Mega ZX21 DSIII Circuit engines

Following on from the announcement of the updated engine line by Mega, comes the release of the ZX21 circuit engines. Available in 2 versions, the new DSIII is available as standard and also as an Eduardo Modified version. The standard version features an improved liner-fit, the liner is seated a little higher in the crankcase creating an even better alignment with the ports. The EM version additionally has a black-case, improved lighter crankshaft with silicone, hand-selected piston/liner/conrod combination, tear-drop workings on the ports. Both engines sport new graphics on the cooling head.
