should be the same as its the same stroke 52 ml and its not full circle just standed so im 90% sure they are the same ,,there is no reason for them to be different
OLD 125's had a smaller crank but still 52 stroke.. they failed alot so increased the size of the crank web and crankcase respectivly.. this is the only thing i can figure that explains the rumors about 125/180 cranks being different (as in theres pics of people asking why there 180 is bigger) piaggio recon there identical.. others say different,m i recon the old cranks are the reason as they WERE smaller. but this is only on the OLD typhoon/hex engines. like p reg onwards they did a better engine
thought on piaggio diagrams there showed a 2mm difference between the 125 and 180 125 one 52 and 180 ones 54 if i remember
You drunk monty? Piaggio don't give fuck all information on their part diagrams. Both the 125 and the 180 runners have the same crankshaft part number.
maybe not piaggio then i have seen a diagram somewhere but not seen it for ages drunk. yes always :mrgreen:
ye, i remember it being on drag.com.. somone messured 2 up, the larger comming from a 180 and the smaller comming from a 125.. i recon it was an OLD 125 wiht the small webs. rather than it just being a smaller crank in the 125. makes sence of the last few years of unknown diameter as every 125 and 180 ive striped has had an identical crank bar the series one engines with there tiny crank/case
