Road & Track: A streetable Seeley G50 from NYC Norton

New from NYC Norton: A Seeley Matchless G50 racing motorcycle
I’m sure most folks have a ‘lottery list’ of bikes they’d put in their garage if they won big. And on my own mental list I have a restomod Commando from NYC Norton.

That might have to change though, because this Seeley G50 is even better. Kenny Cummings built it for the Custom Revolution exhibition at LA’s incredible Petersen Museum, and although it’s powered by a short-stroke replica Matchless Grand Prix motor, it’ll be made street-legal when the exhibition has run its course.

“With all the publicity around the Petersen show, I really wanted to submit a street bike,” says Kenny. “NYC Norton is well known in racing circles but the race market is relatively tiny.”

The story behind this G50 starts five years ago, when Kenny raced a 500cc Seeley Matchless G50 at Cadwell Park in the UK. He was impressed by the bike, despite being already familiar with the Titchmarsh Seeley MK2 chassis. (Kenny has won four American National 750cc Championships on his own Seeley 750 Commando.)

“The G50 was tight and very precise,” Kenny recalls. “But what completely blew me away was how much lighter and more nimble the little 500 was, compared to the 750—particularly in the tight stuff.”

“The torque and power curve was wonderful! It felt like a trout swimming upstream, effortless against the current.”

Back in New York City, Kenny [below, left] knew he had to get a G50 to campaign in the USA. And so he did. After a season of racing, folks started taking interest, and NYC Norton has now built a salvo of Seeley G50s for clients in the US and beyond.

“G50s are a still a small corner of NYC Norton, but not insignificant,” he reveals. “Their main appeal is to racers, of course, but we have a road-trim version in the wings.”

One of Kenny’s clients, Helmut Niederer, commissioned two Seeley G50s. And he also secured a spare ‘92 bore’ motor from Minnovation Racing, as insurance before a trip to Australia’s Phillip Island track—which is notoriously hard on engines.

“We made it back from Australia with zero technical issues, so the spare motor sat in its crate, untouched,” says Kenny. “We suddenly found ourselves with the world’s most exotic paperweight.”

Then Kenny received an email from The Vintagent himself, Paul d’Orléans, asking if he’d be interested in building a bike for the upcoming Custom Revolution show.

A call was put in to Helmut and a plan was hatched. “We’d shoehorn his G50 motor into a Seeley MK2 chassis in racing trim, and convert it into street trim once the show completes its run.”

Kenny acquired a frame from Roger Titchmarsh, the only frame builder recognized by Colin Seeley for continued chassis fabrication. Engine plates were made up, a TT Industries 6-speed close ratio gearbox was bolted on to the motor, and replica Ceriani forks were slotted into the triple trees.

“Our Seeley recipe is familiar, but each bike is hand made,” says Kenny. “No two are ever exactly the same. We put extensive time into engine/gearbox alignment, driveline alignment, offsets, fabrication, tuning, and so on.”

The Seeley took shape in short order—but the bodywork needed some consideration. “We love our shiny polished alloy tanks and black fiberglass racing livery,” says Kenny, “but this bike needed something more.”

“Helmut was always intrigued by our NYC Norton logo. Why did we choose a decidedly 1980s teal blue, as opposed to a more traditional motif?” says Kenny. “I could never answer this question. So a plan was hatched to color this bike in a pale blue inspired by our logo. ‘Blue Monday’ it became.”

Brent Budgor from The Vintage Vendor in Vermont shot the paint. “I have a tendency to micro-manage, but painting is not my skill,” Kenny admits. “I told Brent that time was short, so he dropped what he was doing and made it happen.”

“I never told Paul d’Orléans what color I was doing, though—he wanted pink! When I sent him photos, he was ecstatic.”

NYC Norton has always built bikes that prioritize function over form, whether they’re road-going Commandos or highly-specc’d racebikes. But there’s beauty in the details here, from the replica Fontana hubs to the custom-fabricated rear sets, and the high performance shocks built by Cogent Dynamics of North Carolina.

“We spend time to make our builds pretty,” says Kenny, “but they must first handle, then stop, and then go. This G50 is no exception. It’s ready to race, and it’s even safety-wired—just add bean oil and go!” And go it will: dry weight is a mere 245 pounds (112 kilos).

Paul d’Orléans knows all too well about customs and their nuanced forms, and this Seeley G50 will dovetail nicely with Alp Sungurtekin’s Triumph land speed racer—and Revival Cycles’ J63 bridging the race-to-street gap.

And when the lights are dimmed on the Petersen exhibition in 2019, the G50 will get a charging system, a headlight, and a brake light. And into the sunset it will go.

If your appetite is whetted, drop Kenny a line. After all, there aren’t many customs with a major museum pedigree—let alone ones that will also happily run on the streets.

