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.

Yamsel V4 500

This very special bike was built in 1974/75 by Geoff Sherwill and Lyell Williamson. Using 2 Yamaha TZ250 engines welded together and fitted into a 1971 Seeley frame. The original idea was conceived by Brian Thompson to create a wide angle V4, by using 2 Yamaha TR2 350 engines with carbs facing forward in the V. With limited budget and plenty ideas, Geoff and Lyell decided to build a R&D bike. Geoff undertook all the machine work and creating a jig/plate assembly, the case was welded together with both crank pinions driving direct to the clutch hub primary gear. This set up created extra long and angled inlet manifold tracts which wasn't ideal. To solve this problem Geoff was planning the inclusion of custom cast wide angle crankcases for the final engine. The first outings showed the engine to be reliable and only minor issues with cooling and ignition were evident. With Lyell riding the bike for 3 years and with ongoing modifications race results were several placings together with some top ten finishes. It was last raced in 1979.

Chassis: 1971 Seeley
Forks: Yamaha RD350
Yokes: By Geoff
Swing Arm: By Geoff, using yacht mast, no square or rectangle extrusion available back then
Wheels: By Peter Allen & Jack McDonald, cast at Commonwealth Aircraft Corporation
Tank: By a friend of Bill Horsman

Yamaha F1 RD500

Here we have some nice information and pics about the Yamaha F1 RD500. Just as with the RG500 several people tried to make an F1 racer of the Yamaha RD500. The Yamaha never reached the success of the RG500.
