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.

Suzuki RGB500 MK9 X3

A 1984 Suzuki RGB500 MK9 Factory/Production prototype designated "X3". One of only five Factory prototypes produced in this last year of RGB500 production and developement. (Just 25 production Mk9's made in the same year.) It has a fully rebuilt MK9 engine with many new parts. Specific X3 marked, magnesium Mikuni carbs. An oversized Factory radiator. A "one-off" Factory fuel tank. Electronically powered tacho. 17" Campag front wheel, 18" rear wheel. New Avon tyres. Fully overhauled original front calipers and new discs. Has an aluminium Factory frame (number X3-RGB500), swingarm and yokes.
There were 3 base models of Suzuki RG500 production bikes through the years. The MK1 till 6 based on the XR14, the RGB500 MK7 and 8 based on the XR22 and the last versions the MK9 and 10 based on the XR45, equipped with exhaust valves and alloy frames.
In 1985 Suzuki opted to stop producing complete RGB500's, instead supplying Padgett's of Batley with up rated, magnesium cased, stepped RGB500 engines and their associated power valves and expansion chambers. Padgett's would then supply complete machines using a steel frame built by Harris Performance and based on the Suzuki Mk7/8 frame. A total of twelve engines were supplied to the Yorkshire based company with machines being built between 1985 and 1988.
One of the last bikes an MK14 was ridden by Darren Dixon, a Padgett's sponsored rider to victory in the 1988 British F1 Championship.
Not only Harris made frames for the RGB500 engine also Spondon, VRP and Nico Bakker did, they even made Delta Box frames in the last years.

Superkarts

Dea superkart engine
Seen at the Gamma Racing Days 2018 at the TT circuit Assen. As a two stroke fan the superkarts are amazing! Take a look at the pictures of the engines, great two stroke technology with more horsepower than the last 250 GP bikes.

Riemanoc Suzuki TR500
This time I made a photoset of some very rare race bikes, made in Holland. These bikes were designed by Frans van Manen, Ton Riemersma the man who also was the sponsor of Wil Hartog was the financer of this project. These bikes all had an alloy monocoque frame, the name is a combination of Riemersma and monocoque.

Seeley Crescent 500

This time some pics of a very rare bike, the Seeley Crescent 500. This bike uses the same speedboat engine as Rudi Kurth did in his sidecar. The engine a 500 two stroke triple was very fast but not so reliable.
