Royal Enfield Model D
« on: January 13, 2018, 02:20:14 AM »
Hi All,
First post from Dunedin New Zealand. I have a Model D that I purchased from a farmer for $15 ( 7 Pounds) about 40 years ago when I was 20 years old. Just starting the restore process, good things take time.
Motor has Serial number D4044 and gearbox has HJP - 2 and ENF-39. The bike has telescopic forks which from my readings would make it around 1947-8 when they were introduced by RE.  As it was sent to New Zealand I wondered if it was a bitza built by RE to get overseas funds post WW2. It is missing the clutch cover tin work, had a home made exterior cover. Was running when purchased.

I would like to know age if possible as the tele forks seem a bit odd, frame does not appear to have been modified.

Regards to all,
Neville

Welcome aboard !
Any chance of a pic of the whole bike - help prevents making an absolute howler from misunderstandings.

You may have seen the very recent discussion here about the 1951 Model S exported as part of a batch to Australia, and unknown to the historians. So yes, such things are possible.
Having Graham run those numbers through the RE dispatch records will likely shed some light on this too.

Is the clutch cover tinwork the same as for your G or J.?
A lot of military bikes came out to this neck of the woods, so such parts are not impossible to source. Have fun.

Hi,
Managed to get frame number Z0102?337, bit hard to read middle number has been damaged. Frame has very light plates welded at headstock. Photo's of frame and motor attached. Pic of my T100s 1970, I'm second owner purchased in 1973, always been road ready and I have done over 60,000miles on her.

Those forks look remarkably BSAish to me. I'd swear I have an identical set from a C10-11 in my workshop which I intended to put on a Francis-Barnett. Unfortunately ancient bones and creaky joints are winning the battle. No Fanny-Bee battling iron for me.
Personally, as they are an excellent fork and came with the bike I'd keep them on. They will give a much better ride and navigation than any girder fork and are typical of what was done back in the day to keep a bike on the road. 
I'd retain the headstock bracing as well. The Poms tended to skimp on building some frames in the 1930's due to oddball taxation rules favouring bikes under a certain weight. They weren't really  sturdy enough for our roads although the easier hydraulic action of those forks will help a lot.
Best of luck,

Many thanks for the update on the forks, so it will be a bitsa. Based on the New Zealand Kiwi "fix anything" attitude the forks most likely modified after it arrived in NZ. I am interested in finding out what year the bike was sent to NZ and if the frame is for a model D.
There is a small oil tank between motor and gearbox, looks home made to me, has a block of wood as a space filler.
Regards
Neville

Hi All
Just to throw  a further spanner in the works  ::)
I wonder if the frame number is Z C10 which would make that BSA as well
The front half of the frame has BSA features not to mind the forks fitting so nicely ???

Hi John
Yes it would make sense that frame is BSA as well, I will have a close look at motor mounts to confirm these have been added to fit the RE motor. Thanks for your knowledge

Hi John,
After a look at BSA frame numbers on the mighty web I have found that frame is BSA C10 or C11 from 1951.

Cheers
Neville

Hi Neville,
Hmm??? Ok the front half is BSA but next question is what is the rear half?
The BSA rear frame did not extend along under the engine and gearbox
The joint where the front and rear halves of the BSA frame meet that also takes the centre stand pivot
is a high wear point and causes a "hinge in the middle"  >:(

Assuming they haven't just been added/welded there, the tabs for the lower back mudguard mounts look like they could be Enfield, and several of the other tabs and brackets also look like they could be Enfield items. Enfield seat brackets onto the frame are quite distinctive - a closeup of one of them could be quite instructive.

So perhaps, with some investigation, the back half / lower frame could be Enfield (?).
They do bolt on in two separate halves.
It also looks like it has the lower tabs - and was made - for a rear stand.

Am I allowed to ask what gearbox was fitted? BSA first fitted a three speed to that model and then upgraded to a much nicer four speed. Or does it have a four speed Albion?
