What made me post was the RV4 quote... Not even close to the hallowed RV4 ! An RC36 full of innovation that would stand up to any scrutiny. How about a Slipper clutch??? That is what made the RC30 fast into corners and a real winner..i presume the RV4 also I find something new every time i look at the RV4 lol. Glad this RC30 is running a VFR750f engine that slips straight in. An rc30 with a 36 engine(woo) and a kwack front end(yuk) Not much thought on that oil cooler was there? Could he not go- water cooled oil cooler- a la RC30 for example? Its a bolt on with a Honda cooler on the oil filter connected to the water pump using the already present entry and exit point for the hoses. Just drill and tap... I would have that set up on my vfr, but a 2bros full system does not allow without further modification to downpipes. Would ask whats with the 'rear cylinder oil catch tank' rc30 hrc style on the rc36 engine? Handy to find out what use it might have on an rc36 engine Im sure Rick knows his stuff, so what going on there? Does he get more power to tame? e2a- More positively - What it does show to me, is how the vfr750f is nicely maturing - becoming more desirable and attainable to use again, especially for those special builds or spend thrifty rc30 owners. Can only promote good things for us collectors of potential scrap that can now be described as very useful 20 yr old VFR parts. I hope the older VFRs have at least another 20 years useful life in them yet.. they are so reliable and adaptable.... ill crawl back in me shed now...

Oh pants... skipped over the green van bits a little too fast. Didnt look very vfr like. Wonder if VFR was used and held on OK with all the mods.... Really interested in the cooler removal and small welded loop.. else might keep cooler yet.. will see... The 2bros system's pipes look in the way for a cooler on my oil filter connected HRC style to the water pump..

How has the bike been temperature wise after the loss of the oil cooler? Any idea on running temperatures now? Would like to loose my oil cooler, just going thru a few options first...

Wow an old thread reread.. lol Its been 3 years and a few racing seasons now on the VFR!! Yes it all works..very nice ty. The rear end turned out awesome, better than that heavy Harris example.

Nice see thru cover there..... Been thinking along the same lines for my 4th gen along with the SC44 slipper clutch am hoping to install around xmas this year. Am thinking of removing the face leaving a usable edge of clutch engine cover and replace with glass or what my local Alu. welder suggests. What material did Seb use for the glass? Was hoping to use composite materials/Araldite or what i find will work to stick the glass on and a yet undecided trim cover to give a clean finish to the outer ring surface. The clutch cover is not under lot of oil pressure so i don't see the need to weld any metal parts or use bolts? But i might be over simplifying things... will see... It is proven space age technology after all.... Was fortunate enough to be able to look over a Russian space ship last month which seals well in space using resin and fiber matting in the mix.... Russian earth landing module.. Simple computers being updated among other update work done here on isle of man. Hopeful relaunch after refit... Or i guess if Seb is thinking of selling a few i could well save myself a little work and buy a 4th gen version ready to roll?? Also had the oil cover from pro bolt as mentioned on thread in UK but for my 4th gen. Was no problem.. Honda fitment.. Have lock wired it on as it was a little loose fitting....

