Peak 87

Dakar 1987 – Belgarda, New, confidence in the mono

After Marinoni's forfeit is Peak the foreman

Yamaha's credentials after Franco Picco's success in the Pharaohs Rally – Belgarda are very high; the value of the pilots is out of the question: they'll go down in the race Peak, Medardo and Fat to replace Andrea Marinoni who won't be able to DAKAR 87 Peakrun because of the aftermath of an accident.

There remains only one mole: The bike is always the 660 Thumper. Light, handy and reliable, complains about the power problem, and therefore the maximum speed, compared to bmw and Honda twin-cylinder bikes and Yamaha itself 900 four-cylinder used by the French.

Lately, Paris-Dakar has been dominated by large. motorcycles that allow you to go to almost 200 Kirih in the immense desert sand straights and gain time against the smaller monocylidrids. The choice of Belgarda, New, Instead, seeks to take advantage of the skills of handling and more simplicity and mechanical accessibility.

A project also linked to the commercialisation of the means: although modified directly by Yamaha racing department in Japan, le Hold 660 reflect the characteristics of the standard product. The power has been increased to more than 50 HP, The capacity of the tanks is 55 while the dry weight barely exceeds 150 Kg.

Features that in Yamaha's own plans should allow it to face the various multi-cylinder and recover in the paths of the savannah the time lost on the long straight stretches of desert.
Of the same opinion is also Peak: "To win the Dakar, it is not enough to have so much power. Others Picco_Auriol_Neveu_1987they'll go stronger, but driving a heavier bike also requires more physical effort. After many stages, fatigue can play a key role in not increasing the risk of falls and getting to the bottom.".

You have a little regrets about not being able to run with the FZ 900 bacou and Olivier will use?
"The French have been carrying out the FZ-derived engine design for some years, but so far they have not been able to gather positive results. I hope, because the brand to be defended is the same, whether it's a good year, but I've never tried it so I can't say anything. Let's wait for the Dakar to finish, we'll talk about it for the 88th.

Yamaha Belgarda working to the Dakar 1989

Insiders say the race, on the beach in Dakar, It doesn't end, but begins. In the sense that the losers, But even the winner, just crossing the finish line Let's start already thinking about the next edition. Behind the three-week race, In fact, There is the work of a whole year. But how does this work? As you work in “bunker” Racing divisions when the desert is back on silence and the wind has obliterated the footprints of tires from sand? To answer we checked into one of these departments ran (usually strictly “top secret”), one of the newly formed BYRD, (Belgarda Yamaha Racing Division), “daughter” Italian importer of Yamaha, that takes care of all the racing activities of the company.

The team has the credentials to be among the protagonists of the marathon and she collected many successes in the past in Africa with strong Franco Picco, second in Dakar last year and winner of the Rally of the Pharaohs in 86, and with Cyril Neveu, winner of five Paris-Dakar. Daniele Papi, Managing Director of-BYRD and head of African expedition, tells “Motorcycling” as the team prepared to “Dakar”. The rule of “Paris-Dakar rally which starts on the beach in Dakar when ends the previous edition” PAPI confirmation: the leaders of two official Yamaha team, the Italian Belgarda and France's Sonauto, gather together with observers sent by the Japanese parent a few hours after the end of the marathon in a private room at a hotel in Dakar.

The discussion, sports only cutting, need to analyze the progress of the race and has followed the week after, at the headquarters of Yamaha-Europe, in Amsterdam, where you decide the address of competitive activities of the three teams — French, Italian and Japanese — while in Europe you disassemble and inspect all parts used on motorcycles who finished the race, in Japan we lay the foundations of the project for the construction of the new machine. After a few months, completed the analysis of the materials used and the strategies of the next edition (number of motorcycles in the race and its assistance), starts the phase “hot” the preparation: mechanics and drivers flying in Japan for the first tests of the new medium. This last phase lasts between 30 and 60 days and is undoubtedly the most interesting: It is here that the prototype takes form and is changed according to the recommendations of the pilots, recommendations taken into great account of Japanese technicians.

