1000 Endurance I 950 SS -1973
Star of the Bol dÂ’Or
The biggest Honda retailer in Europe, Christian Vilaseca was a great sports type, when he mounted his attack on the Bol d'Or in 1970. Not content to enter a Honda, Vilaseca wanted to run a bike bearing his business's name - Japauto. The famed 750 four had its displacement increased to 946cc, a second front brake disc was added downstream of the first and the whole was dad in a full fairing.
Biggest Was Best
In 1971, the japauto - the biggest displacement bike entered for the Bol d'Or - finished
no better than 20th, but Vilaseca achieved his goal in 1972, when the Japauto of Ruiz / Debrock won the famous race.
In 1973, the ]apauto sported a new wedge-shaped fairing designed by Motorcycle Sport Design, as voluminous as it was original and very aerodynamic. The comfort it gave Â– exceptional for an endurance bike - was greatly appreciated by Debrock and. Tchernine, who, despite bad weather, won a second victory in the 1973 Bol d'Or. In 1974, the Japauto adopted four-pad brake calipers and a frame built by PEM, following the Honda layout. Vileseca executed a more personally-designed frame for the 1975 version. Even before these successes in the Bol d'Or, Vilaseca placed a version of this bike on sale under the name "950 SS." In fact, it consisted of a kit including four sleeves and four pistons (made in France), plus a complete cylinder block, a second front disc brake and an iodine headlamp. In 1971, fitting the 950 SS kit added over 30 percent to the cost of a new 750 Honda.
