we purchased this bike at the time for me(10 years old) and my brother (13 years old) we both rode it for about a year. for about three years the bike sat in the garage. then i took the bike out for a ride and it started up on the third kick, without being ran in three years. when i started riding it again i would check the tire pressure, the oil and gas every weekend. the only thing i've done to the Dr-z125l bike was added new tires and change the oil every two months, and other small maintenance to the bike.