cool bike

Found the measurements. In my bookmark section... Taken from another website found to be very useful for reference, http://guukan.org/garage/swingarms.html Once again posted on VFRD.. Honda VFR ('90-'2003+), Hawk, RC30/45, NSR250 all use the same relative rear wheel offset. i.e. mix and match wheels amongst the various models and so long as the spindle face is unmolested the wheels will remain centered. 90-93 VFR (shock linkage mount is two lobes on bottom of swingarm)(shock end is a 'fork') Length: 565 Pivot width: 242 (+3.5 thrust collar) Pivot diameter: 20 Eccentric outside diameter: 105 Eccentric width: 70 (+3 crenelated 'edge') Caliper carrier diameter: 75 Caliper carrier width: 14 Brake rotor diameter: 255 Brake rotor mount diameter: 110 Sprocket mount diameter: 175 Wheel drive diameter: 100 94-97 VFR (shock linkage mount is one lobe on bottom of swingarm)(shock end is an 'eye') Length: 560 Pivot width: 227 (+3.5 thrust collar) Pivot diameter: 20 Eccentric outside diameter: 105 Eccentric width: 70 (+3 crenelated 'edge') Caliper carrier diameter: 75 Caliper carrier width: 14 Brake rotor diameter: 255 Brake rotor mount diameter: 110 Sprocket mount diameter: 175 Wheel drive diameter: 100 Hawk (shock is direct-mounted to top of swingarm)(shock end is an 'eye') Length: 545 Pivot width: 235 Pivot diameter (right): 15 Pivot diameter (left): <22 Eccentric outside diameter: 105 Eccentric width: 70 (+3 crenelated 'edge') Caliper carrier diameter: 75 Caliper carrier width: 14 Brake rotor diameter: 240 Brake rotor mount diameter: 100 Sprocket mount diameter: 165 Wheel drive diameter: 100 RC30 (shock linkage mount is two lobes on bottom of swingarm)(shock end is a 'fork') Length: 530 Pivot width: 235 Pivot diameter: 20 Eccentric outside diameter: 105 Eccentric width: 70 (+3 crenelated 'edge') Caliper carrier diameter: 76 Caliper carrier width: 13 Brake rotor diameter: 220 Brake rotor mount diameter: 110 Sprocket mount diameter: 140 Wheel drive diameter: 85 RC45 (shock linkage mount is two lobes on bottom of swingarm)(shock end is a 'fork') Length: 540 Pivot width: 250 Pivot diameter: 20 Eccentric outside diameter: 117 Eccentric width: 77 (+3 crenelated 'edge') Caliper carrier diameter: 76 Caliper carrier width: 13 Brake rotor diameter: 220 Brake rotor mount diameter: 110 Sprocket mount diameter: 140 Wheel drive diameter: 85 RVF400 (shock linkage mount is two lobes on bottom of swingarm)(shock end is a 'fork') Length: 540 (??) Pivot width: 215 Pivot diameter: 20 Eccentric outside diameter: 105 (??) Eccentric width: 60 (+3 crenelated 'edge') Caliper carrier diameter: 76 (??) Caliper carrier width: 15 Brake rotor diameter: 220 Brake rotor mount diameter: 110 Sprocket mount diameter: 140 Wheel drive diameter: 85 NSR250 / mc28 Wheel drive diameter: 85 MV Agusta F4 (shock linkage mount is bolt on, under swingarm. linkage arrangement is similar to Ducati 916) Length: 545 Pivot width: 255 Pivot diameter: 20 Eccentric outside diameter: 105 Eccentric width: 76 Wheel drive diamter: 85 Missing from this list are the VFR800 specs.... would be nice to add them if anyone has the time to do so... I have read elsewhere the 800 and 45 specs are similar, but cannot confirm 4 sure. :fing02:

yes the vfr750 eccentric parts are similar size to the rc30, then after the 750 was the 800, i believe the rc45 is the next best match to the 800 sizes...The measurements are all out there on the net. I thought i saved them on my lap top, but again they have become elusive. I have posted them on VFRD twice already so have a look if you get the time.. Not a lot of rc45 spares going around to my knowledge.....

You want to put an 18" rear wheel on your VFR ? Ask Jamon over at http://www.blackrhubarb.com/ what the dealio is with Ducati and RC30 wheel interchangeability. The selection of OEM Ducati wheels is much better, unless you already have an RC30 wheel. The RC30 did not have a cush drive, so yes it will probably be too short on the sprocket side to work with your VFR750 cush drive. RC30 spindle fits my 750 perfect altho here im also using rc30 hub. its actually 1 mm shorter than standard, which has no effect in situe. This mod was almost a straight swap.. No cush, direct drive is a much better responsive feel....The loss of rotating weight is very noticeable when under power! On the track the acceleration over other bikes puts most others to shame.... bring on the mods, you wont be disappointed... I guess i could have left the brake unit on the top of swingarm, but went underneath because i could...Had a brake stay welded onto bottom of swing arm, so it works similar to the ducati brake stay...I have seen BLS make up something also similar in his HRC swing arm, but his is proper posh... RC30 wheel 17 inch change using Dymag here, although Marvic and HRC also do similar mag wheels....here a 5.75 wide wheel... i think 6 gets a little too close for comfort to swing arm.. Bring it on...After a good 10 years of VFR dreaming, 250,000 VFR miles, its now well sorted!... Would love a new set of flash wheels,3.5" cbr929 front and 5.5 rc30 rear please, both 17"....but im skint as usual.....

