My Suzuki manual offers this for metric bolts. Thought it might be useful. First number is bolt diameter in mm. Second number is lb-ft for 'conventional' or 4-marked bolts. Third number is for 7-marked bolts. I assume that by 7-marked bolts they mean the fine thread hardened kind. When you actually measure bolt diameter on the threads, you'll find them a little undersized. If you measure bolt holes on the threads, you'll find them a little oversized. Big bolts take a lot of torque to tighten properly. It's really easy to under-tighten them. Enjoy!
