[Star Wars] Unless General Grievous was force sensitive, how was he even remotely fast enough to duel with Obi Wan?

I feel your question doesn't quite reflect the nature of what happened. Grievous was a cyborg and his mechanical limbs actually allowed for the incredible speed with which he could attack. His spinning attack could strike ~20 times a second and would overwhelm most opponents, so speed is not the issue, and we know he had killed jedi before. The real factor in question is Obi-Wan.

Obi-Wan was able to go toe to toe with Grievous' speed as Obi-Wan had absolute mastery of the defensive lightsaber style of Soresu. Very few Jedi could have stood up to Grievous' attack on their own, but Obi-Wans speciality allowed him to block, counter and parry the onslaught of blows from Grievous.
