Yamaha XS 850, produced in 1980 one more motorcycle which is made by two phases.

In the beginning of 1999 we bought Yamaha XS850 from USA. At that time we haven’t knew what kind of project we were making but know we know it was Cafe Racer. Even if it’s 20 year old but after all those Russian models it was simply wow. Not much time passed and we found another XS at USA auctions. We thought it could be a perfect one for spare parts. There was no discussion, we need to press button “Enter” and here he’s mine, few months later bike have landed on a Lithuania pavement. Engine is working quite well for 1980 of course it’s smoking a bit, but for this kind of year it’s legal. Speedo shows 18000 miles. It looks good but at the start of the season XS have touched one of the service corner.

Summer is almost reaching second half old and dusty XS have been taken out of the corner for rebuilding. Once again assessed its condition we thought there is no time for making something huge, lets make a fast project because season ending is coming much faster than expected and we want to say Farewell with a XS to motorcycle season ending. Like all “Cafe Racer” models we needed to take of a bit of weight: rear fender, flashers (each weights more than a 0,5 kg.), air filter box, center stand and many other parts were removed or cut down.

Beauty procedures. End of the bike is made of the glass fiber, fuel tank is the same, front chassis from Suzuki GSX750. Honestly when we made GSX750 project we removed it’s front chassis so it made a perfect replacement for Yamaha XS 850. Brake system is also from a GSX750. Of course we had one big problem how to fit original front wheel in the new and not the same chassis. Rear brake cylinder is taken from a some kind of street bike. Because we’ re taking everything so serious we managed to make a exhaust our own with a three exhaust tips. Sound was completely redesigned and it’s truly astonishing. Steering was set for one reliable item – ClipOn type. Passenger footpegs now became drivers footpegs. Sitting position on a bike is quite strange, when I sat on it I remembered one Anthony Hopkins movie “The World’s Fastest Indian” sitting position. Overall painting, fuel tank was black so I couldn’t resist to repaint it in all in black. But only black color isn’t so awesome, so brake hose and spark plugs were changed to the yellow ones.

Electricity and other stuff. Headlight was taken from a storage parts. Taillight was taken from Harley Davidson Electra Glide front turn signal. Battery is now at the bottom of the frame. Whole electricity, all wiring was hide, some of it near fuel tank, others in plastic. Seat was together made with a STL. At the end of the season XS was fully prepared. At that same weekend I managed to drive with it more than 500 km and even reach 205 km/h.
