This is a common assumption, but no less untrue for it's frequency - as a popular example the 50cc two strokes can be as low as 2hp or a mighty 9hp, even more... but this is based on quality & design, not brand or retailer. "There's no replacement for displacement" a misunderstood misnomer to say the least.
Research carefully before you buy, dismiss all advertising with a very
large grain of salt - if the specifications are unavailable and/or cannot be confirmed by another, unaffiliated source... it's likely untrue
