KTM introduce KERS system
KTM have revealed that they have been pioneering the use of a Kinetic Energy Recovery System (KERS) in their 125cc racing models – making them the first manufacturer to use the system competitively in any form of motorsport.
KERS is a form of energy saving technology that harvests and stores energy generated through braking, which would otherwise be lost as heat, and applies this energy during acceleration. It’s application is primarily in the interests of improved performance and fuel economy and the technology is set to be trialled by a number of teams in the forthcoming Formula One season.
BMW Sauber has tested the technology in F1 but KTM’s use of the system in the final Grand Prix of 2008 at Valencia is the first time that KERS has been used competitively.
The KERS system, which does add weight to the bike, was tested by Tomyoshi Koyama. The Japanese rider, who finished seventh in the Grand Prix, was chosen to test the system as he usually requires ballast in his bike to meet minimum weight regulations without a KERS system.
Koyama, who was the third fastest KTM at Valencia, recorded a top speed of 219.6kmh, some way behind the fastest circuit speed of 226.3kmh recorded by Aprilia’s Stefan Bradl, suggesting KERS did not make an overwhelming difference.
Nevertheless, KTM boss Harald Bartol believes that the system does have potential, claiming that it develops an extra 2kW (2.68hp).
“It is a hybrid system,” Bartol told Sol Moto. “Under braking some condensers [capacitors] are charged – we do not call them batteries because a battery would never charge so quickly in deceleration – and the energy is then released during the following straight. That gives us some 2 kW extra, although we only use it when the motorcycle is in third, fourth, fifth or sixth gear.”
