The Radical Caribbean SR3 Cup is the region’s premier one-make racing category in which all competitors race in identical 1340cc SR3s. 

The championship was established at Bushy Park in Barbados but visits circuits in Trinidad and Guyana also, with a truly multinational roster of drivers, many of whom dovetailing their Caribbean Cup campaigns with outing in Radicals other international series.

Due to the warm Caribbean climate, the series enjoys a longer season than many other championships, with rounds commencing in February and the finale in November.

The fastest race cars in the region


The Radical Caribbean SR3 Cup first ran in 2018, a four-round series contested at head-lining race meetings in Barbados, Guyana and Trinidad & Tobago. The launch of the regional competition followed three successful seasons of the Barbados-based Suzuki Challenge Series (SCS), which also hosted the off-season Radical Carnival for three years, attracting drivers from Europe and the United States.

Regional motor sport rivalry is nothing new – racing drivers and motorcyclists have fought for supremacy for six decades or more, something which surprises many who see cricket as the major sport in the West Indies. Organised racing and rallying has existed since the 1950s, with travel between the territories common even in the early years, long before the phrase ‘sports tourism’ was coined.

The series is administered by Bushy Park Circuit Inc (BPCI), which was appointed sole distributor for Radical Sportscars in the Caribbean at the end of 2017. The company liaises with the Organising Clubs in each of the host countries to ensure a level playing field for all competitors and is responsible for co-ordinating the shipping of cars around the region, along with the technical support team and spares package.
