Sunstar EPTA Stage 0 race rotors - increased heat dissipation

Sunstar ' s new EPTA Stage 0 ( zero ) racing brake rotors are used by many top teams , including the Kawasaki Puccetti World Supersport team ( Can Oncu and Attack Yamaha Performance in AMA SBK in the United States - Jake Gagne and Cameron Petersen ). Standing for " Enhanced Performance Torque Application ", the name EPTA is taken from the ancient Greek for seven - representing the durable , reliable , high-strength seven-point mount system between the carrier and the pad track . The AL 7075 hard anodised aluminium carrier / hub ( 30 ยต m ) mounts to a 5.8 mm induction hardened stainless steel rotor , with Sunstar ' s proprietary sevenpoint EPTA disc flotation mechanism . The rotor is machined with grooves with ventilation holes machined in the pad track , for better cooling , and

optimised lightening holes to avoid vibration onset . Sunstar Sales Manager Gianluca Olivieri told IDN : " The straight 3 mm thick profiles protruding from the wave shape on the outer diameter of the disc form a radiating area that dissipates heat , without being touched by the pads , but with a higher thermal inertia than the rest of the disc . The ' radiators ' have been shown to help heat dissipation by up to 36 degrees C less than the maximum temperature measured on Sunstar ' s standard EPTA rotor for SBK use . puccetti

GIVI ' s made in Italy S510 D-Charge combines charge and charge maintainer functions and is compatible with traditional 12V lead-acid and lithium batteries . It is compact , robust , safe to use , with automatic cycle management and equipped with everything necessary for connection to the vehicle . This maintenance item is a new addition to GIVI ' s extensive range of accessories . The design of the GIVI S510 D-Charge " extends battery life by up to four times and achieves maximum efficiency in terms of energy consumption . Primarily intended for the two-wheel sector , it has features that make it suitable for operation with other vehicles , including cars ". It is compatible with all types of traditional 12V batteries ( lead-acid , MF , GEL , AGM ) and with the latest generation 12V lithium batteries with either lithium-ion or Li-FePO4 technology from 1.2Ah up to 100Ah . The charge and maintenance algorithm that manages lithium batteries works on seven cycles in a clever , 100 % automatic way . The cycles indicated are initialisation , recovery ( starting from a minimum of 1.25V ), light charge , main charge , analysis , maintenance and equalisation .

With lead-acid batteries , the charge and maintenance algorithm that handles conventional batteries follows a similar automatism to the one described above , adding an important eighth desulphation cycle . Through a process that uses current pulses , sulphates are removed from the lead plates , restoring the battery to its functionality . Safety features include protection against sparks , reverse polarity , short circuit , overloading and overheating .
