Bonhams Lot #158

Both are Norton history, the Manx has all the wins, the Challenger shows how not to do it, overweight and too slow. Both would be in my Garage if I win the lottery before the 15th ;)
 
Well, today's the day, Mr Sparks. Any predictions on the final price before the sale - I'll say 34,200 GBP

Anyone seen this up close? Wondering if the rear sprocket is inside or outside the swingarm?
 
The sprocket and disc are outboard of the swingarm - this has been discussed here someplace before.
Oddly, the chain goes behind/inboard of the shock there. Must be a narrow swingarm.
Very narrow pivots for the swingarm, off the back of the engine cases,
doubt they'll hang in there for very long..... ?

Inneresting bit of racing history.
Off to a museum someplace, no doubt...
 
Now that I see the other side of the bike the sprocket is inboard and the brake disc is outboard. The swingarm is very narrow like you said. Sold for US$ 44,850 inc. premium
 
Spiermoor,

One day you will come for a visit and see some factory Norton racers that will blow your mind. One of the Cosworths sits 30' from my desk every day.

If historic race classes were based on technology and capacity rather than year of manufacture, such bikes as the Challenge would be much more valuable and there would be more copies made. It breaks my heart to see something so beautiful considered to be totally obsolete.

I was always disappointed that it didn't get into production as a road bike.
A smooth watercooled twin with (hopefully) solid gearbox and bottom end and an up-to-date top end
would have been a worthy addition to Nortons product range.
Alas, not to be....
