Though Yamaha would eventually made a 490 cc version of this bike, many felt that the bigger bore required to make more power wasn’t worth the trade-off of a slightly sluggish start off the line. Even today, the 465 feels snappy off the line and makes plenty of off-idle torque.

Model years of the IT series within Yamaha were distinguished by suffix letters. In 1982, Yamaha released the “J” bikes, so this is also known as an IT465J. There are only subtle differences from the previous year’s “H” models, though at the time this was the biggest displacement off-roader that Yamaha made. These bikes were on the heavy side, so the rear shock is rather stiff. Large jumps result in hard landings – just make sure you keep the nitrogen filled up!
