Factory owner's handbook. Covers TT-R90 (3P2); 2007 Australia owner's manual 3P2-28199-81, English. Chart columns: initial 1000 km (600 mi) or 1 month or 30 hours, then odometer readings 3000 km (1800 mi) or 6 months or 90 hours and 5000 km (3000 mi) or 12 months or 150 hours. NOTE: from 7000 km (4200 mi) or 18 months, repeat the maintenance intervals starting from 3000 km (1800 mi) or 6 months, so items marked at both 3000 and 5000 km fall every 2000 km (1200 mi) or 6 months, and items marked at 5000 km only fall every 4000 km (2400 mi) or 12 months. No annual check column. Air cooled, carbureted, chain final drive, drum brakes front and rear (shoes).
