Kestrel Take

A seriously capable middleweight adventure bike — the 790 Adventure's low-slung fuel tank, punchy parallel-twin, and genuine off-road ability make it a favorite for riders who actually leave the pavement. It's more off-road focused than a big GS. KTMs get ridden hard and want diligent maintenance. A clean, un-bent 790 Adv with records is a hugely capable machine; verify service and inspect for off-road abuse.
