A LAP OF DONINGTON 2.487 MILES OF THROTTLE-STOP ACTION
1 START/FINISH LINE
RR: 126.94mph SE: 125.98mph No surprise that both bikes log virtually identical speeds, having just accelerated out of Goddards, what with them both having identical power, tyres and electronics. For reference, 123mph seems to be a typical speed at the start/finish line for a litre bikes, with the exception of the Suzuki GSX-R (which logged 129mph), so both ZX-10s are right where they should be.
2 CRANER CURVES
RR: 16.29s SE: 16.39s Both ZX-10s are right at the very sharp end of the best times set for the descent from Redgate to the Old Hairpin. The SE logs the same time it takes for the Aprilia RSV4-RF to do it, and the RR misses out on the fastest overall time, held by the Yamaha R1, by just 0.03sec. Both bikes can definitely turn.
RR: 88.25mph SE: 86.51mph Through the bumps and surface change at Coppice, both bikes are at full lean, and loaded up with over 1g of lateral acceleration, and Rutter is trying to rinse as much traction out of the rear tyre as he can. Both ZX-10s give strong accounts of themselves, but it’s the lighter, slightly more nimble RR that takes the honours here, with a speed that’s just 0.1mph off the boss of Coppice, the Aprilia RSV4-RF
RR: 59.97 mph SE: 58.92 mph Both bikes are about on par for an apex speed at the Esses. Nudging 60mph, the RR is at the upper end of what litre bikes can manage through the wide, but single-line chicane, which makes it quite a challenge at the sort of pace Rutter is running at. For reference, the R1M managed 58.53mph, and the Fireblade SP 59.03mph
5 BRAKING (100mph-40mph)
RR: 3.33s/102.28m SE: 3.4s/103.61m Both bikes record solid braking distances and times from 100mph to 40mph, which puts them right in the mix with the rest of the litre bikes. Considering the two bikes have the same brake set-up and tyres, and ABS, we are putting the slight difference in performance down the extra kilos that the SE carries over the RR, rather than any theory regarding active suspension vs passive suspension, not least because Rutter could barely tell the difference between the two.
