Apology to Mr Honda.
Dear Mr Honda, I start by saying that I am very sorry for taking your wonderful VFR800 V4 motorcycle and tearing it to pieces. However I am also sorry that I cannot be sorry for how it went back together!
Mr Honda I love all your motorcycle machines. I’ve had several. They are superb to ride, very reliable, high performance and extremely well manufactured. I love the way your engineers have spent such care and time to lay out the engine components, the frame and suspension and most everything else in between in such a way thats assists greatly in gaining access for maintenance and much more so so easy.
And I especially love those great little things you do like how so many of your models share many of the same bearing sizes, bolt sizes, shaft lengths and designs. Wow Mr Honda, that was very special!
Sadly for you Mr Honda this last fact also means that much of your wonderfully crafted and machined high performance Japanese component inventory can be transferred between many of your motorcycle models with ease. And it is this that I wish to thank you for Mr Honda from the very bottom of my heart (and similarly from my bank account also).
(OK, sarcasm aside, my mum would not approve.)
I like very much what you did when you built this … it is marvelous.

But I really wanted it to be like this.
Like this
Like this
And like this
Why?
Hi, I’m Dave. Melbourne Australia is where I am and this site exists to demonstrate what happened when I let my Dreams transform into Goals leading to Plans and finally becoming Actions.
Let’s get started
The Honda VFR800 is a superb motorcycle with much to offer through many years of development, maturation and the earlier the years of racing success.
But it became a bit of a slug, become bloated, fat, heavy …. slow!!!
Coming from a long heritage, including superbike racing successes you would hardly know Honda VF and VFR.
It doesn’t sound like a motorcycle with V4 configuration engine should and with so much technology and definite potential built into this machine there exists plentiful opportunity to create something very enjoyable.
Then there were the looks
(they’re not bad, just not terribly sporting)
So …. I decided to change everything!
Taking this V4 powerplant with a solid chassis and leaving behind many Kilograms and un-needed excess was part of it.
To make a sporting machine from less so was certainly part of it
To build something from a clean slate without listening, even slightly, to the OEM specifications was most certainly part of it
And so it began …
I purchased the VFR from Fowles Auctions here in Melbourne back in mid 2006 (from memory) and it sat around in the shed for a good year or more while I put the parts list together from eBay through time. Also playing around with an auction damaged CBR1000RR at this time (that is another story).
From the auctions the bike would start, run (although strangely with one muffler closed over) and do most things it should. It wasn’t road registered.
First thing I did was to pull everything off in the way of plastic fairings and accessories, leaving a bare frame with a wheel at each end. It looked so much smaller and better in that minimal look and it stayed that way for some time, giving me many thoughts of what could be done.
When the part list was complete the process of repainting all the fairings plastics was taken on and from there it was a simple process of reassembly. It was surprisingly easy. I’ve restored a range of damaged bikes but the Honda has the most logical layout and design of all I’ve looked at. Great engineering.
Reassembly complete the bike went through the mandatory VIV (Vehicle Identity Verification) process here in Victoria at $440 per inspection. This is a recent requirement here to try to reduce the incidence of stolen bikes being rebirthed as parts. I’m not sure how effective this process is given nearly all the parts I purchased were from eBay and the VIV inspection service accepted the eBay receipts as per any other. It might just be a great way to give certain licensed inspectors $440 for a 5 minute bike lookover, but who knows …….
(BTW: a car VIV is the same price which does not seem fair to me but then again …….. )
Bike was registered on an early November Friday morning in readiness for a 2 day ‘mystery’ ride starting the following morning (gutted the mufflers that friday night
). Couldn’t cut it much tighter than that but all is well that ends well and the 2 day ride was a blast. The VFR ran perfectly, never put a foot wrong and was a pure pleasure.
The next year was simply transit from home to work for the VFR but eventually the desire to tear-it-down won out and it went into another bare chassis configuration in spring 2008. This was a fairly intense work period as a custom rear subframe was needed, custom front fairing bracket, fairing reshaping and fiberglassing, rear shock chang-over, painting … the list goes on.
Not sure exactly but I think around January it was in fibreglass CBR600 raceglass mode painted black and thus began some more aggressive and enjoyable track time. Summer of early 2009 put the VFR into near current road-going look and configuration…
That was until January 2010 when the CBR1000RR front end went in like a dream and now it finally feels like a true sportsbike that can now turn corners with confidence.
