How different are MotoGP and SBK? We talked about it in depth when Carmelo Ezpeleta revealed that Kawasaki had asked for a wild card to ride a MotoGP stage. As we imagined Jonathan Rea struggling with Marc Marquez and all the other riders on the grid, we looked at the Jerez track (read HERE), a track where historically the differences are minimal between prototypes and derivatives.
This video allows to observe these differences from a very privileged point of view, that is Jonathan Rea's Ninja's tail and Marc Marquez's RCV's tail, both engaged on the same track, precisely Jerez. The time trial sees the MotoGP winner on this specific lap, but it is interesting to note the points on the Spanish track where Marquez literally digs a ditch compared to Rea's Kawasaki. In particular, the point where the performance gap between the two bikes is clear from the images is the longest straight of the track, which precedes the curve currently named after Dani Pedrosa.
During the initial acceleration and also in braking, Marquez's Honda clearly detaches Rea's Ninja, which at other points of the track seems to be able to keep a pace similar to Marc's, especially in the fast corners. Maybe in those moments the SBK chassis and Pirelli tyres are able to contain those differences that in other parts of the track are more marked.
There are a thousand other parameters to evaluate in order to have a real comparison, because these are not the respective records of the two riders on the Andalusian track, we don't know how different the temperature was when the videos were shot and obviously we don't know the tyres used by both of them. Some elements emerge, however, and for those who have a particularly sharp ear, it is also possible to perceive very well the different way the electronics work out of the corners between the two bikes.
