Ex Paul Hanson Barton Phoenix sidecar

Ex Paul Hanson 1980 Barton Phoenix 750cc Racing Sidecar Outfit

'During 1996 the Phoenix number 2 engine reappeared in the hands of Manchester sidecar racer Paul Hanson. Housed in a Derbyshire kneeler chassis the Phoenix was raced at a Forgotten Era meeting at Barkston Heath, after initially being outlawed on the grounds that it was too fast.' – Mick Walker & Rob Carrick, 'British Performance Two-strokes'.

This racing sidecar outfit was built in 1980 by its sole owner, Paul Hanson, utilising a new Barton Phoenix 750cc engine and a Derbyshire chassis. The Phoenix engines were produced in very small numbers, estimates varying between five and eight examples of the 750cc motor manufactured. Barton had been founded by engineers Barry Hart and Tony Ryan, and made its first impact on the racing scene with a three-cylinder water-cooled '500' based on the Suzuki GT380 bottom end. Ridden by Martin Sharpe, a Spondon-framed, Barton-engined 'Sparton' won the 1976 North West 200 with similarly-mounted Frank Kennedy in 2nd place, while the previous year Sharpe's bike had proved as fast as the works Kawasakis at the Isle of Man TT. The switch to a square-four engine came about after Barry Sheene asked Hart to convert an RG500 engine to 650cc, something the factory said could not be done. Hart nevertheless succeeded and used the knowledge gained to produce his own version of the Suzuki engine: the Barton Phoenix, initially as a '750' and later as a '500'. The Phoenix engine showed promise but the project never received the financial backing required to develop it, despite Hart's appeals to the patriotism of the motorcycling public and a deal with the Rank Organisation to provide machines for the 1978 film 'Silver Dream Racer' starring David Essex. Although it achieved little in solo form, the 750cc Phoenix engine enjoyed considerable success as a sidecar power unit in the hands of Nigel Rollason, whose first major success with it was a 2nd place finish in the 1979 Isle of Man TT. Rollason would go on to finish nine out of ten TTs with his Phoenix-powered outfit, eight of them on the leader board, the highlight being victory in the 1986 event. By then Barton Engineering had ceased to exist, having been purchased by Armstrong in 1981. Barry Hart moved to Armstrong as chief designer and would be responsible for its highly successful Rotax-based tandem-twin racers.

A well-known and respected sidecar competitor, Paul Hanson spent some time refining his outfit's engine and chassis, incorporating various developments such as Armstrong cylinders and an improved fuel supply system, a process that culminated in him winning the 1985 Formula 5 Championship with passenger Stuart Aspin. The outfit continued to be raced regularly until the late 1990s. Thereafter it was used only for occasional parades, the last outing being at the 'Festival of 1000 Bikes' at Mallory Park in 2010.

Ex Noriyuki Haga Suzuki RG400

Ex Noryuki Haga RG400. This Suzuki RG 400 is the Asian version of the RG 500 Gamma. This model was sold in Japan and only a few arrived in Europe. The 1988 RG 400 is the last 4 cylinder two-stroke with rotary distribution produced by Suzuki and equipped with a reinforced gearbox (1987/88). The here presented model is entirely original (unlike the RG 500, the RG400 was factory delivered without the lower fairing). The bike has run 18.746 km from new. This bike has a particular history which is of high value for a collector. It was bought by the famous Japanese World Championship rider, Noriyuki Haga, who had a residence in Italy. Haga imported the bike to Italy.
Year: 1988
Frame N.: HK31A-108374

Aprilia RSV and RSW250

Ex Anthony West RSW250. The Aprilia RSW250 is in my opinion the best and most beautifull 250cc racer ever build, it is a work of art!

Ex Frankie Chilli F1 RG500

Based on its World Championship-winning RG500 racer, Suzuki's Gamma roadster retained the same square-four engine layout, geared-together crankshafts, and disc-valve induction. A box-section aluminium frame, 'Full Floater' rear suspension, and triple disc brakes completed the picture. More racetrack focussed than Yamaha's rival RD500, the Gamma, with its 150mph (240km/h) top speed, 11.5-second quarter-mile time, and superlative handling and brakes, remains the closest anyone has got to offering a modern Grand Prix 500 for the road.
Not surprisingly, many found their way onto the world's racetracks, the example offered here being one such. It was prepared in 1986 for the FIM's production machine-based TT Formula 1 race series, which pitted 1,000cc four-strokes against 500cc two strokes. Its creator was the Italian Team Gallina, whose founder, ex-racer Roberto Gallina, already had plenty of experience of campaigning the Suzuki RG500 in Grands Prix, his riders Marco Lucchinelli and Franco Uncini having won the 500cc World Championship in 1981 and 1982 respectively.
In developing the Gamma for Formula 1, Gallina used many parts taken from his Suzuki RG500 Grand Prix bikes, including a magnesium dry clutch, Kokusan GP ignition system, Mikuni TMX 36mm carburettors, Tecnomagnesio wheels, braced swingarm, special exhaust system, Forcelle Italia fork, and more. Out of six starts in 1986, Chili scored five wins and ended up 3rd in the Trofeo Grand Prix F1 and 4th in the Campionato Italiano F1. Frankie Chili went on to race for Gallina in Grands Prix, but it was his switch to World Superbike racing in 1995 that set him on the path to real success. In a 12-year career in WSBK, he scored 17 race wins and twice finished 4th in the Championship. The full story of the Team Gallina Suzuki Gamma is recorded in an article in Motociclismo d'Epoca (copy available). Believed to be the sole survivor of the three machines built, this ex-Gallina Gamma was raced many times by the vendor in 2014 and 2016 in the Italian Old GP Championship. It was photographed at the Varano circuit on the 50th anniversary of the start of Roberto Gallina's racing career. Roberto Gallina's signature is on the fuel tank together with that of Vincenzo Biagioli, maker of the special cylinders.

RG500 hill climb cars

This time some pics of 2 RG500 hill climb cars a Jedi and a Nero, the Nero is the one in the pic. Some information about the Nero. The Nero PF1 is a single seater race car designed and built in 1992 for use in Formula 500 circuit racing, 500 cc class speed hill climbs and sprints. The mild steel space frame chassis has aluminium sheet riveted in place for added stiffness, and can take a wide variety of motorbike engines up to 1200 cc. The Suzuki RG500 Gamma engine is a unique water-cooled 4 cyl square configuration including use of power valves. This specific engine was selected because of its high power (over 100 bhp), low weight and low centre of gravity. In this particular example the drive is transmitted by chain to a modified Mini differential. Numerous Mini parts have been utilised to ensure ready availability of spares and low cost repairs (if ever required). Mini 10" solid disc brakes are fitted all round, including inboard on the rear. On a technical note the suspension (in board all round), has been designed so that bump stiffness is completely separate from roll stiffness. This provides excellent road holding and is another unique design choice.
