Data notes
‡
Corrected value. The source published this figure under the wrong unit. The metric figure is authoritative and the imperial value shown here is derived from it.
- Ground Clearance: shown as 0.8 ft in (source stated a value inconsistent with its own metric figure of 245 mm)
Method. Figures are manufacturer reference specifications, not measurements. Every value is checked for unit consistency, physically possible magnitude, and plausibility for its equipment class before publication; figures that fail any check are withheld rather than shown, and figures reconstructed from related data are marked above. Imperial and metric figures are reproduced as published, except where a note states otherwise.
