Some products do have very extended lead times. This has been an issue for many months now and not just for Cisco, but many companies. Cars are in high demand/short supply, months long backorder on refrigerators and dishwashers, etc.
That said it's not impacting all models. I show the MX95 &105 being readily available. Perhaps work with your reseller and see if a MX95 would meet the needs/can be negotiated to a reasonable price for you. If it has to be the 85 unfortunately there's no getting around the delay.
