Title: Yamaha RD400. The Model Guide
Post by: SupeRDel on December 26, 2005, 03:18:19 AM
The Basic Yamaha RD400 Model Guide



This is a list of the models thru the 400cc range to the best of my knowledge. This list is UK based. Overseas models details may vary.YAMAHA RD400C. The first of the 400"s that was first introduced in 1976. The first ones had wire wheels with the mags as a ?30 optional extra. Nearly all were sold with the mag wheels. (example - see below)









YAMAHA RD400D or DX. This model ran from 1977 into 1978. The C and D models were using points ignitions. Both had footrests bolted under the frame like the early 70"s RD350"s. The D model now has a seat tail cover. Wheels were plain alloy coloured like the C or black painted.









YAMAHA RD400E Probably the most remembered and sought after is the E in white with red graphics. The Zeros on the side panels are filled in black. The points are now gone to be replaced with CDI. The footrests are now mounted on the sides of the frame. Thinner spokes on cast wheels, 35mm forks, revised porting giving 44hp on the 400, single piston floating alloy brake calipers, larger bore exhausts.  Note. If you intend to fit expansion chambers then be careful when buying as the rear mount positions have moved from the C and D models.













YAMAHA RD400F 1979. Just a few minor changes, dog leg handle bar lever. Side panel graphics MAY differ slightly from the E. The back ground behind the zero"s are hollow (not filled in black). Both the E"s and the F"s came in white which causes great confusion. The true test is to check the frame/engine numbers (see below)

 











----------------------------------------------------------------

Below are the model that were available in the USA, Canada and Oceana regions.The 1976 RD400C. Early RD400"s came with wire wheels. The alloy wheel was an optional extra costing more. This one is mine in the condition I found it. Looks a lot better now.









This is the picture from a USA brochure of the bike with alloy wheels. All C models had alloys that were in natural plain grey. This early photo also shows the bike with a solid full length exhaust. Pretty sure only a few, if any, ever made it to the road like that. All 400"s have a rubber exhaust joint - 400"s never had a castle nut downpipe join. If you see a bike for sale with castle nut exhausts - they are off a RD250.  









This is the RD400D from 1977. In some countries they came with slimmer fuel tanks holding 13litres. The fatter tanks hold 16.5 litres. There is No seat cowl either unlike the UK "D"









This is the 1978 RD400E. Same graphics as the D but in different colours. Unlike the UK "E" the frame is still the same as the C/D with underslung footrests and a straight kick start. The seat has now got a rear cowl as well.









The Yamaha RD400 Daytona. Probably the ultimate in the 400 range. The heads are joined with a Ram air type cowl.

Wot you see above is just a basic guide there are many variations around the world. I will try to add more of the model colours and numbers when I can. If you have any information and details to add then please do so below and I will see wot I can do to add to the listing. If you are new and have a question then please ask via the "tech section" or try the forum "search". Many questions repeat so your answer may already be there. If not or No luck then please ask

just like to say my 250E had was red n white with black wheels and the zeros were filled in black when it was new ,1978 model without dog leg levers. the slightly later F had the red wheels dog legs and the zeros were not filled in black + the cdi has bullit connectors not a block connector. As i had one of those too silly things i know but people do ask, ps im not having a go and keep up the good work dude.

The zero info came from Glen Oliver our graphic expert and reproducer.
I am not surprised to find that things were miss-matched.
Yamaha did some confusing things

No worries at all mate. I"m not saying my guide is spot on. Its just a general guide, you will never stick them down exactly to every minor detail.I agree the 400E either had red or black wheels, and straight leversthe400F had the dog leg levers, probably red or black wheels as well.The filled in zero"s were mainly fitted to the E, I would not be surprised if some F"s had them as models changed.

Post by: writebike on February 12, 2007, 09:20:59 AM
just to add a few facts here;

the RD400 originally arrived in the US and australia with a solidly mounted engine hence the un-jointed pipes
this was going to be the production model until the bike was tested in europe and slated for its heavy vibration caused by the longer stroke
this then led to a series of stop gap measures to help this including
a rear rubber mount for the pipes and indeed the jointed type seen on the 250 before eventually settling on the engine mounts and rubber joints as seen on the final 400 model

there were some UK machines around during the early days with variations of either of the above although i know one for certain that had later pipes fitted in 1977
and around 150-200 RD400 "C" models with the solid pipes as pictured above

I have an RD 400. Must be 1980 canadian model, but I am not aware of that.



