  1. Hi feetupfun ,, my cota engine is together , already assembled , , so what I rember 200 cota is really 175 cc , and has same crank wrist pin of 125 , it’s a small wrist pin , I have ventured into looking into installing other brand pistons into different bike ,, close , not same usually different wrist pin & Bering , // #&% ,,, have seen on internet , if my memory , correct , some one installed a Vespa piston into a cota 200 , with a little matching, top of piston , for deck height , this was years ago , I believe he had it bored to ,,, , now , you have to research all Vespa for the Wright ,, proper wrist pin size ,, , 1 ,, then hope to match deck height , ,, I heard years ago the were going to mf more pistons for cota 200 ,, ya well there not enough bikes out there for them to make a profit ,, I suppose , if you watch ebay check once and while a 200 piston comes up , I know the the Oregon dealer. Had one 20 over , just this last few years for sale And sold it , so there out there , so France trial classic , is selling upon waiting delivery Tarabusi brand piston 63.95mm for E 177.00 you can put your email in for the waiting list , cheers info from larry
