750 Kawasaki Endurance -1992

Small company, big ideas

Handbuilt racers often predict the features of forthcoming models from major factories. Though a small, highly-motivated team may be strapped for cash, it is more flexible and adaptable than a big company, which must consider factors of putting a design into production and whether it is risking its image by racing an untried concept.

Original Front Suspension

JBB - the initials are those of constructor Jean-Bertrand Bruneau- has for a number of years been working on an original design of front suspension incorporating superimposed wishbones with hub-center steering. The concept became particularly interesting in 1992 when Yamaha presented its new top of- the-range model equipped with a very similar layout. The little JBB workshop maintained its lead. While the new Yamaha was still just a show model, the latest version of the JBB - built with the aid of Vincent Sebileau - was racing in the Bol d'Or.

Aggressive Styling

The victim of growing pains, it finished down the field, though not without having shown

its potential with a speed of over 170 mph and outstanding roadholding, spoiled only by

a vibration period in the front suspension. The JBB is really eye-catching and is innovative yet not shocking, with its triple head lamps, huge tires, unorthodox suspension and light lines. The double-wishbone front suspension doesn't clip under heavy braking, and its geometry is completely adjustable.