Now it is essentially a pure sportsbike with respect to chassis and handling but with the smooth tractable power that the V4 engine is renowned for. (and some exhaust noise)
The menu pages provide greater detail as to what has happened and will happen in future. (MUCH more descriptive detail and images to be added later)
Much more to do in the coming months (VTEC modification module, CBR954 swingarm, custom full exhaust, new rear end, new custom fairings, split fuel tank ….. etc) but that is it for now.
The deconstruct/reconstruct of the Honda VFR800 VTEC 6th generation has been and remains very rewarding to do.
Please feel free to say hi to me, ask questions and pass me comments

Background
After running a range of conventional sportsbikes (RGV, R6, CBR1000RR) I was fortunate to test ride a VFR750. Being very impressed with the rideability and tractability of the engine in particular I wondered why there were no such V4 configuration sportsbikes available on the market
That was 2006 and all that was available and went well were inline 4 cylinder machines
The VFR very much impressed me and I wondered what it would take to create a sporting version
After several damaged motorcycle auctions and letting the over-bidded rubbish go past I found a VTEC model VFR800 6th generation with little damage and at the right price. It was the perfect candidate as this particular bike had damage to the rear, not the front, and as such the forks, instrumentation, headlights, engine computer (ie: all the extra-expensive items) were undamaged!
Some time and after many repairs the VFR was restored to original condition. Painted gloss black (clear over matt black)

Hi Dave, got the link for this page from one of the VFR boards. Nice work on both the bike and the page. I think there are a lot of VFR fans who would have liked to see a more sport/race oriented V4 from Honda instead of the 1200 tourer that has appeared. In any case its great to see such good results acheived just by a bloke out in his shed with some imagination, tools and parts. Also it was a surprse to see your from Melbourne as well. Keep up the good work and maybe I will see you on the road, (especially if you ever go for a spin along the Black spur) Cheers Mark.
Fantastic rebuild,hey I couldnt agree with your introduction, I will be going hard to make my bike lighter and faster so seeing as I know jack shit about engineering, I will follow your lead,, first I need to change out the front end, you say cbr1000rr, fair dinkum please tell how that happens, what do I gotta do cheers Gary
Escellent job my friend, altough I suggest to feep the original pro arm swing arm, It`s a high quality and identity sign of modern VFRs.
@enrique cabrera
Hola Enrique, thank you for your feedback on the VFR swingarm. Yes the VFR single-sided swingarm certainly do have a unique and visually pleasing appearance. I might even paint mine black soon!
My interest in the CBR 929/954 swingarm conversion is from a weight saving perspective. All that single-sided swingarm rigidity sadly comes at a heavy price. I don’t yet have definitive weight differences between the VFR/CBR swingarms but reading on the internet suggests that the VFR swingarm maybe around twice the weight.
When I remove it from the bike I will then have a much better idea of the swingarm overall weight contribution to the total package and if it is worth pursuing from that angle.
But one of the fun reasons to try it is simply to try it out and see what happens.
Nothing ventured, nothing gained.
Cheers,
Dave.
@Gary Macintyre
Hi Gary and thanks for your feedback.
Luckily Honda front end choices are many and varied. Most of the late CBR models will fit, VTR1000 and others.
It comes down to headstock bearing sizes, tube lengths etc and how much you are prepared to modify the plastics, dash, etc to fit. The VFR forums have a number of examples of guys doing this too with other front ends. It is something you take on when you have already accepted that you WILL have to cut, reshape, remount, reroute things and that some of those changes will likely be permanent.
I chose the early CBR1000RR front end as I wanted something suitable for occasional track use and hey why not go for a pure sports front end, worth a try, they’re there
BTW: the 08 and onwards CBR1000RR front-end is not compatible without more extensive mods.
The difference for me, and making it easier, is that I wasn’t bound by any existing fairing shapes or mounts or objects that couldn’t be moved if things were in the way. In saying that I will probably move the radiators back a little soon as the lower triple clamp touches the radiator hoses reducing steering movement a little.
Are you up for these sorts of things with your bike?
Cheers,
Dave.
@mgvfr
Hi Mark,
yep in Melbourne too, not riding a lot as it’s been warm, although i did pick up a tray of 30 eggs from the Vic Market on the back of the VFR today, only broke 9 eggs on the way home!!!
I too was hoping to see Honda really pull something special out of the bag with the next generation VFR. I was thinking they might do something V4/V5 ish in a sportsbike considering the moto-gp examples over the last few years, I wish they had.
