Hi All. Hope you are all well.
For the last year, I have been restoring an LC2, or so i thought and believed. I had never took any notice of the numbers on the engine and frame, apart from the fact that they matched.
A friend originally bought the bike as a rough but running example a few years ago and it was dressed as an LC2 complete with screen etc. The bike was black without any decals. It had different forks and front mudguard but just thought these had been changed at some point in its life. I bought the bike off him 18 months ago and proceeded to restore it. I did leave the forks as they were and realized that the calipers were also different when the seal kit and pads I ordered didn’t fit. I still thought nothing of it and just continued as planned.
Fast forward to today, when for some reason I looked at the numbers which start 080 and realise that if the table I am looking at is correct, that this is a RD350 N1 ! Hopefully you guys will confirm this
It will then explain the black colour, front forks and calipers I believe.
Fingers crossed !

Yep 080 is a Uk n1. Hence the later front end and rear swingarm
There’s quite a lot of difference's including the loom,switchgear wiring,cdi, ignition,exhausts,clocks light brackets and the horn mounted under the tank Probably more I’ve forgotten 😵💫

Made my day !! Even though I now have to swap some things. I know I have the right forks, calipers, front mudguard. I also know the clocks & headlight brackets are incorrect but I have no idea if the switchgear or swing arm are correct or not and as for the horn mounted under the tank 🤔 Just a shame there are lots of parts like loom I have bought for the bike (LC2) but I guess they will all resell Is there anywhere I can find out whether it was black or white originally ?

If the switchgear connects under the tank there correct, the swingarm should be box section with internal adjusters As for original colour I’m not sure,maybe midlifecrisis will know Here’s an N1 I did that may help. rdlccrazy.proboards.com/thread/37587/black-n1-rebuildMatt

Highly likely if a UK bike it would be most likely white
Surprised at 31k-080 number though
I had an 86 on a D and it was 31k-078
If its actually 31k-008 then an LC2
An N should have side fairing brackets on the frame beside the little plastic infills

I thought all the UK ones were 077 and 078
Ones starting 085 were German 31w restricted models

It was this list i used which shows 080 as a European N1. It also had the forks and front mudguard on. Lots of parts were missing but have collected everything as an LC2 as thats what i believed it was IMG_0319 by Steve Jones, on Flickr

This is the bike currently. Not sure if you can tell if the swingarm is for an N1 IMG_0309 by Steve Jones, on Flickr

That's an early swingarm. Later arms had the chain adjusters inside the box section

Yeah someone already said it’s not the correct one 😁

That's an LC2 frame and swing arm
It has either complete later forks or just the lowers hence the different muddy and calipers
Another indicator will be the cdi. Lc2 is 29k50, n1 is 52y50

31k-080 does go with N model as per the vin list, I've just never seen one above 078
Frame has no fairing mounts as per LC2 and the belly pan mounts are Lc2
What reg letter is it on?

I'd also say that list of vins is the allocated range
It says the F goes up to 077000. You will never see one that high, they were mostly 053,054,055 etc

Also just looked on your build thread
The N and F used the same frame so as well as the side fairing brackets it had a headstock bracket and a different set of rad cover brackets
Your frame does not have any of the N/F brackets
Also the ignition steering lock tab is right at the top of the headstock like an LC2, the N/F was about an inch lower
N/F UK bikes also has the separate steering lock on the headstock like Euro bikes

Thanks again to all who helped

🤣🤣🤣🤣🤣
Easily done
Bike will be an 84 model so would originally have been the later white tank with red top and blue pinstripe like the F1
