The BMW F 800 S, designated internally as the 0216, represents a significant departure from BMW Motorrad’s traditional Boxer and K-series lineages. Historically, the F 800 S is renowned for introducing the world’s first mass-produced parallel-twin engine utilizing a unique ‘dummy’ connecting rod. Instead of traditional balancer shafts, BMW and Rotax engineered a third connecting rod attached to a weighted balance arm to counteract primary and secondary inertia forces, resulting in a twin that mimics the smoothness of a Boxer while maintaining a compact vertical profile.
Technical Engineering Overview
At the heart of the F 800 S is the 798cc liquid-cooled engine. This power plant was designed to be high-revving yet fuel-efficient. The chassis features a bridge-type aluminum frame with the engine acting as a load-bearing element. One of the standout features of the ‘S’ model is its single-sided swingarm paired with a low-maintenance belt drive, offering a cleaner and quieter alternative to traditional chain drives.
Maintenance Guide & Essentials
Lubrication System
For optimal performance and clutch longevity, the 0216 requires 3.0 liters of SAE 10W-40 oil. It is critical to use oil that meets JASO MA2 standards to ensure the wet clutch does not slip. Given the high-revving nature of the Rotax twin, checking oil levels via the dipstick at operating temperature is mandatory for accuracy.
Ignition & Electrical
The electrical system relies on the YTX14-BS battery. Due to the BMW CAN-bus wiring system, owners should use a dedicated BMW-compatible smart charger to avoid damaging the ZFE (Central Vehicle Electronics) during winter storage. The NGK DCPR8E plugs should be inspected for carbon fouling every 20,000 km, ensuring the 0.8 mm gap is precise to prevent misfires.
Tires and Handling
The F 800 S is sensitive to tire pressure. For solo riding, 2.2 bar (front) and 2.5 bar (rear) provide the necessary compliance for sport-touring. When fully loaded with luggage or a pillion, increasing to 2.5 bar (front) and 2.9 bar (rear) is essential to maintain the integrity of the 180/55 ZR 17 rear carcass under load.
MotoSpecsLab Editorial Verdict
The BMW F 800 S remains a masterclass in middleweight engineering. While early models faced minor teething issues with rear hub bearings, the 0216 series is generally robust. Its combination of a lightweight aluminum frame, the innovative balance-rod engine, and the maintenance-free belt drive makes it a sophisticated choice for riders who value technical efficiency over raw displacement.
