To a lot of dyed-in-the-wool Norton enthusiasts, a road going manx would be the ultimate road bike.... ??
And was the model that Nortons didn't ever make.
So a secondary reason for doing one.
Nortons had done race replicas since about, Oooo, 1910 or so ?
You could buy the Brooklands Road Specials all through the teens.
Belt drive, one speed, no mudguards !!
Oooo aaah ! - and sold like hotcakes...
Then the Model 18, CS1, Inter.
But no dohc version.
And even a sheep-in-wolfs-clothing JPN Special (ie Commando cafe).
Hmmmm, that old featherbed in the corner should take a manx engine.
Hmmmm....
