Derbi Variant intake kit Carburettor 28mm MRD

SWR MRD Intake kit for Derbi Variant with a 28 mm carburettor.

If you have tuned the engine, it makes no sense to leave the intake as the bottleneck. The SWR MRD kit combines a 28 mm carburettor with the Metrakit V3S by Moto Tassinari Reed valve, forming a set designed for tuned 2-Stroke engines that need intake performance to match the rest of the engine.

28 mm Carburettor: its larger diameter increases the mixture flow area, reducing intake restriction when the engine demands a higher flow rate. On a tuned Derbi Variant, this makes it possible to feed the cylinder more effectively as RPM rises. With correctly adjusted carburation, the aim is to achieve stronger throttle response when opening the throttle, greater punch, and a stronger pull in the upper range.

Metrakit V3S by Moto Tassinari Reed valve: it controls the entry of the mixture into the crankcase and plays a fundamental role in the response of a 2-Stroke engine. Its design is intended to promote intake flow and crankcase filling, helping to achieve quicker response and fuller power delivery. In a well-balanced tune, this translates into more punch at low revs, better transition through the mid-range, and greater ability to keep feeding the engine when it pulls hard at high revs.

This is where the package makes the difference. The carburettor provides the intake capacity and the V3S manages the entry of the mixture into the crankcase. When the cylinder, exhaust, and carburation are correctly matched, the engine can make better use of the greater available flow, achieving better response to throttle input, fuller delivery, and a stronger pull. An intake designed to accompany a serious tune, not simply to fit a larger-diameter carburettor.

The MRD intake system has been developed and tested on a dyno and track, with the aim of optimising intake flow and overall performance. A solution intended for Derbi Variant builds where the goal is to get the most out of every component and achieve an engine with more aggressive response and racing character.