Its number (coincident chassis and motor) is 3M4001470. It runs on CDI, not points.

I have seen a list of Yamahas" motor numbers that classified it as an RD400G.

I do not know why the number does not coincide with that quoted by the canadian guy, perhaps my bike is a model for Japan.



It was first ridden here (South America) in 1981, but I am quite sure it is a 1980 model.

I also have an RD400 here in Australia that appears to be a Daytona Special with a 5/79 stamped on the compliance plate eng/frame 3M4-000599 according to the chart on speedandsportinc it is a 1980 RD400G not F I have the original rego papers stating it was 1st regestered october 1979. Mine has not been regestered since 1983 and has 6760km on the clock. I went for a short ride around the block on the weekend 1st time the bike has been ridden in 25years and with fresh fuel stars 1st kick and performs beyond my expectations.

Am I right in thinking that the RD400G was replaced with the RD350LC in Canada much earlier than in the US?

Also did Canada get the LC at the same time as europe?
Title: Yamaha RD400. The Model Guide
Post by: YamaHead on October 29, 2008, 05:23:24 PM
The last 400 we saw here was the Daytona Special 400F in "79.

I believe the LC was offered in Canada starting in "81....

But we didn"t see anything else RD related, till "84-"85 with the RZ350.



We"ve always ended up getting the short end of the stick!

Hi Chippy, do you have a manual for the rd 400 G (with CDI and no points)? I have the wiring diagram for the rd400 , I suppose it will go for the G model, but I do not know if all measures, particularly BTDC, will be the same as those of the "C" model (the only manual I could obtain from the web). I have also bought a Haynes Manual, but it does not seem to cover my model.
Title: Yamaha RD400. The Model Guide
Post by: bazerque on November 20, 2008, 06:48:04 PM
I have seen on ebay some years ago an appendix to the factory manual that had a reference to the RD400G.



This model seems to have been sold in Australia, Asia and South America. I do not know whether changes between this RD400G and the E model are only cosmetic or if they involve other changes. My G model has CDI and the "RAMAIR" double head.



If anyone knows about the manual (appendix) for this model I would be grateful if he/she can tell me how to obtain it.

The RD350LC came to Canada in 1981 in White with blue graphics, they seem to be impossible to find in any kind of stock condition, they are all beat or tired beyond belief. In 1982 I think if my memory serves me correct they where black with red graphics, never seen one used all these years later, either did not sell well or all of them were beat on and destroyed.

I think they all became Rz"s in 1983?

Post by: SupeRDel on January 18, 2009, 10:46:24 AM
Its always possible that it was a old stock C model that got registered late.



In 1975, I bought an old stock RD250A brand new for ?450 at the time the RD250B was the new model - it cost a lot more as well.

My father owned a Rd400 for more than 20 years, we are restoring it and confused about the engine serial number. The engine serial number is only 1A1 unlike the other rd400"s which has several numbers following the 1A1. Can you guys help us unravel this mystery that"s made us think for so many years.



Engine Serial Number: 1A1   (only)

What model is this specific rd400 built?

Could the engine be possibly the early model produced or the first one manufactured?

Frame Number: 1A1200489

Japanese imports  have the prefix only on the engine.

so could have been a import or replacment engine.

It came directly from japan when we bought it in 1981, it came with spoke wheels and a different decal from the original models. thanks!

Well, I carefully read all post but still disoriented. Couple of years ago I found this beauty on a garage. I?m positive it?s one of the latest RD400 but I really can?t descipher if it?s an F or a G (no decals at all). Engine and frame number is "RD40082000196". Spoke wheels, tank shape and side covers look like an F or G. Cylinder heads an exhausts say "2R9". Any suggestions?



PD: Somebody told me it?s a 1982 "overseas" model, probably built with parts from an F and a G. Despite it runs (race?) very well with all systems working properly I will start restoration after your advice.



Thanks a lot.

