• 8.2:1 compression ratio, 37 kW (50 DIN HP) at 6500 rpm, max torque 56.7 Nm at 5000 rpm

Special Tools and Reference Charts

The manual reproduces BMW’s own special tool photographs with order numbers (valve spring lifters, mandrels, pullers, frame gauges, master gauges, and more), plus reference charts for fluid capacities, tire pressures, oil grades, and DIN/metric conversion — the kind of shop reference material that’s otherwise scattered across multiple sources.
