Royal Enfield Himalayan 750 price in Kolkata

I’ve been riding a Himi450 for 2 years and want to upgrade to a bigger, twin-cylinder bike with more power and refinement — thinking about a Himi750 or BMW F450. A new Himi750 may launch in about a year; should I wait for the new model or buy an existing bike now? I also own a Ford Freestyle (2019, 58,754 km) and drive up to 250 km weekly. If I upgrade my car, I want a powerful, refined, reliable SUV with 4×4, no sunroof, and only essential safety features. Should I buy a new or used for the car, and which options would fit these needs?
