The Yamaha TT 600 RE (DJ012/04) represents the final, refined chapter of the air-cooled TT lineage. A unique engineering highlight of this specific variant is its production heritage: manufactured by Belgarda in Italy, the ‘RE’ was the first and only TT to successfully bridge the gap between hardcore enduro performance and daily usability by integrating a reliable electric starter system while intentionally reducing suspension travel to lower the center of gravity and improve seat accessibility.
Engine & Lubrication Performance
The heart of the DJ012 is the legendary 595cc single-cylinder SOHC engine. Unlike its predecessors, the RE model focuses on thermal stability. For maintenance, 2.1 liters of SAE 10W-40 (JASO MA) is critical. Given the air-cooled nature, using an oil with high shear stability is essential for protecting the top end during slow-speed trail riding. The NGK DPR8EA-9 spark plug should be inspected every 6,000 km to ensure optimal combustion and easy starting.
Electrical System: The ‘E-Starter’ Evolution
The introduction of the electric start required a significant redesign of the left engine casing and the electrical loom. The GT7B-4 battery is the cornerstone of this system. Due to the high compression of the 600cc thumper, ensuring a healthy battery state-of-charge is paramount; a weak battery can lead to premature wear of the starter clutch (sprag clutch), a known sensitive point in high-displacement singles.
Chassis and Handling
Equipped with 21-inch front and 18-inch rear wheels, the TT 600 RE maintains its off-road pedigree. The recommended 1.5 bar (22 psi) pressure is a versatile baseline for dual-sport use. While the RE features slightly shorter suspension than the ‘R’ model, the Sachs rear shock and Paioli forks provide a plush ride that excels on fire roads and technical B-roads.
MotoSpecsLab Verdict
The Yamaha TT 600 RE (DJ012/04) is a masterpiece of utilitarian engineering. It trades the ‘R’ model’s extreme terrain capability for the reliability of an electric start and better road manners, making it one of the most sought-after modern classics for adventure travelers and weekend enduro enthusiasts alike.