The new Yamaha OW94, Thumper of 750 CC., in first exit at the rally of the Pharaohs finished second with Franco Picco. Digitalis is placed in the tail of the bike, away from the engine that could create abnormal magnetic fields, the reader is at the side of the road book.

OW94-02Our peak, in particular, enjoys fame as expert test pilot and the Japanese are doing everything to please him making changes that suggests. So we arrive in September, When you debug the participation to the Pharaohs, dress rehearsal of “Dakar”. The bikes come from Japan and intensify testing of parts produced in Europe, for example the rear shock (Ohlins): in the race, then, you will experience the new solutions.

Upon returning from “Pharaohs” life gets hectic: expect from Japan the new bikes, amended in accordance with the experience of the race in Egypt, bikes arriving anco-ra to assemble and check. The last test was completed a few days before departure for Paris. Janice Bailey, Head of external relations of the BYRD, It acts as a guide during your visit to the bunker. We begin with the presentation of full-time employees • mechanical Racing Division: named Fumagalli, Lanzulli and sinks, While completing the Paris-Dakar Bonetti (that follows Fain in cross) and the specialist bodies Vafaie. The new regulation, prohibiting participation in the truck and that limits the number of support vehicles, He forced all the major team to review the Organization of assistance in race.OW94-07

The 70 percent of spare parts is carried on cars and trucks, the rest being parked at Agadez, in a permanent base Yamaha. The tires needed a race like that between moto, cars and trucks are almost two hundred (an idea of the total cost may give it the price of a special rubber for trucks, 2.500.000 Italian lira). Motorcycle tires are replaced each end stage: the Special “mousse” (Michelin) that substitute for normal air chambers prevents punctures, but it has a limited tata resistance to high temperatures that occur in stressed tires. The three Range Rover (participating in the race) take care the parts most commonly used screen on the slopes, a motor mounted, a tank, a complete wheel and obviously a mechanic can assist the driver in case of failure.

By the time the team also includes a woman, the only between 23 men: It's called Matilda T, 30 years, Image Manager Chesterfield. All 24 people on your team are involved full time, in the year, the field Raid Marathon, but quantifying the human force needed for the conduct of the entire project is impossible. All employees of Belgarda are co-involved and collaborate with the racing Department even if only intermittently. The pilots, as well as conducting the tests, follow the set up of the bike to be able, during the race, repairs of luck. The pre-race physical preparation, always followed by the head doctor, the profes-sor Bows, includes, during the month before the race, 3 weekly bike trips, 4 jogging sessions, 3 gym (2 read and one with maximum loads), a day at the pool and a complete rest.

Archetti believes that athletes use doping, in African marathons, Since it is impossible to, in an effort so prolonged, dispose of the remaining negatives of such substances, and a pilot who would use would remain a victim of the accumulation of fatigue. Talk about costs is virtually impossible. In addition to bike, estimated value 300 millions of lire una, the means of assistance, aeroplanes, dozens of people leave, the thousands of hours of work dedicated to the project, We must consider the occasional engagement of all employees and other dozens of people Belgarda (photographers, suppliers, etc.) who collaborate to the realization of “African dream”.

OW94-06

Peak and Neveu will be in charge of two new Yamaha OW 94. Driven by peak at Rallye des Pharaons, the OW 94 is the evolution of the OW 93 entrusted to Mad and the fourth rider. Identical in design, the new Yamaha differ in reinforced frame and a modified suspension in linkages and length of the swingarm; the engine is different in the heating unit (piston and piston rings of new material) and has larger carburetors and has a higher compression ratio.

