Alvaro Bautista came to the WorldSBK championship and has been unstoppable. Since figuring out how to get the right feeling from the front end of the brand new Ducati Panigale V4R, he has won all six races held so far – four full-length races, and the two new Superpole sprint races held on Sunday. His winning margins in the four full races were 14.983, 12.195, 8.217, and 10.053 seconds. He won both sprint Superpole races by over a second as well.
Naturally, that kind of domination attracts attention. The WorldSBK series is meant to be a close battle between bikes based on road-going motorcycles, and as modification of the standard bikes is limited, there are mechanisms in the rule book for keeping the disparity between the different bikes racing to a minimum, giving any manufacturer which sells a 1000cc sports bike a chance to be competitive.
To ensure this, the rules have a section on balancing performance between the different bikes competing. The method of balancing performance has varied over the years, but the current rules use only the maximum revs to try to keep the bikes close. The maximum rev limit is set when each new model is homologated, following a formula described in the rules, and explained by WorldSBK Technical Director Scott Smart in a video on the WorldSBK website. The short version is that the bikes are limited at 1100 RPM above the point at which they make their peak horsepower.
