Model 80 – Kit Campeon
The oldest machine here is the model 80, the so-named kit Campeon or slim-line, built in 1971. The Bultaco is a 250cc with five gears, still with original frame and front forks and the fibreglass one-piece tank and seat which still in the modern world looks very cool. In its original condition this model was a little difficult to ride in hazards when sharp turns were necessary, and for this reason some minor modifications have been carried out to give it a more modern riding style without changing the basic characteristics. The footrests are lowered and moved backward, and more modern rear shock absorber units replace the original ones. This modification, in association with the new superior fork yoke fitted from a modern machine and then modified, puts the handlebar in a more advanced position which makes the riding characteristic of the machine much more modern.
For weight saving all lights and associated electrics are removed and the front wheel rim has been replaced by one from a Bultaco 199A model. With a very high handlebar position and the rear brake pedal now on the right-hand-side the modifications are complete. With the rear brake pedal on the right-hand-side it means that you have the brake and the gear change lever on the same side. This is not ideal and a little strange when you are riding but the model 80 engine does not allow you to make any easy changes to swap over the brake and gear pedal arrangement. A new pair of Betor rear shock absorbers works well on the rear. An ex-Ossa sump shield protects the frame and modern Michelin trials tyres help in slippery conditions.
Regarding the engine no modifications have been made, and the unit is a standard one which is very smooth and sweet to ride. To give the machine a little more ‘punch’ a bigger rear sprocket has been fitted and the rear silencer has been modified. An Amal carburettor from a Bultaco 158 model is fitted as it’s easier to adjust and is easier to tune.
Justyn Norek Jnr: “The looks are so retro; and super cool despite the passage of time for this beautiful looking machine. The idea of an upgrade kit worked so well and you can imagine how many happy Bultaco owners there were. Performance wise the power delivery is very good and the smooth delivery inspires some easy riding. Handling wise it feels very low but despite the modifications carried out by Riccardo it’s still uneasy on very tight corners. This model Bultaco is far happier on straight, open hazards such as in a river bed and holds the line very well on this type of terrain. I can image back in the early seventies that the red, smooth look gave it the Ferrari-inspired feel to its proud owners.”