Well its a 1979/80 RD 400 F or G, either the Canadian or Australasia version. As you said its a 2R9 motor and ppipes fitted to the Daytona Frame, dont worry Yamaha made em like that



Normally the frame No would start 3J7 for canada or 3M4 for australasia. Having the RD400 prefix on it may mean its a japanese market model.



the bike has been modified, indicators seat, front mudguard, the pipes look like the header and muffler have been welded together....but hey I bet thats a rare beastie in ecuador!
Title: Yamaha RD400. The Model Guide
Post by: Agustín Bruno on July 31, 2011, 03:42:15 PM
Thank you very much. I already found the original seat and front fender so I?ll set them up asap (looks weird tough) also chainguard not seen at photo. I think everything else is factory.



What should I do about decals? Daytona F or just G?



Thanks again.





PD: G ones usually got CDI right? Well, this one is points...

PD2: Exhausts are not welded (luck), just dirty.

Not as far as I know. I know there is a couple of importers tring to sell them.



My red one is the only C that I know of in the UK. There is a few later D bikes though.



I did once speak to a chap who"s 400 was an import identicle to mine. He then converted it to a white UK bike. Took a rare bike and made it common.

Andy,



Do you still have the 400 as I have one with the frame number only 2 digits different to yours but it is a white tank with red decals and the side panels have the 00"s filled in black.



I am only the 3rd owner and my mate who I bought it from would not have changed the tank and side panels and the person who owned it before that (bought it from new) only had it for a couple of years so I doubt they would have either.



Frame number suggests a "C"model but colour scheme suggests otherwise. It has points as well which means it is from earlier.



What"s your gut feeling about this one.

I have just bought what I thought was a RD400C model (US import) Frame Number: *1A1-310831* ??? It still has the headstock sticker saying it was manufactured in Jan 1977 and it has the black shocks and the later idiot lights cluster so I believe this now to be a US "D" model as per the earlier brochure photo in this thread!?

Here is what it looked like when I got it which was very original down to every last nut and bolt:-

Alright chaps, I've just bought sight unseen a coffin tank on Eville Baye for the princely sum of five hundred Australian bucks. Don't get excited, its a boat anchor. Engine and frame numbers are close but not matching, musta been on the same assembly line though: Frame 1A1 110276, engine 1A1 110252, allegedly, I haven't "met" the bike yet, its still with the freight company.
Does this theoretically make it an "E" ??

Hi all please forgive reviving this thread but I'm struggling to find out exactly which year and colour my RD400 is/should be and wondered if anyone could help with any degree of confidence?

Firstly it's got lots of none standard parts so they don't help but:
The Frame no is 1A30330747,
and engine no is 1A3330747.
reg is DMF 144V.
Reg doc says 'date of first registration in the UK 24 08 1979 and it's the same as the date of first registration. But next to colour it says NOT STATED.
Yamaha UK reckon it's probably a 78 model but can't say for sure, but model info here suggests a 79.
DVLA can't tell me anything untill I fill in a V888 and send 'em a fiva.
At the moment it's black with red decals although obviously painted as it's metallic.
Any ideas anyone?

the extra 0 after 1a3 is just what some dealers registered bikes with back in the day
it will not be on the frame so you have a matching nos bike

UK bike as far as I can tell, date of first uk registration is the same as date of first registration. I guess that means UK bike? But according to frame number listed on page one of this thread ....79??
 Plus it seems the engine and frame numbers match as you say GAZZAT2.

Yeah, Yamaha weren't very convincing or even confident. I'm waiting for the DVLA to come back with some info on the colour but was wondering, was the Low Gloss Black colour available in the UK? It always seems to be mentioned with the word 'Daytona', so I'm wondering if it was a US only colour option?

I recall the 250E being in a turquoise green/blue colour. Never saw this colour on a 400 though.

According to the colour chart on page 1 of this thread, Low Gloss Black was a '79 F colour option, and Marine Blue '78 E.  I have seen blue 400E's, in fact got outbid on one for sale when I was looking for mine!

Might sound daft but could you specify the colour of the decals back in 79? Mines Black with red decals.

My latest project bike is matching numbers 1A3-3001## so I am assuming it is an E model given that F models start from 1A3-33####

If someone could confirm this it would be appreciated.
