In 2008, Harley added anti-lock braking systems as a factory installed option on all VRSC models.^[63] Harley also increased the displacement of the stock engine from 1130cc (69ci) to 1250cc (73.6ci), which had only been previously available from Screamin' Eagle, and added a slipper clutch as standard equipment.

Its really nice. I don't knew it. Thanks for your information...
