Talk:Peter Williams (motorcyclist)

Racing Career box

I am pretty sure the statistics in this box are incorrect. Probably for someone who raced for MZ and was active for a few years after Peter stopped racing. Is anyone able to someone correct this. Cheers 86.133.63.159 (talk) 20:02, 14 March 2009 (UTC)

Monocoque

I seem to remember reading once that even Peter Williams acknowledged that his monocoque Norton was actually a "semi-monocoque". Any views, citations or sources? Arrivisto (talk) 19:30, 11 January 2015 (UTC)

Maybe, No, No in the same respective order as the questions above. Looking at the piccies, the only thing I could suggest that he and you were/are referring to is that the Norton has two shallow-section 'spars' with a relatively large space between, not a true box section as shown in the Ossa pic.
Norton
Ossa
Consequence of a tall four stroke engine. So little to compare with, though, no true comparisons. I'll have to look online to refresh my memory of the NR500 - I know I haven't got anything in the house (went the ebay way a few years back). Can't remember whether it was a complete circular enclosure, like a barrel laid on its side, or if there was an open bottom, or where the oil was!--Rocknrollmancer (talk) 03:08, 12 January 2015 (UTC)

Correction Maybe, Yes, Yes in the same respective order as the questions above.

"The unique semi-monococque construction gives the Norton the advantage of less weight, improved ground clearance and better banking angles than other, ordinary bikes."
Motor Cyclist Illustrated, September 1973, p.2 full page colour advert, From John Player Norton: The Norton Twins.

Found the above in the house when looking for other things...There is also what I remember as a prototype with a Trident engine called Bolide. I definitely no longer have these mags, but you can see it here and here. It helps knowing what to look for.--Rocknrollmancer (talk) 21:52, 18 January 2015 (UTC)

The other thing to mention before I put the mag away is that the same ad. confirms the letter-box slot in the fairing nose fed cool air direct to the carbs. Again looking at the same pic [23] it's possible the air was ducted directly through the twin side-spars, whilst the engine heat was ducted separately on to the back tyre!--Rocknrollmancer (talk) 12:56, 20 January 2015 (UTC)
