Seeley Norton 750
When function defines form, the results are often
spectacular. And so it is with this lovely vintage racebike, one of the stars of
Cafe Racer TV. Built by four-time AHRMA National Champion Kenny Cummings of NYC
Norton for Dan Rose, the bike is a modern take on the classic Seeley Mk II
Norton racer. Its pedigree is perfect: for starters, the frame was
hand-fabricated by Roger Titchmarsh in the UK, the only man permitted to
replicate the original Colin Seeley design.
And it weighs just 24lbs (10.9kg), including
bearings, bushings, and chain adjusters. (Bonus: this design also allows you to
remove the cylinder head and block without taking out the engine.) The Norton
Commando 750 motor was assembled using racing components, and theres hardly a
lick of paint on the unfaired bikejust bare metal.
Checking the specification reveals a remarkable
amount of skill and knowledge going into this build. Its craftsmanship of the
highest order, using period-correct componentslike the Norvil 6-bolt racing
front hub, AP Racing calipers and 70s-era Brembo brake masters. The suspension
looks equally vintage, but has actually been heavily upgraded by specialists
Cosentino Engineering. There are modern Showa fork internals with adjustable
compression, pre-load and rebound damping. The back end is supported by Works
Performance shocks.
The engine merits a whole article in itself, being full of trick parts from JS
Motorsport and Steve Maney, and topped off with a Fullauto Technologies 850cc
head with 33mm inlet ports.
The specs match the AHRMA vintage motorcycle
racing regs for the Formula 750cc class. In essence, it means that most
components are limited to those you might find on a pre-1972 GP motorcycle.
Power output is around 70 hp, which is extremely good considering the regulatory
restrictions and 300 lb (136 kg) weight of the bike.
