The donor bike for this amazing build is a 1988 Yamaha XT600Z Ténéré. Originally, the bike was in horrible shape, abandoned in a garage. As it was gathering dust in the corner, the inspiration started long before the actual building process. The original spoked wheels were the beginning of the inspiration for this build.
Before beginning the building process, the bike was stripped to the chassis. All the bare parts were exposed to clearly see where the bike needed reinforcements. The back was then shortened and the bike was taken to a powder coating facility.
The bike has clip-on handlebars with leather bicycle grips and cotton ribbons. Underneath the rider sits a XS 750 tank that was perfectly fitted for this build.
A pair of Showa 43mm upside-down forks were installed at the front end, coming from a Ducati 916 SPS. The forks were disassembled, overhauled and finished in an anodized black color. Front brakes are replaced with Brembo 4 pot calipers with a 320mm floating rotor.
The original piston was replaced with a forged high-compression one that ups the displacement to 630cc. Combined with a new hotter camshaft, new exhaust system, machined head and a pair of 35mm Keihin FCR flat side carbs, the old single piston now cranks up power up to 9000 rpm.
Maintaining the original hubs, new San Remo 18" aluminum rims were installed in the front, with a 17" fat tire at the rear. This combo is famous among road going bikes, so the swingarm had to be replaced with one coming from an older generation XT that fits perfectly the Ducati 1098 adjustable monoshock suspension.
All electronic controls have been stripped to bare essentials and have been elegantly fit in the top dashboard of the bike.
Despite originally being an off-road bike, the Proto-Moto forgot all about its dusty origins. Now it likes to eat up asphalt and burn rubber, taking sharp corners and pulling strong in every twist of the throttle.
