Ummmm, unless he swapped wheels with someone, that's not an S2R1000. Likely and S4Rs.
Result would have been the same either way....
It's an S2R1000 with 10 spoke forged Marchesinis on it, I can see how that would throw you off. ..... well technically it's an S2R1000 with 1080cc big bore cylinders and pistal high comp pistons, but whose counting. Off the line it's arguable whether an S4RS is faster as this motor make more torque at a much lower RPM, but the S4RS is definitely faster on an interstate roll.
