Castrol: Liquid Engineering for Every Engine

Castrol has a long and proud history developing motorcycle lubricants and has worked with bike manufacturers and racing teams to push the limits of oil technology in our dedicated motorcycle R&D facility in Pangbourne, UK. Within this state-of-the-art facility lives Flossie, our unique robot test rider.  

Flossie

Unlike a human biker, Flossie doesn’t feel fatigue and is impervious to the impact of harsh climates. So, she can be programmed for precise shifting in test rides spanning excessive durations within extreme temperatures.

Conducting this type of torture testing ensures that our lubricants provide optimal protection, unsurpassed performance and rapid acceleration at the touch of the throttle. Whether you ride a modern street racer, v-twin cruiser or prefer an off-road adventure bike, Castrol has an oil to suite your bike and riding style.