Thank you for your compliments, I very much appreciate the positive feedback for the work gone into it. I still have a lot to finish off and prettify but that for slightly cooler weather. It has been some work .. some beer as they say. The beer sometimes helps with the imagination .. sometimes.
A lot of it was helped by the availability of online parts referencing, tracking down what fits across multiple models, bearings giveaway great clues for that. If a shaft or a wheel or something from two different models uses the same bearings ……
Hope to see you out on the road Mark. I don’t go up the spur much these days (just got demerit points back) but hoping to be down at the superbikes in a few weeks.
Cheers,
Dave.
Hi Dave, Any update on this project ? I’m busy modifying a low mileage 5th Gen. The plan is to have a bit of a street sleeper. But one thing I’m concentrating on is reducing weight, to that end, I’m removing any surplus meat or compenents, so far I’ve saved about 12kg. The swingarm is a signature piece on these bikes, so I’d be interested in waht it weighs. Round two will commence later in the year & will include the backend.
Hi
I want to remove the PAIR system from my VFR800 since I read is heavy, lesspower and emit some noise at low speed.
Could you help me?
What can I remove (solenoids, etc)?
Best regards and very nice bike.
Jose Vives
Hi Dave,
Nice bike! Just wondering how much weight you’ve taken off it. I have a 5th gen that I’d like to shave some weight off (probably the easiest thing is to remove the centre stand), and I’m interested in knowing what worked for you.
There are rumours of Honda bringing out a RVF1000 in 2012 to be the new flagship sportbike, making the CBR1000 take second place in the Honda line-up. Dare I say it, it’s about time! Since the RVF disappeared, the Honda V4′s have basically been good general bikes, but nothing spectacular at anything.
Also wondering what you did with the brakes. I assume you de-linked them (as far as I’m aware, the linked front calipers wouldn’t fit on the CBR forks). I’d love to know how you went about doing the brakes.
Again, nice work on the bike. I hope to see you at one of the Thursday night group rides from the BP servo near the St Kilda marina (people meet there 7:00pm for 7:30pm start every Thurs night).
Cheers,
Danny
Hi Danny and thanks for saying hi.
Not sure exactly how much weight has gone from it but I’m guessing 20Kg+. Weight loss was really a sum of the parts. Things that were removed or swapped out for lighter items included – centre stand, forks, front wheel and discs (slight weight saving), removal of the entire DCBS especially the heavy front caliper, handlebars, fairings (yes they are heavy), pretty much every bit of non-required stuff and of course the super-heavy rear subframe and mufflers.
Will soon be putting a conventional swingarm (CBR600 or 954) which will take more Kilos off, especially considering the heavy weight of the VFR wheel also, if time (my wife) permits that is.
Also working on a different kind of motorcycle lifter to make working on it much easier. When that is done it will be easy to actually weigh the whole thing accurately.
The brakes – removed it all and ran a line inside the swingarm for the rear brake as shown here – rear-brake-line-re-route
Yep the front brakes are standard CBR1000 matching the forks and work great on the VFR.
Have heard of but never been on the thursday night rides. Might be a fun thing to do as have heard a bit about it from those who have.
Something you do often?
Cheers,
Dave.
Hi Chris, have been buying a few bits and pieces to play with further and looking for time to get in and do it.
Have CBR600RR & CBR954 swingarms to play with next. Will more likely go with the 600 swingarm to allow the rear exhaust headers to reach back under the engine. Looking to make a considerable weight saving there with both the much lighter swingarm and wheel. Will weigh the VFR swingarm when I get it out as it looks very solid and heavy.
Will keep you informed.
Cheers,
Dave.
Welcome Jose. I have done the PAIR valve removal. It is really only a minor thing to do and my reasons were to remove some rubber hoses and maybe get more of a nice rumble sound on deceleration. Not much weight in the PAIR system really, just hoses and space. Some people like it, some less so but again it is a very minor thing to change.
It is also a change made to other bikes with the PAIR system and not unique to VFR.
I suggest you take a look at the many posts on this topic – eg: &
Cheers,
Dave.
Hi again Dave,
Nice mod to the rear brake line!
Did you use the standard rear caliper? Can’t wait until you finish your page on delinking the brakes! I bet it would save a few kg, even without changing the heavy linked front caliper. Excellent stuff!
I haven’t been to the Thursday night ride for a few weeks… I’m waiting for parts to come in from overseas, so my suspension can be fixed. I’ll let you know when I’m back on two wheels, so maybe we can meet up at the ride, so I can drool at your bike…
Cheers,
Danny
