In years in the mid-80's, houses pushed very evolution of its own means, every year we witnessed the arrival of juicy news: from the most alternative progressive systems, the adoption of a cooling liquid for carry-on Nikasil barrels cylinder until the front brake and sopsensioni etc.
It is true that the others vintages were still of great turmoil technical and underwent further modification, a clear sign of the evolutionary thrust of the period that led to the very top of the market cross, it was one of the most flourishing periods at both bikes deployed in an official from the houses in the various national and world championships, both of practitioners.
In the world, many houses pledged to the official level, deploying more than two bikes to race.
The specifics of this particular vintage, there was an epoch-making change, especially in engine technology of codeste bike that went almost all the cooling liquid and the first reports appeared in Nikasil in place of cast iron pipes universally used.
Lower classes had already witnessed the metamorphosis few year earlier, after 1980 or so, with the Italian houses in the first row.
The Cagiva factory made right at the end of 1979 one of the first 125 cc bike water cooled.Another major change was the mass adoption of the brake front disc, a real treat for the time.
Moving on to a fast synthesis technique, remained loyal to the "air cooled" Yamaha and Suzuki.
In the case of the RM, the bike was essentially the same as in 1983, the swing arm, was the last year when they did, it was built exclusively for the European market, was the only 500 cc Hamamatsu's house with the parking brake front disc, in the United States was never imported.
The YZ 490 '84 changed, version 85 was the only difference front disc brake.The Honda put his hand heavily on the 500 project, producing a cutting-edge motion, liquid-cooled bike almost new compared to 84 . The KX, he turned to liquid cooling, cylinder liner with Nikasil and in the rebuilding of the bike including the progressive rear systems.The germany Maico made 'a good liquid cooling for its 500 cc,front disc brake front, but the motion was substantially the same as the previous vintage.
The Swedish Husky, was one of those that changed more radically, by the double rear shock absorbers replaced by a new rear progressive system to a single shock absorber, liquid cooled, front disc brakes and very particulary frame with a big pipe.The same KTM totally remade their 500 cc : Liquid cooled barrel Nikasil, new chassis and front disc brake. should be noted that the version for the American market came out that the WP UPD and bigger fuel tank, the European version mounted instead of the traditional Marzocchi fork 41 mm and little tank and a more tapered, as an option you were inverted forks and a choice between Dell'Orto and Bing.The Cagiva made in 1983 its 500 cc, the engine acquired projects Villa, but only in 1984, the model series saw the sun.It was the first 500 cc water cooled and the front disc brake , in fact paved the way for the other sisters ...
Just the Cagiva was the last of eight sisters recovered from me.
Although it was built just a few miles from my home, I struggled just to retrieve it, it was over in the U.S., only to find themselves near London as well as in the den!
