An introduction to a double build of the Tamiya VFR 750 RC30.  I'm intending to build 2 race bikes from the early 90's

 

BOTH.jpg.47629ff85c3eb8fdd860d77b121716c9.jpg

 

The first is an RC30 from the first ever year of WSBK in 1990, the violet and black Team Rumi bike.  The other build is the 1993 Castrol Honda Britain ridden by Nick Jefferies winning the TT F1 race in that year. Both very different bikes requiring much alterations to the Tamiya kit, but I will start with the Team Rumi bike.

 

The Honda VFR750 was a pure racing motorcycle for the road and to my eyes one of THE best looking bikes to ever come out of Japan.  Yes It did have flaws, but the brief ride I had on an endurance RC30 in the 90's left me speechless!  Although a 750cc it was small enough and light enough to feel like a 250cc when riding and I did always yearn for my own RC30.

 

Build1: Team Rumi

realising the then newly homoligated  Honda RC30  the perfect choice for an attack on the new world race series of World Superbike, taking over from the old F1 series.  Always beautifully turned out the team would take the first ever championship  with backing from Honda and factory engines allowing US rider Fred Merkel to win the championship.  However, as usual I intend to model the No2 rider for team Rumi,   the Italian Superbike champion Baldassarre Monti

Tragically killed in a road traffic accident in 2008 he was an exciting rider and always a fast starter. This one is for Sarre'

I already had a part started RC30 in the stash so got another on order along with the new Hobby Design detail set on back order with Hiroboy.

One of the first alterations made to fill the headlight opening in the fairings.

Then primed the bodywork

Still waiting for detail sets from Hiroboy so got as far as I can with the frame and mounted in the jig.

The HRC works engine has many differences from standard and I have remade the clutch cover from stock;-

More to follow..

The Rumi RC30 also ran with 3 spoke Marvic rims which I'm using a donor Ducati 916  to use for the wheels:-

Found a good colour match to the Rumi violet from Zero:-

On the bench right now I'm working on a new turned shock reservoir, 027.jpg.bf26d22c023f819a796bd5289ed982d6.jpg

Great start Doc! I love this bike and I'm excited to see you progress in this build!

 

Thx MW, seem to be taking some time to get going but once the engine is in and I can start plumbing it should look like I'm making progress.

Wow! I cant believe I missed this thread!

 

I totally agree that this was one of the best looking bikes ever built. I'm sure they sell for crazy money  these days right?

 

The work you done on the frame looks fantastic, I think you captured the metal look perfectly.

 

I look forward to more updates Doc!

Thx Imster,

 

Yes it would have been a good investment in the 80's, recently saw one on ebay for £40k...........O.o  Might have to wait for that winning lottery ticket!

Thx Rob, glad you like it.

 

Had a delivery from Hiroboy yesterday of the brand new Hobby Design detail sets for the RC30.

 

028.jpg.39356836c367ecb316d46dc4b9f23eac.jpg

 

Much of the kit is obviously for the road bike but many of the parts can be used, so made a start with the chain building.

 

029.jpg.cc584db812d89f7f61b6b502f9ce461a.jpg

 

Never tried a 'rigid' PE chain before only having dipped my toe with a Top Studio version which I found incredibly difficult to assemble.  This seems to be going together pretty quickly and although the Rumi race bike never ran with a gold link chain I can live with the bling!

 

More soon

OK so an evenings work has the engine in and chain installed:-

 

030.jpg.62265c14c9f67454f05b6cfd1ffbcbb5.jpg

 

031.jpg.bf938e28453799795935e9ab7b1f9bbc.jpg

 

034.jpg.be95283e7951f173119eb2a651dc7483.jpg

 

 

Plenty of chain link spares in the detail kit just in case but the carpet monster only accepted 2 parts from my tweezers! Next up I'm casting new brake calipers as the kit only has one side modelled, both front and rear.  I'm using the existing ones as a master and simply casting another for the inner surface.  Plug caps have been drilled out to accept the blue HT wires and will have to scratch the coils.

 

More soon

Thx guys,

 

Andrew, as the Hobby Design is a rigid PE chain I used simple cyano gel to assemble the chain parts.  I did contemplate using PVA as I had with the Top Studio chain but as this is fixed there seemed little point and the cyano gives a much stronger bond. I will be weathering with oils eventually which should tone everything down a little.

A trip to the SMW show tomorrow to replenish supplies, my superglue is well past is 'use by' date!

 

Should have some more progress pics soon.

 

Cheers

Wow, I completely missed this thread.  Nice work so far on it. Those chains are fiddly, but make a big difference on the final model.

Thx Dallas, slow progress this week.

 

I have both front and rear calipers cast in resin using the originals as a master and simply pressing them into white putty for the mold.

 

035.jpg.b442a919c8862db71559cdf7b7279d30.jpg

 

Acceptable for the inside face of the brake caliper.

 

Then concentrating on getting the rear end completed before I move forward. Added the PE rear disc running it in a dremel to achieve the wear on the face, along with connecting the shock reservoir and a little plumbing.

036.jpg.5144cd51b20240a69d9b22c0aa8eb356.jpg

 

Need to add a catch tank on the top of the rear subframe and get the rear wheel in.  But first need to check spacing as I'm using the Ducati 916 rear wheel I'm sure the alignment will need some adjusting to get the wheel to sit true.

 

More soon

Cheers 44 B|

 

A little more progress worth showing.  I had to sand off the tread on the tyres so mounted into the lathe and ran a coarse file along with various sanding sticks on the surface.

 

038.jpg.2c0f768bb4b418ec1e2c20a6c5934be2.jpg

 

Then added the 'race worn' tyre to the 916 rim, painted in Zero gloss white.

 

039.jpg.8f196d5cbb5748c3664acd98727bde4b.jpg

 

The centre fixing screw replaced with hollow tube which is drilled and a split pin added.

 

040.jpg.32b0bff2d43e7321477e6ae7f2d16a21.jpg

 

Now working on the rear catch tank to be added to the subframe before the radiator and oil cooler get some work.

 

More soon

Very clever! I use my lathe for this too... Very clean work on that wheel too!

Is this bike one I'd need to make a special rear axle for? Just wondering...
