For those seeking only the very finest in performance parts, these carbs are for you. The FCR Flat Slide carbs from Keihin represent their top-of-the-line offering.

Developed specifically for all models of new Triumph Bonneville, these are not some cobbled-together kits built in the backroom of some bike shop.

These carbs include a new Throttle Position Sensor.

The BASIC KIT includes the twin FCR39mm carbs, two velocity stacks, two manifold spigots and is pre-jetted to match the user’s bike.
