Consistent further development of the Due Plus. The cylinder head consisting of two parts is completely surrounded by coolant and thus cools the combustion chamber more effectively. The combustion chamber is thus cooled more effectively and more evenly, increasing the compression ratio by approx. 7%. Even at low engine speeds, a significant increase in performance is noticeable. The reduced temperature simultaneously increases the operational safety and the service life of the cylinder.

The DUE PLUS cylinders from Top Performance are clearly designed for speed and performance. Thus Top Performance drove an impressive record home with the DUE PLUS. With a special chassis, which somehow reminds of a suppository, a speed of 159,38km/h was driven in 1996 with an engine power of 17,6kW.

The cylinder is delivered with a coated Asso piston, which facilitates the break-in phase considerably and contributes to a perfect lubrication.

The channel layout and workmanship catapult the DUE PLUS cylinders into the midrace category. Trimmed for performance, the DUE PLUS develop more than 9kW. Due to the very high speed level of approx. 12000 rpm, they should be driven with a racing shaft to prevent damage to the crank drive. Indispensable to ensure full performance and durability is also here a 17,5mm carburetor and a suitable exhaust with short resonance length.
