Yamaha FZT 900 Dakar 1987

Three straight victories in the BMW decided in 1986 the Honda, that to return to success at the Paris-Dakar rally was necessary to play the card of two-cylinder motor. The only choice to keep up in long stretches of desert where most top speed allows two cylinders to buy a house edge that they take shelter from every retrieve while agile «mono». The Yamaha decided, Instead, to confirm the single cylinder after it was breezy the construction of a twin-cylinder to be entrusted to the French team.
The response of Jean Claude Olivier, team manager of Sonauto, was the manufacture of a prototype driven by the engine of FZ 750 twenty valves. An adventurous project, who did turn up their noses to leaders of the House of Iwata, but not to the point of rejecting the idea of pilot who in 1985 had arrived for second in Dakar.
The four-cylinder engine for the desert has begun work late and the test bench of the giant French-Japanese enduro was precisely the slopes of Paris-Dakar. It was a single copy, and get him into the race it was Jean Claude Olivier.
Doing so gave up departing at every chance to win a ride a motorcycle that was providing Yes a power of 90 HP but whose weight was about 270 pounds in running order.

In 1986, JCO ended the race 12th, pulled over 10 hours behind the winner, but brought the bike up to Dakar.

An important milestone that convinced Olivier to insist on the road taken. And so these days has been completed the Yamaha FZ 900 T Evolution 1, the bike which Olivier and Serge Bacou will lead to far more warlike purposes of those Dakar enlivened the expedition ' 86. At first glance you understand that this is a completely new bike without any piece in common with last year's experimental version.
You have done a great job of lightening and end the engagement was awarded by dry weight slightly less than 200 kg (20 pounds lighter than last year) and above all, a subdivision of the masses which is nearly optimal 45% the front and the 55% the retro-train.
The frame now has an aluminium bottom cradle (removable) and to eliminate the problems of spin ratio was decreased the maximum power for the benefit of better dispensing. In addition, always at the direction of Olivier, was increased the engine capacity.
The result is a total displacement of 911 CC and a power not exceeding 85 HP, 53 of which are available at 4.000 RPM.
In tests carried out in August in the desert of Tenere FZ 900 T has shown it can travel in a straight line at a speed of more than 160 km/h (as an indication, the «mono» ' 87 in the hands of Peak did not go beyond the 135 km/h) and on a technical course around Agades late against the mono did not go beyond the second one-and-a-half kilometer.
Even the tires have made huge progress in both grip under acceleration, lateral stability and still life. Conscious of the progress of the four cylinders, that could be the surprise of the Paris-Dakar ' 87, but also of his handicap (weight, encumbrance, mechanical complexity) Olivier has preferred to follow as last year two parallel roads. He and Serge Bacou will guide the FZ 900 T while Thierry Charbonnier and (in all likelihood) the American Danny La Porte will be racing with the single winner of the Rally of the Pharaohs with Franco Picco. You never know…

Ecureuil 1000 – Dakar 1987

We find and report this article taken from the site www.classic-motorbikes.com

"Hubert Rigal, our expert and former participant in the Paris-Dakar was able to find, After a year of surveys, one of the most surprising among the prototypes of the years ' 80 who participated in the world's toughest rally. It all started in 1986, When the technician Joël Guillet and reporter Pierre-Marie Poli, Chief Editor of the French weekly Moto Journal, came up with the idea of a revolutionary bike.
Promoted by the Cassa di Risparmio Écureuil, the eponymous racing team Écureuil was created with the aim of entering the world of the Paris-Dakar, outstanding media vehicle of the time.

Powered by a BMW (the brand that won the 1983 and 1985), the particularity of this “ERS 1000” is its modular conception and carbon as a material that distinguishes.

The design consists of three parts:
– A Kevlar-carbon body weighing just six pounds,
– The engine-transmission-rear wheel assembly,
– The front suspension, attached on the front.