Sunburst: NYC Norton’s dazzling 1972 Commando

Sunburst: A dazzling 1972 Seeley Commando from NYC Norton.
If you live on the east coast of the USA and you need work doing on your Norton, there’s only one person to call: Kenny Cummings of NYC Norton in Jersey City, just outside Manhattan.

Kenny’s a household name on the global Norton scene. It’s not hard to see why—his builds are an exquisite blend of performance and style. And, as with most old British iron, there’s usually a good story too.

Sunburst: A dazzling 1972 Seeley Commando from NYC Norton.
Sunburst started with a call from an overseas number on the shop phone,” Kenny tells us. “On the other end was a pleasant voice with an unidentifiable accent. It was Joe, calling from a small country in the middle of the Mediterranean.”

Joe had just bought a pristine Norton Commando in the States, and asked Kenny if he could add some performance and reliability mods. “We love that kind of work,” says Kenny. “But Joe’s Commando was just too nice to tear down.”

A new concept was required, and a ratty 1972 Commando appeared on the radar. It had lived a rough life: the crankcases even had a sloppy weld on the drive side half, a telltale sign a rod had broken through.

Kenny decided to use as much of the donor as he could, while fitting some robust and reliable racing parts. He sourced a Maney lightweight crank, alloy cylinders, a Fullauto head, and JE 73mm forged pistons. The crank was balanced to 74%, the same factor used by NYC Norton’s championship-winning Seeley Commandos.

Other goodies include a Webcam racing cam and one of the last Maney exhaust systems ever to be made. “We kept the compression close to 10:1,” says Kenny. “High enough so the bike can be ridden on the street, while still being able to run on hi-octane pump gas.”

Carbs are Keihin FCR35s, with manifolds adapted to the Fullauto Norton cylinder heads. “The heads are the single biggest boost of power you can add off the shelf for your Commando. Proof is in the pudding, and the eating is good.”

Metal-bending artist Roger Titchmarsh supplied a mint Seeley Mk2 replica chassis from the UK, and Kenny started fabbing up custom engine plates. “We spent a lot of time spacing the AMC gearbox over to the left, five millimeters from the motor centerline, to give better chain clearance for the back tire.”

A pair of custom alloy fork yokes went on, set up with a pinch-bolt top for quick geometry changes. Falcon shocks were fitted to the rear.

For the front wheel, Kenny bolted twin Hemmings 11.5-inch disks to a 6-bolt hub using AN aircraft bolts. The fork sliders are Norton Production Racer items and the disks have been drilled—removing 1.3lbs from each rotor. The calipers are AP Racing, pumped by a 16mm Brembo master cylinder.

The rims are 18-inch unflanged alloy, WM3 at the front and WM4 at the back. A neat touch: the rear wheel was built using a two-piece Triumph T140 replica billet hub, along with a Maney cush drive to give the gearbox a little relief from quick shifts and injudicious throttle use. Tires are Bridgestone BT45 Battalaxes.

The primary side of the bike was built using a 30mm belt drive that increases the primary ratio—meaning less torque shock to the gearbox. There’s also a trick high-output alternator, keeping a low profile behind the alloy belt guard cover.

The bodywork is equally divine. “Joe turned us on to FlatRacer in the UK and their Sprint 1/2 fairing,” says Kenny. “It’s heavier than the racing bodywork we often use, but that allowed us to alter the shape of the fairing to get the custom fit we needed.”

The vibrant color scheme is certainly a departure from the more conservative natural alloy or black and gold chosen by most of NYC Norton’s Seeley customers.

“Joe knew he wanted something bold, but he wasn’t sure exactly what. After much back and forth, we seemed to stall a bit.

“Later, while sitting in my home studio, an idea dawned on me as I sat plunking out some parts on my guitar. I realized this was a motif that was very important to me—the cherry sunburst of my favorite vintage Gibson Les Paul.

Joe was 100% on board. “This made it very personal. The last philosophical hurdle had been cleared.”

Kenny’s go-to guy for paint is Brent Budgor from the Vintage Vendor. “As we worked through the shading process of the sunburst motif, I learned that Brent too had a Les Paul that he’d stripped and painted—so he understood the concept from the get-go.”

Brent laid out the Norton logo and pins in a gold undercoat, then sprayed the major color over. Once the bodywork was back, the bike was buttoned up in short order. Kenny called his old friend and fellow racing competitor, the photographer Doug MacRae. It was time to shoot.

“This is a serious bike,” says Kenny. “It’s pretty, but its foundation is a top-spec, competitive 750 racer weighing 300 pounds, adapted for the street.

“The bike starts on first kick and is an absolute blast to ride. It has the famous Seeley handling and Commando torque, without any sacrifice. No, it is not Papa’s Norton, and perhaps the cobblestones of NYC streets might rattle its tight suspension a bit.

“But there’s not a back road in the world this bike can’t eat alive.”

The NYC Norton site has a wealth of riveting detail on this build. But don’t head over there unless you’ve got time to spare—and a firm grip on your credit card.
