Ocelot Suzuki GT750

Updated my Ocelot photo set with al lot of new pics of a white car. This 1973 Ocelot Mark 3C was formerly owned by Indycar team owner Ed Walsh Jr. and competed in SCCA D Sports Racing events until it was donated to the Indianapolis Motor Speedway Foundation in November 1982. The car features white fiberglass bodywork over a tubular steel chassis. The water-cooled, two-stroke GT750 Suzuki inline-three features a Bendix servo fuel injector.

Featherbed Kawasaki triple 500

Wietse Veenstra on his Norsaki 500. In 1969 Wietse started racing in the 500cc national class in the Netherlands. First on a standard Kawasaki 500 triple, after a hard crash the Kawa was total loss. With the engine out of the wreck and a Norton featherbed frame he made this bitza. The thing was very fast and in 1971 he became the Dutch national champion in the 500cc class with 5 wins and 2 second places. I would really like to know what became of the bike, you can email me via the contact page on this site.

Valentino Rossi and the NSR500

Valentino Rossi on his favourite bike the mighty NSR500. On this bike he became world champion in 2001, he was the last one who did this on a  500cc two stroke. That 2001 NSR500 holds a dear place in Rossi’s heart. There's none other like it, and it's quite literally a money-can't-buy machine. It’s the bike that Honda was supposed to give to Valentino but the bike never arrived in Tavulia. In the last race of the 2021 season in Valencia, Rossi's fare well race, Valentino was reunited with the bike and asked Alberto Puig if Honda change the idea and gave the bike to him. Unfortunately that did not happen and the bike is back on its journey to the Honda museum.

Nico Bakker Yamaha RD350

In 1983 Suzuki introduced the box-section aluminium frame to the world on the Suzuki RG250. In Japan this type of frame was an instant hit. In 1984 The Dutch frame builder Nico Bakker received a rather suprising phone call from a Japanese motorcycle dealer if he could make such a frame for the Yamaha RZ250. They made a deal for 50 frames, Nico used a brand new RD350YPVS as a reference point. The alloy frame became 6.5 kilo lighter than the original steel frame, it had all the mounting points for the original bodywork. Two of the frames stayed in the Netherlands, one of these is the yellow bike in the photo set. It was equipped with a lot of special parts like an alloy tank, PVM wheels, WiWo brakes and a White Power shock. How many of these bikes still exist in Japan? The 2 Dutch bikes survived.

KTM 700 twin

This KTM 700 twin two stroke was made by Jerry van der Heiden for Dutch sidecar cross ace Ton van Heugten. Jerry many thanks for the pictures of this very trick engine! The twin consisted of two KTM 350 cross engines grafted together. Just one gearbox and final drive are used. The engine sits normally in the frame and the second cylinder is pointing directly forward. It's mounted to the front half of a KTM 350 lower end that is attached to the right side of the complete 350 engine. The cranks are timed so that both pistons move identically, and it fires as a single. Ton van Heugten won his last sidecar cross with it. Jerry made a total of 7 engines, most of them still exist today. It all started when Rudi Kurth made Yamaha 500 triples in the seventies for sidecar racing, he also grafted an extra cylinder to a twin. Jerry repeated this idea when he made a 350 triple for Takazumi Katayama, Katayama became world champion on a bike with such an engine in 1977. More about Jerry and this bike in a later post.