The main advantage is the quick fitting: It only takes six minutes to remove the engine and transmission! This makes it easy to adapt the bike to the challenges of each stage.
In 1987, three Écureuil entered the race, led by Pierre-Marie Poli, Marc Morales and former policeman Daniel Pescheur.
Parker never made it to arrive in Dakar, Pescheur's bike caught fire in the desert and Morales, Although arrived at the finish was not qualified. Actually, during the last leg, Marc Morales was ranked 7th overall, was walking near the Lake Rose (Lake Retba), just three kilometres from the finish!

This bike is complete and original with the exception of the headlight protection, that could easily be reproduced.
According to need is equipped with front wheels from 18, 19 or 21 inch.
The engine, a 1050 model 1023 CC prepared by Herbert Scheck (the well-known German driver and BMW), and been ordered directly from BMW France.

The bike is equipped with a Marzocchi fork and two rear Öhlins, the chassis and the suspension fitting of the engine are honeycomb and carbon were built by ERS.
The bike is available in France, without valid entry documents for road use. Actually these prototype raced with registration documents which corresponded to a production motorcycle. "

That You Struggle…the Dakar! The BMW of Birbes Dakar 1987

Struggling and Charles Edson. after previous experiences at Pharaons Rally of the editions ' 84 and ' 85, you were made to clear and precise idea of how it was to be a bike able to compete for victory. First of all a reliable two-cylinder engine and can guarantee high speed and an indispensable strength on long desert marathons.

Obvious so the choice of BMW also considered that Charles Edson, the German House, It was the official dealer for Brescia and province.

"I had in mind the motorcycle of Rahier» – Silvio begins Struggling – "I wanted to make an equal and if possible improving it. My ideas, After nearly ten months of work, led to this result which I am satisfied».

In fact, after almost a year of Saturdays and Sundays stolen from family and rest, the object that came out will satisfy Birbes who after the first tests on the track of Rezzato, He expressed himself in terms very favorable.

«The motorcycle in principle is valid. but we have yet to perfect the front suspension 'cause. with a full tank of gasoline (60 liters), go to the bottom racing».

If we consider that this BMW-Struggling with a full tank of gasoline weighs about 240 kg, almost less official German motorcycle. We can image into their efforts to arrive at such a result.

What difficulties have you encountered in the realization of this «monster»?

«I had to lengthen the swingarm to nine centimeters by rebuilding so the entire transmission» – meets Struggling – "I have completely redone the back of the frame to allow easy positioning of the spare tank in such a way then you can disassemble the motorcycle without encountering too many difficulties. Now I'm able to intervene on the gear and the transmission without dismantling the Middle».

BMW-Struggling will start in early October to Marseille where they will do the ' 86 Edition hallmarks of Rallye des Pharaons. The result of this competition will also depend on the participation in the Paris-Dakar rally which will start on January 1 next. (Ed. Charles Edson arrived 6° in that issue of the Pharaohs).
«Subscribe to Dakar» – concludes Charles Edson – ' has already been performed. but the result of the ' Pharaohs ' will influence greatly on our participation. I think I still have the bike suitable for these marathons».

We leave Birbes and Struggling to hundreds of questions that fans and onlookers turn to them to know "why and how" of their realization. The similarity with the official BMW motorcycles is truly remarkable, but the bike though is the result solely of ideas and of Silvio Struggling.

We Thank David Baez (proud owner of the bike) for the material provided to make this post.

Project Squirrel ERS 1000

In 1987 It presents a motion from the project very interesting, the Ecureuil 1000 ERS conceived in 1986 by Joel Guilet (Ducati rider at the time Bol d'Or) on the initiative of the journalist and driver Pierre-Marie Poli.
Equipped with air cooled boxer engine BMW 1020 CC, 80 HP / 6500 RPM / min (engine preparation made from Arcueil Motor).

Tank 64 litres made of soft rubber,
Dry weight 170 kg dry weight and 250 kg with full,
Speed 195 km/h.

The originality of the ERS 1000 resided in its modular frame and carbon all disassembled very quickly, in just six minutes giving access to motor and transmission. This feature allows the ability to change the weight distribution and vary the distance. The project will be brought to the Paris Dakar also in 1988 and 1989.
