twin disc front end

[mickthomas1]

Hi does anybody know what twin disc front end goes into a 1973 ntv 650. am i right in thinking they are 51 mm. cheers mick

1973 NTV?

I think the first NTV is from 1988, or am I missing something?

Btw, welcome to the forum Mick

Hi Mick,

welcome.

I have an 89 Revere and also thought 88 was the oldest.

Do you have any pics.

Worth a dig round as this has been done before.

I think Pivo is correct - the NTV600J was 1988
The NTV650J also appears to have been around in 1988 (I thought it was several years later than the first 600.

I can't recall precisely, but wonder if the stanchions are 48mm diameter? Perhaps someone could measure them for you. If not, I can but not for over one week as I'm not at home.
I've heard mention that a CBR600 will fit aNTy, but you will need to check this out for yourself.
I would say that it would be an awful lot of work and expense for potentially little gain.
You will need a pair of forks, pair of brake calipers, pair of brake lines and the means to divide the brake line and of course a new front wheel with two disks. Possibly a new brake master cylinder and perhaps new front wheel spindle. I'm taking a guess that the mudguard, wheel spindle and speedometer drive will still fit. All of this means a trip to the breakers yard, or superb luck with your eBay bidding.

Good luck whatever you plan to do, as always - grateful for your feedback to let us know how you got on.

Have seen various VFR bits appearing on NTVs, e.g. front forks / wheel / twin disc set up, even a fairing from the pre -1990 version (pre ProArm) which was fitted to a red NTV being sold on Ebay only this week (shame I just deleted the item earlier today as the auction's finished now).

Good luck. Post lots of pics please.

Easiest way is to swap the entire front end.
CBR600's from certain years are a straight swap, but I don't know what years.
VFRs are also a good source for bits, and it has been done to machine out the rear wheel to fit on the NTV (looks lovely, but it's a lot of precision work)

On the subject of NTV 600 / 650 being from 88. Yes, the 650 has been build since that year, but only on the continent.
See the history in the Honda NTV Wiki

Hi Pivo and Mick.

Welcome to the forum, if i haven't said it already... ;D

Have seen it explained and pics of it done elsewhere and it does look good, but it seems like a lot of work.

Not sure if the benefits would really be worth the effort.
Love the NTV but it is real workhorse, not some show boat racer.

Leave it as it is and just enjoy it for what it is, an absolutely stonking, workaholic of a bike

;D ;D

thanks everybody i put 1973 , what i should have put was 1993 thats what comes with old age the eyes arnt what they used to be . i have just changed the fork seals and they are leaking again i was going to get them recrhomed but i think they are too pitted as the new seals only lasted 300 miles. cheers mick

I'm having the same problem with eyesight, so no need to worry.

I cannot tell the difference between "Franklin" and "Buzzin" - they look so similar!!

If your fork stanchions are badly pitted, they will tear new fork seals up in a short time - but you would be able to see this.

I fitted new pattern seals on brand new stanchions in an earlier rebuild. They were weeping within 1,000 miles - I was very unhappy.

Original Manufacturer Parts are more expensive, but in this case, they would have saved me time (lots of it) and money (for new seals and new oil).

If your stanchions are badly pitted, rechroming is an option, but expensive. Wemoto can sell new stanchions at £95.43 each (plus P&P). They are good and reliable (and supplied mine).

If you consider the pitting to be manageable, I have heard news of a workable repair. I have not tried it personally, but consider it worth a go:

If necessary, remove and strip down the forks. Degrease the area you need to work on - do this thoroughly, Methylated Spirit evaporates leaving little or no residue.
Mix up some araldite and apply to the pitting.
When the araldite has hardened fully, polish it back carefully with a fine oil stone, or 1200 grade wet and dry (used wet). Use your fingernail to judge when you have achieved a smooth and level finish. Done carefully you should be able to fill the pitting and provide a nice smooth finish. The main thing to achieve is removing the sharp edges that catch on the seals and tear them.

For less than say £10 (to purchase wet and dry, tube(s) of araldite and some meths) it's got to be worth a try if you are patient and can spare the time.

I would add that while your fork seals are in good repair and your stanchions are not spoilt by pitting, it's got to be worth considering gaitors, or a compromise with some small fork protectors www.busters-accessories.co.uk/productInfo.aspx?catRef=MAP548234&kw=fork+protector (which do not require stripping the forks down)

Good luck and please post back with news of your progress
