OEM Aprilia Oil Dipstick - 1A009604 (ex 1A007269)
O-ring 873233 sold separately.
Oil level is checked with this dipstick not threaded in.
Aprilia changed to this dipstick starting in 2017, and to be honest we wish they hadn't. Unlike the earlier sight window design, this dipstick only accounts for the top 300cc of your oil capacity. So even if your stick is bone dry, you could still have as much as 3.5 liters of oil in your engine.
