The 87.9cc Husqvarna 390 XP Chainsaw was widely produced from 2006 – 2013, and is still produced and available today in some markets.
Here’s how it was described in 2012:
A very powerful saw from our latest generation of large professional saws. The 390 XP® is engineered with the professional logger in mind. Designed for the most demanding conditions a logger may face.
Performance is increased while vibration is diminished through Husqvarna’s two-mass principle isolating the engine from the handles. Excellent ergonomics and low power-to-weight ratio makes the 390 XP® very desirable on the work site. XP®
Keep in mind, there will be some variation in specs and features over time.
