The Sigma 150 engine was an upgrade to the original Sigma 125. This included higher lift cams, bigger injectors and most importantly, throttle bodies. Not only did this engine produce an additional 25bhp to its stock variant, it transformed the driving experience. Throttle bodies add character in spades, transforming average engines in racing machines, with razor sharp responsiveness and a soundtrack that will send pulses soaring.

This Roadsport SV 150 offers a brilliant balance between character and usability. The 150bhp provided by the engine up front is just right for enjoying the open roads, with enough grunt to keep anyone entertained, and with plenty of drama from those throttle bodies.

The larger SV chassis offers the space and comfort thanks to the well refined Roadsport options, including Caterham’s softer suspension set up, supportive but very comfortable leather seats, cockpit heater and full weather equipment.

Finished in metallic Dodge Viper Blue this Roadsport looks classly, drives brilliantly and makes for an all round excellent drivers companion.