Hey Guys, can someone send me a link to the original thread for the 929 shock mount mod? I have been trying to track it down. Just need to know how long the custom mount needs to be to make it work. shock install bits

Mine I've had since '04, it's a Shoei RF-1000 Miguel Duhamel replica, the black one. Rob's I'd have to ask him. He lives in your neck of the woods though, up in Lawrenceville. :fing02: The second is a KBC 'Gun duo' in red, Carbon Kevlar..... they have been out for about 2-3 years, selling for around £80 now, although i did get about £140 when first out.... I have been selling them in my shop for some time now.....

Cool.. you have pulled off the bit that i am still considering to move further with my build... Your exhaust that pulls from right to the under seat left. Will your join clean up like your nice shiny headers? Also like your welding to fit rear sub frame, i did the same but with billet. for the gap from the tank to the rear i now have Ducati 916 air box covers in carbon.. saves a lot of glassing up and with a little simple trimming they will look spot on! Post up more pick of how yours looks at the moment....would be nice for me to see how the exhaust looks in situe. I was going to run just one can under the seat on the right side, but my fabricator was scratching his head too much and talking money. Said i should just think about it a bit more for now...... :fing02: bike at the track over this past year such silly high res you can see the carbon weave... And below, the carbon air box cover(here still on the duke i got them off) to finish that hole under the VFR tank. Just needs a trim to fit the VFR. Carbon is excellent and very easy to work with. Also have the oil tray for underneath to add when i get five mins. I just dont have the joint similar to yours from the 2bros headers to the under seat end can i have stashed in the cupboard. Bring on the exhaust bending... Look forward to see yours done....

I ask for input from those lucky to run sp1/2 forks? What yokes are being used? Are they risen through the yokes a lot? i only ask as running 929/954 yokes with their relative off set means the 929/954 forks want dropping thru the yokes about 19mm to stop the VFR from running very wide on every bend. Therefore, longer sp1/2 forks will want dropping even more as they are longer running the 929/954 yokes to get a similar performance. The only advantages might include to add the handle bars on top of yokes comfortably rather than under, handy for keeping standard VFR bodywork and the SP1/2 are race bread items. :fing02: From practice, i have found the 45mm CBR 98/99 forks, running custom yokes with only a 3-5mm drop was spot on. The custom yokes i guess were CBR custom race replacements being the 45mm. The guy i got them from said they were made for the VFR, but as a one off i find that hard to believe. But as we know, Fireblade CBR parts being interchangeable its all neither here nor there. I simply reused my VFR steering stem pressed into them 45mm yokes. Most important here is the offset felt like it was similar to the standard VFR. Unlike the 929/954 and on CBR yokes with their gull wing shape and further offset. Handling was spot on with the 98/99 set up right from the off, unlike my 929/954 set up, which is still in need of minor tuning. CBR900 98/99 forks, race yokes, similar steering feel as standard VFR750 Above, No drop through yokes needed (maybe 3-5mm max) as i am sure there is no similar offset to the CBR929/954 gull wing yokes as below. CBR 929/954 forks with yokes. note 19mm fork drop needed to get bike round corners. Visually the shots here in comparison the 45mm items on top look as tho they might be further forward than the 929/954 yokes. I dont have them to hand anymore so cannot measure for sure. The gull wing design might also be deceiving? My ideal wish list would be 50mm custom yokes without the 929/954 yoke offset to run sp1/2 forks. Although these imaginary yokes might well make the newer blade forks too short to run comfortably..