OW94-05The candle is now only, in place of the previous two, the power is 60 HP, two more, but mostly the consumption decreased. OW94-04In detail the technical characteristics are as follows: displacement of 752 CC (105 x 87 mm), four-stroke single cylinder engine with five valves, two Mikuni Carburetors from 30 and 32 mm, five-speed gearbox, Kayaba fork with adjustable compression and rebound, excursion to 300 mm, monocross rear suspension with adjustable Ohlins super, excursion 280 mm, Michelin front 90/90×21 or 100/80×19, rear 140/90×18.

Autonomy is entrusted to two tanks, side main, a total of 58 liters; the weight of nearly 220 kg in running order and the maximum speed is over 185 km/h. The instrumentation, In addition to indispensable roadbook, includes a trip master tech, digital and analogue magnetic electronic compass of reserve. After his second place in last edition, second place at “Pharaohs”, the official Yamaha, entrusted to the French team Sonauto, is a top candidate to victory .

Marinoni-1985

The Yamaha XT to Dakar 1985

The XT to Paris-Dakar ' 85 Yamaha attending the Paris-Dakar rally were of two types: those officers, prepared directly from the House and managed by the French team Sonauto, who conquered with Olivier second place, and those prepared by Belgarda, that after dominating the competition with Peak have finished third and fourth with the same peak and with Mad. We have analyzed the version prepared by the Italian team because, approaching closer to mass production, lets make some interesting comparisons.

Belg85-12The motion of Belgarda represents a real collage, because it uses parts of the TT600, the XT 600 Ténéré and 490 by cross. The frame is that of TT 600, braced at the rear to support the weight of the extra fuel tanks and tool bag. In particular it has been soldered a reinforced tube that goes from the attack of the swing arm from under the seat. Compared to the standard chassis then added two skid tubes, one on each side, for increased protection, and the Centre stand for easy servicing.

Swingarm “official Yamaha”

The fork and the rear swingarm were provided directly from Yamaha and they equal those of motorcycle officers. The fork has the stems from 43 mm such as the TT 600, but has the sliders with the quick release front wheel. Clear springs are reinforced for extra weight that must endure. The swingarm is an experimental model a bit higher than that of series. The rear shock is to set, While the spring again this is reinforced to withstand greater load.

The wheels shall be those of the 490 by cross. The tires were mounted, Depending on the land, with the air Chamber, putting behind a double Te rim to avoid tearing the valve, or the «mousse» solid rubber. The «mousse» in particular has been used on the rocks or on hard surfaces where the risk of puncturing is very high.
The braking system is a cross between what the XT 600 Ténéré and the 490 by cross. On the front there is the hard braking with the Group of Ténéré (pump and caliper) the cross bike which ensures greater reliability. At the rear is the drum brake group are from cross.
The engine is the TT 600, structurally identical to that, the Ténéré but already in the beginning a bit more powerful (about 2 more horses) and above all more generous in low. To earn another shot at low was replaced the camshaft with that preparation kits that Belgarda markets, and has been given special attention in the design of the Terminal part of the free outlet exhaust, which also takes advantage of the OEM manifold. It has also been changed to accommodate the Carburetors calibrated airbox on the tank.

In the race then you used the barrel of the Ténéré with cane in. cast iron instead of TT with the chrome barrel. Are also standard clutch and gearbox, the latter is how all that as scaling relationships. He spoke instead on the final report, adapting gradually to the characteristics of the route with the Crown replacement. The chain is strengthened, of the type used on dirt bikes.

Tank Byrd from 39 Lt.

The tank has a capacity of 39 litres and is the same as the preparedness kit, Inside is completely blank; the pilots themselves have renounced sponge inside because the half-empty tank of fuel to annoy not shaking the Guide and earns a liter capacity. The side tanks were made specially by Belgarda. The water, required for regulation, has, a capacity of 6 liters, that of petrol by 10.
The superstructure is completed from the saddle of the Ténéré, from a rear fender Acerbis and windshield, enclosing the radiator of the ollo (the Ténéré is set next to the engine). The fairing protects the instrumentation that includes tachometer, speedometer with trip-master and oil temperature thermometer. Behind the fairing are also the compass and a cassette for the roadbook
