes, honda wheel + discs, triumph wheel spindle, 675 forks are 50mm top/53mm bottom like rvf but 675r ohlins forks are 53mm lower
I have a pair of these on their way to me :-)
I will very very soon be able to supply yokes to suit 52mm or 53mm forks + the correct wheel spacers for the conversion

Im going to do a proper 'how to' and see if it can be made a sticky thread so everyone can find it
Any other questions just ask

Great thanks for replies as I know there are some conversions more common then others but I like the sound of the 675 conversion. Great information regarding what I need thanks a lot. I take it the triumph wheel spindle fits directly through the vfr wheel then? And I guess you need the triumph brake set up apart from the honda Discs?

Thanks

Ill sit down + do a proper write up tonight for everyone

You dont have yo use the triumph calipers, they are 108mm bolt spacing so lots of calipers fit
I use 2004/06 yamaha r1/r6 calipers, they look nice + they are 1 piece, sort of like a budget monoblock, regardless there is a very very minor setback do to ideally needing 300mm discs as there is a slight overhang of the pads with the honda 296 discs, ill put all the info in the write up though, can either go bigger discs or have 2mm skimmed off the caliper mounting face

Another front end that is nearly a direct fit with RVF yokes is the 05-06 600RR. Fork spacing is identical, so the wheel, axle, spacers, brakes, etc. all fit without issue. The only difference is that the upper fork tube where it slides into the top yoke is 2mm too small. A 1mm thick piece of shim stock should sort it, but a proper upper yoke would be even better!

Actually, I'm almost %100 sure the bottom triple for the 675R forks is 54mm,, same as a CBR1000.

I have ZXR400L forks on my NC30.
I had to make an adaptor to lift the top steering-head bearing by around 30mm, to suit the ZXR stem.
I also had to make adaptor plates to mount the NC calipers to the forks.

Speaking from experience, the cost does not warrant the upgrade. When I converted my 30 to 35 front it ended up costing the guts of about £500. For £500 I'd rather put newer stock forks in with uprated internals, better calipers with decent pads and master cylinder, a full service kit, new plugs and a proper dyno set-up. Each to their own I suppose.
