    Test ride report. RVF vs VFR

    1992 VFR400R NC30 vs 1996 RVF400 NC35


    Friday morning tootled over to cyclespot to drop the vfr off to have the speedo fixed, id already expressed a casual interest in the rvf they had, and cheekily asked to take it out, although with my history they let me have it for a few hours.

    Took it down the road coughing and spluttering, realised they had the fuel tap off, and then was suprised that there was no engine braking and it was idling at 3k... well the choke was on - which is unusual as my vfr choke doesnt hold a constant high rpm above idle... 10 buks of gas later, and after telling cyclespot 'I wont go far'....

    Performance. Got on the motorway and opened her up a bit, there is quite a delay in the throttle response - due to it having 30mm flatside carbs rather than the nc30's 32mm cvs - so they work of vacuum and you have to wait for them to work... It didnt seem to have the same punch in the midrange either. Took it round the harbour, sits on the motorway nicely, and is as joyous to ride as an nc30. Heading back down the motorway to cyclespot decided to really give it some herbs coming off the on ramp, flicking through the gears at about 13k it got up to 180 before slowly going off the clock, kind off disappointing as my nc30 seems to get to 200+ in under 10 seconds. More scrutinous testing in this area is required. Cant comment on economy as of yet.

    Gearing is suprisingly different, whearas an nc30 with stock gearing will hit 100kph in first, the rvf pretty much hits 100kph at red line in second - but with much shorter gearing you would expect much better pickup - this isnt the case. my nc30 dropped a tooth on the front and still has higher gearing than the rvf - but has way better pickup. But then like the nc30, the power range is so good that you dont need to flick through any gears and still have enough grunt.

    Riding position and bodywork. The riding position is more cramped than the nc30, im 6' 2'' but can still be quite comfortable - when you have your feet in normal position - ie. toe tucked underneath levers then your knees are too far forward on the tank, whearas if you push your feet back with toes on the pegs then knees fit snugly in the part of the tank that knees are meant to go. I swear the handle bars are higher too, which means less weight on the wrists. Seat is pretty much identical, and pillion seat is noticeably narrower. Insruments and controls are all nicely visible and accessable - except the top of the tacho - from about 10k through to redline - you have to be at full tuck to see it under the screen. A double bubble screen will remedy this. When i got back on the vfr it felt very noticelably bigger.

    Handling. There isnt a huge difference despite the rvf having a 17'' rear wheel rather than the nc30's 18''. The rvfs rear shock didnt bottom out like the nc30s as soon as i sat on it. Tyres were some bridgestone touring tyres, with hardly any lean angle, so didnt get to test that aspect. Id definately throw on a set of dunlop gpr100s or gpr70's. I read on wikipedia than whearas the nc30 will hold a line perfectly, the nc35 can change line mid corner - i decided to put it to the test, and it does it beautifully due to the usd front forks. Brakes felt really nice and solid too, the same as the vfr just they have had 30,000k's less wear on the disks..

    Looks. this is the reason i bought it, a bike as good as an nc30, but modern looking, immaculate, beautiful and not 15 years old.. The rear end is nicely reshaped, and the main change is the front end - foxeye headlights look trick, with air intakes either side, and the zxr-esque air ducts going into the tank look cool too.

    Worth twice as much as an nc30? simply no. Its not twice the bike. Engine performance the nc30 wins hands down, handling will no-doubt be the rvf once its got some good rubber, and the rvf looks sooo damn good I could eat it...

    Mmm, you're trying to get me to buy your VFR aren't you? There's some RVF forks on trademe, might get them with the money I save. That means you'd have good power and good handling right?

    RVF triple clamps won't fit into the nc30 frame... the later model nc30 forks have the same internals as the rvf anyway so shouldn't make much difference... a honda rs250 front end would be the trick... I see there is a set of rs triple clamps on trademe.. you'll need a spacer but they'll fit onto the nc30, and lighten the front up a lot... mine does wheelies of the throttle(has rvf engine/ shorter gearing)...

    Is the RVF frame that much different to the VFR? I thought it'd be a straight swap. Shows how little I know

    Looks like I'm still keen on the RVF. Shorter gearing sounds good for wheelies and town riding. Although that lag in power puts me off a bit. Can you boost the RVFs power up to VFR spec anyway? I've wanted to explore the idea of fuel injection, not so much cause I need more power but I'd be interested in tinkering around getting such a system to work. Then if that works, move onto a turbo

    HRC carb kits are still avaliable for the rvf, and stick a race pipe on it to free up the exhaust flow and some of that wonderful noise, should do the trick nicely for the road.
    We've thought about VFR800 fuel injection with a power commander on my race bike, but prob wouldn't be worth it. RLR racing in the uk, do ram-air airbox which gives a healthy 70odd hp..
    turbo would be bit tricky with the exhaust routing, supercharging would be easier, but you might need 20hp of the 60 the bike has to run the supercharger.. I wouldn't trust a VFR/RVF with more than 75hp anyway as internals start braking then... the cranks aren't the strongest..

    I remember seeing some site showing off their VFR with a 450cc conversion and it had titanium conrods and such. Although that'll all be big money so I'd have no hope

    TYGA sell both the HRC carb kit and they have their Moto Maggot 'silencer' and their full exhaust system. In the future when I'm earning more I'd possibly get them. Same with that ram air box

    Got to get the bike first... then get it on the road...

    These bikes are more than enough fun standard. For either id just recommend doing the exhaust.

    Oh hell yeah... 400's rock.. just put a load exhaust on to get that v4 sound outta em..

    G-force in america build those 450 engines, they've had custom pistons rods and cranks made... with special race gas they hp readings in the high 80's... faaaaark!!!!

    Ive always thought of the VRF/RVF is to be ultimate bike to own. Once of those bikes that if I could justify spending that coin on a 400cc of that age I would.

    Do they have alot more power than a CBR400rr? Ive seen pictures of the VFRs doing powerstands out of slow tight corners...mind you those bikes may have been modified.
    1990 GSXR 750 - want one, can be crap, can be awesome....pm me.

    Are those engines based on the VFR/RVF motors or are they completely different?

    True, just I can be power hungry at times

    That Micron exhaust on your VFR tempts me...

    Outta the factory they have the same HP.. but easier to get hp out of CBR than a vfr..
    CBR400RR NC29 is a fantastic bike, I used a standard one for my everyday bike, did thousands and thousands of km's on it and never let me down.. raced it too when i couldn't bothered getting my race bike ready.. more than holds it own in the twistys..

    They were VFR nc30 engines... they're still developing them.. next will be cams, fuel injection, ports.... don't wanna know how much that's gonna cost... so i didn't ask..
