HPN R100 for sale 1977

HPN?.... but no bracing of the frame by the swingarm pivots?

Thought hpn always braced the frame around the swingarm pivots, and at the headstock (can’t see that area in the pictures showing).
Or is this a R100 in the style of hpn? Rather than an actual hpn build with a hpn number.

Looks okay to me tho’.
 
...not that i know that much about it but all the frames i've seen pics of had that extra bracing at the swinging arm pivot ... in fact we copied it...

I'd love to see what frame number is stamped into the downtube.....Look like it starts 6087....which is a 10/77 R100RS. I don't know what the HPN numbers are.
 
other than the extended swing arm, it does not look like too many actual modifications as opposed to bolting bits on?
 
I’ll stand to be corrected but I cannot see anything about the bike to suggest its got much to do with hpn

Thanks Mikey, that confirms what I thought when I saw the pictures. At least I’m not the only one that thinks the HPN bit is suspect.
It doesn’t look too bad in my opinion, but then again, I’m no expert on anything to do with airheads, but I believe mikey IS an expert, and I would go with his opinion rather that what is written in an advert.

Ride safe y’all

If it were a bike that had been produced by HPN,
Let’s say for instance it was built around the time the forks would date,mid 90s maybe,
It would have the characteristic frame bracing which this bike hasn’t got.
If was built when the bike was newer,late 70s,it wouldn’t have those forks.
Either way if hpn built it ,it wouldn’t have an under slung rear brake arm and rod etc etc
It looks to me like a pretty standard bike,with some early usd forks,
Extended swinging arm,
A modified st or g/s subframe and seat.
AKA
Shed built:D
 

When that bloke from the West mids who was inflating all the prices (unit 56) had this I contacted the guy who built the bike. He's a really nice bloke and though it funny when I said it was being advertised as an HPN bike that had been used in the Paris Dakar. It was a modified R100RS that he put together for the lands end trial and having a laugh on.


Keith Townsend built it in the first place.

Here's part of the email:-

"Hi Rob, I built the bike myself and no it is not a genuine HPN. I would be surprised if it has been ridden in the P/Dakar since I sold it."

Can someone knowledgeable inform the auction house, you would hope they wouldn't want to be involved in selling something that isn't what it say's it is ? Or am I being naive ?

Interesting how the rear brake arm is now low level. When it was first built the arm was out the way.

Possibly...
I was at Stafford one year when a roundcase Ducati 750 came up for auction. It appeared to be a Sport, a highly desirable machine, and was advertised as such. Various members of the owners club, with decades of accumulated knowledge and experience of the marque and model between them, were not convinced. There were number of clues - if you knew where to look - that strongly suggested it was in fact a tarted up GT. Legitmately dressing a GT as a Sport is not unheard of - the Sport is a more desirable machine - but given that it was being passed off as a Sport the auctioneers were discretely approached. It's quite possible that the seller was unaware of the origin of the machine (though s/he could have checked with the factory) but either way, the auctioneers were utterley uninterested...
 
As a buyer,it’s down to you,
Make sure you know what your buying,
£4/6k hmm ok
It’s also had an engine swap.
I’d be walking long before £4 k:thumb

Hammer price £5,520 .. I expect there’s Auction house fees + VAT to add to that.
 
Far too much.
I did send a message to the auction house asking for hpn build number and date.... never got a reply... strange that !.

I hope whoever is the new owner didn’t buy it believing it was a true HPN build..... and if they did, I can see the auction house being sued.
 
I phoned the auctioneers and asked about a Norton in the same auction, had a 500 bottom end but for sale as an all original 600. They did change it just before the auction to "engine has been replaced" but it went for much more than I'd have paid.
 
Way too much money for that,I wish I had bid on the R60/7 though im looking for one or a 75/7 for sensible money as a winter project
