RVF is just pretty much a newer version of the VFR.

NC35 = RVF

RVF has USD forks, different (smaller & flatsided) carbs, air intake changes, engine internal changes, a 17inch front wheel, revised geometry and chassis.
Loads of other changes too numerous to list (and many of them too technical for me to understand the benefits of), it's not just a dressed up NC30.

So the RVF is a better bike than the VFR then?

Looks nicer and if you're racing you'd probably notice the changes. If you're not racing I doubt you would.

Extra tart value of USD forks though. The rear on the RVF is 17 inch down from 18 on the VFR so you have a greater selection of tyres.

What about NC23 and NC29's?


I thought it was just the rear wheel that was 17 inch, front on vfr and rvf has always been 17 hanst it?

Rvf has different carbs which apparently give more mid range.

I personally think it's an over priced, over rated, dressed up NC30, and the benefits of the changes certainly don't justify the cost difference imo.

The front has always been 17 inch yes.

The RVF also different shaped exhaust ports to help flow more gas and boost mid-range.

As mrgixxer says there are many small diffrences, but unless you're racing you may well not notice them.

Presumably your talking about the nc30 & 35 (as the other VFRs - nc21/24 are totally different).
As already said the biggest differences are, the RVF has usd forks (internals unchanged), 17" REAR wheel, styling based on the rc45 (as opposed to the rc30) hence the different tank and air intake/fake ram air etc, smaller carbs, different gearing, new frame spars (similar to rc45), the riding position is slightly different, and some changes to the engine internals.
IMO as to which is better is as much down to your own personal preference as anything as overall they are very similar bikes just the RVF is newer (and I wish I had another 1 Rolling Eyes ).

Ironically, the VFR is slightly lighter and more powerful than the RVF but the RVF is a much nicer looking bike, IMO.

VFR more poweful? hmm, I know officially that may be the case, but that's because Japan introduced a power cap at 55bhp at some point, so all bikes were listed as this even if they put out more.

It's only marginal but having seen loads dyno'ed it's pretty much across the board. Mind you, a shagged chain and binding brakes will take off more than the difference between them. So maybe all RVFs are worse maintained Mr. Green

My bad - i was perving at a bird at work who has lovely, massive (yet pert) tits but a horrible arse, hence getting the front and rear ends confused.

the cb400 superfour (non vtec) is the NC31 (vtec is NC39 iirc) the reason the engine is stamped NC23 is because the cb400 uses the engine from the nc23 cbr 400 with a few different engine internals like a heavier flywheel etc.

All cbr400 engines begin the code with nc23, even the 29's which are a completely different engine.
