Rob Bron

Rob Bron was in 1971 the first Dutchman to gain a podium place in the 500cc class, during the TT in Assen he finished as second behind Giacomo Agostini. He would finish third in the World Championship that year behind Agostini and New Zealander Keith Turner. Agostini was the only one in those days who raced with factory material (MV Agusta). The others, including Bron, raced on  production racers. He was racing a Suzuki TR500 under the flag of Dutch Suzuki importer Nimag. Bron is since 1971 the best-classed Dutch racer in the 500cc class. Wil Hartog, Boet van Dulmen and "Jumping" Jack Middelburg did not equal this.
He is still the holder of the maximum speed record at Daytona, in 1978 he topped a lap at 342 kph. He ended his career in 1985. From that time he started a motorcycle shop and racing service. His nickname was "Rough Robbie".
Rob Bron died in 2009 at the age of 64.

Pernod 250 - 1985

This bike’s frame was designed in 1985 by the Frenchman Alain Chevallier, at that time famous for his revolutionary bikes. Only one example produced! The frame was built with a steel frame (25 CD4 S) and titan. The engine is a rare bi-cylinder 250 cc with rotary distribution and magnesium carter, developed by the French engineer Jean Bidalot. This Pernod Chevallier participated at the 1985 season with Jean François Baldé. It was restored in 2007 and participated at the Varano Motor Show in Italy in June 2007, as in former times, driven by Jean François Baldé personally.

Ciba Geigy Suzuki V4

In 1986 the Suzuki factory stopped racing with the square four bikes and made a V4, the XR71. Team Heron was commissioned to make a frame. Nigel leaper was asked to built a new carbon fibre composite chassis for the XR71 engine, but it was never tested. The project was stillborn - even though comparison with the Suzuki alloy factory frame, by then standard for GP racers, showed that the carbon fibre frame was 1.3 kg lighter, as well as substantially stiffer. The weight with all the magnesium inserts was 8.3 kg, with a carbon composite swing arm - on a Heron design for the first time - scaling a further 6 kg. Though one of the 3 chassis found its way to Japan, the word came down from high, thanks but no thanks.
