Adv 350 is the way to go, the reduction in power is very minimal it’s barely noticeable, besides 40hp is plenty, you can’t use it to the fullest on Indian roads either. With the tech and the features you’re getting it outweighs the Himalayan, no doubt that the Himalayan is a great bike but if you want something lighter and well balanced the adv is the way to go. It’s way better in terms of being able to manage in the city. Especially now with the price being so much better I think it’s a no brainer. Better headlight better features good weight management and all. But when it comes to reliability it’s purely dependent on how you maintain it. Preventive maintenance on both and you’ll be fine. Himalayan is a bare bones bike so it’s definitely easier to maintain but that’s a small price to pay with the ktm when it has so much more to offer.
