This 1965 BMW R69S, owned by the seller for 36 years as its second owner, features a custom-built sidecar and a clean Kansas title. The 594cc flat-twin engine received new oversized pistons less than 2,000 miles ago and a new magneto coil last month, with modifications including a lower final drive ratio and stiffer suspension to accommodate the sidecar. The odometer shows 37k miles, though actual mileage is reportedly lower due to the final drive change, and it comes with significant spares including the original final drive and workshop manuals.
