Yamaha XT600 Tweety Is a Fully-Fledged Flat Track Racer With…

The project began with an old Yamaha XT600, which was immediately disassembled upon acquisition. The aim was to create a minimalist flat tracker with custom bodywork and updated components, leading to the removal of much of the bike’s original equipment. With the motorcycle in pieces, the first task was significant frame modification.

The stock subframe was replaced with a custom-built version. A new swingarm was installed, featuring a reinforced pivot point and paired with an adjustable aftermarket shock absorber. The original forks were swapped out for higher-spec ones, which were shortened by 15 centimeters (5.9 inches) before installation.

Billet aluminum triple clamps from Luca Venturini connected the forks to the steering stem. In the wheel department, laced Excel rims were fitted with Maxxis flat track tires. Since there’s no front brake, the rear brake system was upgraded, including a new wave-style rotor and a refurbished Nissin caliper to ensure optimal performance.

The cockpit was stripped of its standard components, retaining only essential parts. A wide flat tracker handlebar was mounted on custom risers, with no mirrors or dials present. The bike was clearly designed as a racer, so no lighting was added.

While the engine’s internals remained mostly unchanged, it received new breathing components. Air is drawn in through a 3D-printed intake, and the exhaust system features a high-mounted Zard pipe ending in a premium Spark muffler. These modifications are impressive, but the highlight of the build is the stunning monocoque bodywork that combines the fuel tank, seat pan, and tail section into a single, striking unit with a polygonal surface. The only other piece of bodywork is a transparent front number board.
