yes, both hv their own advantage/disadvantages ..no clear winner here ...it all depends on user requirement ....i think gd110 can beat cg only in longer run because of SOHC nature of revving at higher rpm, plus gd110 seems to be a gas guzzler too for its category .. so it should do it...but again, gd110 is heavier than cg and produces less bhp ... so how could it do it ..
technically, OHV engine does put out more torque at lower rpm which OHC just can't, whether it uses a longer stroke or not ...it just each engine hv their advantages and disadvantages .. just like 80s two stroke yamaha RX 115cc, which can clean sweep all 100,125,150 ohv/ohc bikes available here in a matter of seconds ... but two stroke hv their own disadvantages ...
