Bikers’ Classic Spa Francorchamps 2012

Visiting Spa for the second time round is just as special as the first time. The track at Spa is a real rollercoaster ride, with changing cambers, uphill and downhill sections plus the added mix of unpredictable weather.



Featuring one of the worlds most famous corners, Eau Rouge, Spa is steeped in history. The Bikers’ Classic celebrated its tenth anniversary in 2012, and in addition to the annual public track sessions and GP demonstrations, the 2012 event hosted the return of the early 90s Superbikes, plus the 4 Hours of Spa endurance race – held at night!

If that wasn’t enough, the trade stands, live concert and electric atmosphere provided the ideal distraction.

We entered two bikes this year, myself riding the 1956 Norton Domiracer 500 and Bob astride the Norton Model 50 440, aka ‘The Green Meanie’.



 We also set up camp alongside Mike Pemberton of PushrodPerformance, and his wife June. Mike was riding his highly-developed red-framed Norton ES2 500.



Friday kicked-off with a dry session, a chance for track newbies Mike and Bob to learn the track while I settled in to riding the newly rebuilt Domiracer on track for only the second time. Mike recently rebuilt the Domi’s top end so I was under strict instructions to keep it under 5,000-5,500rpm, allowing the motor to bed-in.

Later in the day, humidity levels were very high and the two wet sessions provided a real test for our nerves. Several nasty looking accidents confirmed the low grip levels but we all came home safely. The day ended with a very dry warm evening, only heightening the excitement for the predicted dry weather on Saturday.

Saturday morning was glorious. Dry, fresh and much less humid, we were set for a great day of riding.

Three fantastic track sessions, plus a free t-shirt and a Belgian hamburger later, we also discovered that we were to be the first vehicles to circulate the original Spa Franchorchamps road circuit since it was last used in anger in 1978. Over 500 machines took to the closed public roads in a parade following the exact route of the very fast old track, passing through the infamous Masta Kink. The old track was eventually banned due to safety concerns from the drivers and riders. Despite not being born when it was last used, it was an emotional moment for us, the riders, as well as the countless local spectators who waved us round.



By 8pm, we were claiming our seats to watch the start of the 4 Hours of Spa night endurance race.

All entrants were dated pre-1980 with around 1000cc (or thereabouts), most machines sporting dual headlights in the style of the fantastic Bol d’or bikes.

Our three Nortons performed faultlessly throughout weekend, while the mix of dry and wet conditions served up a fantastic test of rider skill.

Despite the increasing amount of ear-piercing two-strokes and 2012’s Superbike theme, the Bikers’ Classic continues to serve up a brilliant celebration of classic and post-classic machines. Let’s hope the organisers target a 50s and 60s singles theme next year!

Norton Dominator racer

Originally capable of producing upwards of 50bhp at around 8,000rpm the works Domiracer was a very capable machine.

In the 1961 Isle of Man TT rider Tom Phillis took a Doug Hele-developed Domiracer to third place and lapped at over 100mph. This was a first for a twin-cylinder pushrod engine.

1956 Norton Domiracer

Once the Bracebridge Street race shop in Birmingham closed in January 1962, Norton abandoned the Domiracer project and the works Domiracer and factory spares were sold off to Paul Dunstall. Dunstall continued to campaign the 500cc twins with riders Fred Neville, Dave Downer and Syd Mizen, up until 1964.


This example features a 1956 wideline frame with Dural engine plates, Manx type swing arm, Hagon shocks, chrome short Roadholder forks with alloy damper tubes and a Seeley alloy top yoke. Front wheel is a WM2x18 Akront with Norton hub and a Triumph 2LS backplate. The rear wheel is WM3 Akront with Norton hub and cable brake. It is worth noting that the brakes are very effective!

1956 Norton Domiracer

The engine is Laystall short stroke (68x68), with one piece period race crankshaft fitted with polished and shot-peened Commando rods, SS camshaft with lightened followers, running 10.5 - 1 with Powermax pistons, gas-flowed head with lightened and polished rockers. The carbs are twin rubber-mounted (GS750 stubs) 28mm Amal MK2s. Total loss coil ignition system. Bob Newby clutch and belt primary drive with fibreglass primary cover. Close ratio 4 speed gearbox and custom-made, 2-into-1 Mason Racing exhaust.

I can't wait for a test ride once the 2012 season gets into full swing!

Norton Domi-Racer on Ebay

I spotted this interesting looking '59 framed Domi-Racer on Ebay this evening, how many have you seen painted green? Yours for £5,500.


The fibreglass tank would have to go! Some tasty parts though.


The owner states that the '53 motor comes with high compression, large valves and an alloy barrel. There is also a belt primary drive conversion and a close ratio 3rd gear.
