How much should a wallet friendly entry level road bike weigh?
A "wallet friendly" entry level bike should weigh as little or as much as your wallet allows.

The key here is entry level. For the vast majority of people in the market for a entry level bike (and most racing cyclists), the weight of the bike is not the limiting factor. All things considered, 8.5kg is not absurdly heavy for a bike, it's actually a shade lighter than my current racing bike, which is more than capable on hilly and flat races.

Bottom line, lightweight and wallet-friendly are usually mutually exclusive when it comes to bikes. Don't worry about the weight, and enjoy the ride.
