As I said, Molinoman, there were 8 --somewhat subjective-- attributes besides measured performance data. Here's a totally unedited translation of the score sheet for you:
1. Engine: RIII
68, HD
60
2. Overall performance;: RIII
51, HD

3. Road behavior (stability, manoeuvrability, etc.): RIII
40, HD

6. Ergonomics, weight, riding pleasure, etc.: RIII

7.b Standards equipment: RIII

That's how HD got 337 points. I personally thing the mag has been... indulgent towards the Road King
